Important architectural remains and movable finds dating back to the period of Mycenaean civilization were recently revealed during excavations at the Acropolis of Gla in Boeotia, the Greek Ministry of Culture announced this week.
The Mycenaean Acropolis of Gla, part of a settlement dating from the 13th century BC, was built on a natural rock outcrop. After its fortification it became a fortress for the outlying population, who were engaged in cultivating the fertile plain below it. The area also served as a flood control center associated with the Mycenaean-era drainage and irrigation system, which used water from Lake Kopais.

The 50-acre area which was fortified by stout walls during Mycenaean times is seven times larger than Mycenae itself. The stone walls, which are miraculously preserved along their total length of 3 kilometers (1.86 miles) and thickness of 5.40 to 5.80 meters (up to 19 feet), are easily visible today and form an extraordinarily impressive sight.

According to the Ministry of Culture, the most recent excavations conducted as part of the 2018-19 archaeological dig uncovered six symmetrical stone blocks used in building construction.

Numerous storage vessels, including jars and amphorae, as well as cups and utensils, decorative frescoes, lead sculptures, and figurines — all of which represent a familiar, common cultural and artistic tradition of the times of Mycenaean expansion — were also unearthed.

The Mycenaean Acropolis of Gla itself was destroyed by fire and abandoned a little before 1200 B.C.
The painstakingly-constructed drainage system on the plain below was abandoned as well and the lake once again flooded the area, as it had before the years of improvement and development in the golden age of Mycenae.

Mythologically speaking, Pegasos was originally only one winged horse, born from the neck of Médousa when she was beheaded by the hero Perseus. Poseidon, Tamer of Horses, is his father. Hesiod describes in his ‘Theogony’ the curious circumstances of his birth:

"…Medusa who suffered a woeful fate: she was mortal, but the two [of her Gorgon sisters] were undying and grew not old. With her lay the Dark-haired One [Poseidon] in a soft meadow amid spring flowers. And when Perseus cut off her head, there sprang forth great Chrysaor and the horse Pegasus who is so called because he was born near the springs [pegae] of Ocean [Okeanos]; and that other, because he held a golden blade [aor] in his hands. Now Pegasus flew away and left the earth, the mother of flocks, and came to the deathless gods: and he dwells in the house of Zeus and brings to wise Zeus the thunder and lightning." [ll 270-294]

Pegasos was tamed by Bellerophon, a Korinthian hero, who rode him into battle against the fire-breathing Khimaira. Pindar, in his beautiful Olympian Odes describes this cooperation wonderfully:

"Bellerophon, who once suffered greatly when beside the spring he wanted to harness Pegasus, the son of the snake-entwined Gorgon; until the maiden Pallas brought to him a bridle with golden cheek-pieces. The dream suddenly became waking reality, and she spoke: “Are you sleeping, king, son of Aeolus? Come, take this charm for the horse; and, sacrificing a white bull, show it to your ancestor, Poseidon the Horse-Tamer.” The goddess of the dark aegis seemed to say such words to him as he slumbered in the darkness, and he leapt straight up to his feet.

He seized the marvellous thing that lay beside him, and gladly went to the seer of the land,  and he told the son of Coeranus the whole story: how, at the seer’s bidding, he had gone to sleep for the night on the altar of the goddess, and how the daughter herself of Zeus whose spear is the thunderbolt had given him the spirit-subduing gold. The seer told him to obey the dream with all speed; and, when he sacrificed a strong-footed bull to the widely powerful holder of the earth, straightaway to dedicate an altar to Athena, goddess of horses.

The power of the gods accomplishes as a light achievement what is contrary to oaths and expectations. And so mighty Bellerophon eagerly stretched the gentle charmed bridle around its jaws and caught the winged horse. Mounted on its back and armored in bronze, at once he began to play with weapons. And with Pegasus, from the chilly bosom of the lonely air,7 he once attacked the Amazons, the female army of archers, [90] and he killed the fire-breathing Chimaera, and the Solymi. I shall pass over his death in silence; but Pegasus has found his shelter in the ancient stables of Zeus in Olympus." [13. 63]

Pegasos was not worshipped with ritual and sacrifices like the Theoi—the Hellenic Gods—were; only the Theoi were worshipped in that manner, and even then there were huge differences in Ouranic, Khthonic, and hero worship. He/they were featured in art, though, and was/were a beloved part of the Hellenic mythology; especially the Pegasos Bellerophon rode on, as he was featured on many coins throughout the years.
Forty-two years ago, one of the most important archaeological discoveries in the world, and the definitive proof of Macedonia’s Greek origin, was announced by Greek archaeologist Manolis Andronikos. On November 8, 1977, Andronikos discovered a pair of royal tombs from the fourth century BC which contained many objects of gold, silver, bronze, and iron, several wall frescoes, and two caskets of human bones, which he believed to be the remains of the parents of Alexander III, Philip II and his fourth wife, Olympias.

It was the crowning achievement of Dr. Andronikos’s career, in the village of Vergina, in northern Greece. He had been excavating there for 40 years, finding rich tombs and artifacts from ancient times along the way — but nothing he had ever uncovered could prepare him for what he unearthed that day.

Finally, at a depth of 17 feet underground, he struck the largest tomb at the site and announced the discovery of the tomb of King Philip II, who lived from 382-336 B.C., This was the very Macedonian king, who had conquered all of Greece and was the father of Alexander the Great.

Dr. Andronicos, a professor of archeology at the University of Salonika, based his stunning conclusion on ivory busts found on the tomb floor which greatly resembled known portraits of Philip and Alexander. Chemical dating placed the tomb at the right time, between 350 and 320 B.C., and in addition, it is known that other Macedonian king was buried in northern Greece during that time.

At the time the magnificent tomb was discovered, scholars said it was one of the most splendid and important archaeological finds since World War II. They generally, though cautiously, accepted the evidence that associated the tomb with Philip II. Among the treasures of the tomb were the first complete paintings from the Hellenistic period, exquisite silver and gold ornaments and weapons, as well as a marble sarcophagus containing a gold casket with bones believed to be those of Philip.
The Golden Larnax, housed at the Archaeological Museum of Vergina, contains the remains of Macedonian King Philip II.

Dr. Andronikos believed that a smaller casket might have held the remains of Olympias, the first of Philip’s seven wives and the mother of Alexander the Great. In his book, “Vergina: The Royal Tombs,” Andronicos says the discovery provided “new information about Macedonian Hellenism.”
Previous knowledge concerning Philip II had been based almost exclusively on Athenian literary sources. However, the archaeologist noted that the view from Athens was often biased, because Macedonia was a serious political rival of that city. The discovery appeared to confirm a previously disputed theory that Vergina, and not Edessa, which is farther north, was the site of Aegae, the capital of ancient Macedonia.

Andronikos was born in Bursa, in northern Turkey, in 1919 and began studying classical archaeology at the University of Salonika in the 1930’s, receiving his doctorate there in 1952. He spent two years of post-doctoral studies at Oxford University. He first excavated in Vergina in 1937 as a student assistant. But his work was interrupted by World War II and the Greek Civil War in the late 1940’s. He was a member of numerous scholarly societies, including the Archaeological Society of Athens, the German Archaeological Institute of Berlin and the Society for the Promotion of Hellenic Studies in London.

In 1982, Andronikos received the “Olympia Prize” from the Onassis Foundation. Just a few days before he died, he received Greece’s highest distinction, the Grand Cross of the Order of the Phoenix.
Andronikos died at the age of 73, on March 30, 1992 at a hospital in Thessaloniki, where he had lived. He had liver cancer and had also suffered a stroke. But his magnificent discovery of the tomb of Philip II of Macedonia will live in the annals of history for all time to come.
A touch of Roman today. Marcus Vitruvius Pollio (80–70 BC – after c. 15 BC), commonly known as Vitruvius, was a Roman author, architect, civil engineer, and military engineer during the 1st century BC, known for his multi-volume work entitled De architectura. His discussion of perfect proportion in architecture and the human body led to the famous Renaissance drawing by Leonardo da Vinci of Vitruvian Man. He was also the one who, in 40 BCE, invented the idea that all buildings should have three attributes: firmitas, utilitas, and venustas, meaning: strength, utility, and beauty. These principles were later adopted by the Romans. His only surviving work is 'De Architectura.'

De architectura (On architecture, published as Ten Books on Architecture) is a treatise on architecture, dedicated to his patron, the emperor Caesar Augustus, as a guide for building projects. As the only treatise on architecture to survive from antiquity, it has been regarded since the Renaissance as the first book on architectural theory, as well as a major source on the canon of classical architecture. It contains a variety of information on Greek and Roman buildings, as well as prescriptions for the planning and design of military camps, cities, and structures both large (aqueducts, buildings, baths, harbours) and small (machines, measuring devices, instruments). Since Vitruvius published before the development of cross vaulting, domes, concrete, and other innovations associated with Imperial Roman architecture, his ten books are not regarded as a source of information on these hallmarks of Roman building design and technology.

A few paragraphs from Book 1 today.

“The building of temples relies on symmetry and architects need to most carefully understand the reason for this. It comes from proposition, which was called “analogy” in Greek. Proportion derives from fixed segments of the parts of the building and the whole—and the balance of symmetry is achieved through this. For no building can have an order in its design without symmetry and proportion, unless it has something like the precise design of a well-figured human body.  For nature has so composed the human body that the face from the chin to the top of the brow and the roots of the hair is one tenth of the whole and the palm of the hand from the wrist to the end of the middle finger is the same.

The head from the chin to the top is one eighth and the top of the chest where it meets the neck to the hair’s roots is a sixth. From the middle of the chest to the crown is one quarter of the whole. The third part of the length of the face extends from the bottom of the chin to the base of the nostrils. The nose from the nostril base to the space between the brows is the same. From that line to hair forms the forehead, a third part. The foot comprises a sixth of the body’s height and the chest is a quarter. The other limbs all have appropriate measures too. And ancient painters earned great praise by observing all these measures.

In the same way, the limbs of temples should have proportions of their various parts responding appropriately to the general size of the whole construction. Consider that the navel is the natural center of the body. For, if a person should lie on the ground with hands and feet spread wide and a circle has the navel as the center, fingers and toes will touch the line of the circumference. In addition, a square can be traced within the figure in the same way. For, if we take the measure from the sole to the top of the head and compare to measure to the distance from one hand to another, the lengths will be found equal, just like foundations squared with a rule. For this reason, if nature designed the body so that the parts correspond in their dimension to the whole design, then ancient people seem to have decided with good reason that they should keep in their works the exact proportions of the separate components to the design of the whole. Therefore, they have handed down orders in all of their works, especially in temples to the gods, the kinds of accomplishments whose excellence and weakness persist for generations.”

Great quantities of porfyra (murex shells) and buildings of a Minoan settlement were located in excavations by the Lasithi Ephorate of Antiquities west of the islet of Chrysi where ancient carved fish ponds have survived on the coast. The numerous broken porfyra shells found in the rooms of the houses are evidence of a very early cottage industry of porfyra dye established during Crete’s first palaces. The settlement had a flourishing economy not apparent from the architectural remains but from the fine quality artefacts found in the houses.



Chrysi islet is situated in the south of Crete in the administrative Region of Lasithi and belongs to the Ierapetra Municipality. The surface survey conducted between 2008-2011 provided evidence of human activity and habitation since the Bronze Age.

In 2018 and 2019 the by now systematic excavation on Chrysi under the Lasithi Antiquities Ephorate’s Head Chrysa Sophianou, brought to light a large building with many rooms, known as B2, which was inhabited without interruptions during the Protopalatial and Neopalatial period, from the Middle Minoan IIB to the Late Minoan IB period (ca 1800-1500 BC).

The rooms had simple architectural elements, such as built in vats, stone benches, work surfaces, hearths and a staircase with stone slabs. Pottery is a typical mixture of vessels for drinking, eating, cooking and storage, while many stone tools were recovered. It was a surprise to discover no evidence in this entire building of a cottage industry for the production of porfyra, unlike the other excavated houses of the settlement.

Despite their simple architecture, two rooms contained “treasures/hoards” of metal, glass and semiprecious stones. The first treasure was found in 2018 in a room which most probably was used as a storage area. The deposit contained two parts of copper talents, a mass of slag and jewellery: a gold ring, a gold bracelet, 26 gold beads (disc shaped, round and shaped like a papyrus), one bead of silver, 5 of bronze and the band of a bronze ring. There was also a large number of different shaped glass beads (39 round and 25 papyrus-shaped), 4 of so called Egyptian blue, 20 of corneal stone, 1 of amethyst, 10 of lapis, one agate seal depicting a ship whose prow has the shape of an animal’s head and a stone amulet shaped like a monkey.

While continuing the excavation in 2019, another treasure of talents was discovered in the corner of a room in the same building, along with a large saw and three vessels, one made of copper. Their overall weight is 68 kilos and together with the parts of the other treasure they are in all over two talents. It is the largest treasure of metals found to date on Crete. Moreover, stored inside a vessel were pieces of a tin talent. The latter is considered a rare find being the second from the Late Minoan period found on Crete. The first was discovered in a settlement on the islet of Mochlos.

The above data leads to the hypothesis that the inhabitants of building B2 in the Late Minoan period (ca 1500 BC) belonged to a higher social class and played a different part in the society of Chrysi; probably one of administration. They managed production, the promotion of products, the trading of porfyra dye and the import or distribution of metals.

The months of late fall and early winter are relatively light on the festival agenda--Maimakterion, the month we are in now, wasn't even on the sacrificial calendar of Erkhia, for example. This could have at least three reasons: It's getting cold and wet out and the ancient Hellenes held their rituals outdoors, most of the harvesting was done so food was assured or there was nothing that could be done to decrease the shortage, and with the fall of winter, warfare came to a halt; the seas were too rough to go on campaigns and it would soon be too cold to exist comfortably in a war camp. Seeing as these two latter two reasons were the major ones to have festivals, these months are quiet ones. Elaion will host a PAT ritual for the Pompaia November 7, at the usual 10 AM EST.


Let's start with something obvious we do not know about the Pompaia: the actual date of the festival. Parke (in 'Festivals of the Athenians', page 96) states that the Pompaia in honor of Zeus Meilichios was held during the last third of Maimakterion which would be on or after 20 Maimakterion. Parke cites the treatise on the Pompaia by Polemon of Ilion so we're fairly confident he is correct on the date.

What we do know is that the Pompaia was not originally celebrated by the people of Athens, but solely by its priests. Potentially, it was only celebrated by the priests of Zeus. It was linked to purification. It was one of the festivals that, by Classical times, had already lost much of its original meaning, but which was repeated year after year because it had always been repeated year after year--and in general these had been good years. Not having the rite on the calendar could have devastating effects, so it was performed.

The Pompaia followed the Maimakteria during which a sheep was most likely sacrificed and the fleece collected and cleaned. During the Pompaia a second procession took place with the fleece. The fleece--the 'Diòs Koidion', as it was called--was said to have purifying and other magical qualities that would rub off on he who interacted with it, if he stood on it with his left foot. In fact, a sheep skin was used in the Eleusinian Mysteries in this fashion to absolve those who had a lot of guilt to carry around--or a lot of grief. The Homeric Hymn to Demeter mentions her sitting down in a chair covered by a fleece, and there is also artwork of initiates shrouded in a fleece.

The sheep skin was most likely not connected to Zeus at the start of the practice; as we have seen, it had much stronger ties to other deities. The Pompaia rite simply called for a sheep skin. The connection with Zeus most likely happened through assimilation: the rite fell in a month where people prepared for winter and where the weather got harsher. As such, Zeus had a major impact on the inhabitants of Athens; he controls the weather after all. The sheep from which the skin was used became sacrificed to Him as an appeasement, and then the ritually charged skin made its way through the city.

In the same fashion, the kērukeion (κηρύκειον)--better known as the caduceus--the snake-entwined staff that was the symbol of Hermes, was carried through the city. Most likely Hermes was not part of the actual rite; the kērukeion, like the Diòs Koidion, was a powerful symbol which was used to offer protection and purification to the city now winter was upon them. After all, the kērukeion was said to ward off all evil--and the cold, dark, days of winter most certainly had those. Hermes was added through the procession solely by association, but it is doubtful that He also received an animal sacrifice.

The Pompaia--meaning 'to exorcise'--was not popular, and in general these minor festivals were performed by the priests, for the city, without its inhabitants taking part. A small group of priests most likely walked the city with the objects and those who came upon the group would have said their prayers, spoke their wishes, and paid their respects. Yet, they were not included in the ceremony. This rite fell to the priests, so they could ask the Gods to continue placing their blanket of protection over the city.

As we have no ancient priests of Zeus hanging around, we take this responsibility upon ourselves instead. Will you join us on November 7, at 10 AM EST? You can join the community here and download the ritual here.
Five different shipwrecks which have already revealed important findings were discovered recently off the coast of Kasos Island in Greece’s Aegean Sea. During the exploration, which was funded by the Kasos Association of New York and was supported by the municipality of the island, divers discovered a series of archaeologically important wrecks dating all the way back to classical antiquity.


More than one-third of the total area designated to be explored was covered by a total of sixty-seven team dives during the 2019 exploratory season. The initiative will continue in 2020 and 2021 to discover, study and identify findings in what is believed to have served as an important trading route and maritime crossroads area between civilizations for many centuries.

This year’s discoveries include wrecks stretching from modern times all the way back to ancient Greece.

The area of Kasos served as a maritime crossroads for centuries between the great civilizations of the eastern Mediterranean The most recent shipwreck was a boat that sank in the modern era which was carrying construction material. Another shipwreck dated back to the era of the Greek War of Independence in the 1820s. Divers also found fascinating shipwrecks from the Byzantine era, from the 8-10th century AD, and even an ancient Greek ship which is believed to have sunk in the 1st century BC.

The very oldest shipwreck to be founding the recent dives off the coast of Kasos dates back to the 4th century BC. This wreck contained four different types of ancient pottery, making its discovery particularly important archaeologically.

Among the other items uncovered during this diving season were individual amphorae and other ceramics as well as an array of other objects used during the specific eras of each of the wrecks.
Philicus, or Philikos, of Corcyra was a poet and tragedian, as well as a priest of Dionysos at Alexandria in the reign of Ptolemy II Philadelphus (285-246 BC). Sadly, nothing survives of the 24 tragedies attributed to him. Philicus, however, did write a Hymn to Demeter in choriambic hexameters which has been partially preserved on a stone slab. Unlike Horeric and Orphic hymns, this was not a cult song. It was an exercise in poetry.

The hymn is focussed on the cult of Demeter, which was very popular at the time. It narrates some part of Demeter’s search for Persephone, and told how the earth was rendered unfruitful. It also tells the story of how bashful Iambe made the Goddess laugh and lifted her grief off of her.

As part of the Stenia ritual I reconstructed a part of the hymn into a readable whole but I would share what remains of the rest of the hymn as well. It seems that the first part of the hymn was a speech by a fellow Goddess. Whom this is, is unclear. It could be Peitho (Persuasion), who consoles Demeter, forecasts the institution of the Eleusinian Mysteries, and offers her assistance in recovering Persephone from the underworld. But more likely it's the oracular Titan Dione. She is sister of Rhea, Zeus’ mother. Her inclusion would fit the mythology and various lines. There is, however, no evidence for a close connexion of Dione with Demeter, and therefore no reason why she should intercede in this poem on Demeter’s behalf.

I am very intrigued by poetry fragments or obscure pieces like this and greatly enjoy reading them. I hope you enjoy it as well.

She ceased, and the nymphs and Graces joined in just Persuasion,
and whole swarms of women in a circle about her caressed the ground with their foreheads
and gathered the only living growth from the cropless earth to cast as foliage upon the goddess
But Halimous dispatched the old woman, who had lost her way in the mountain haunts, but arrived at a good time
as a result of some chance: for solemn occasions can an amusing tale be unprofitable?
For she stood and uttered at once in a bold, loud voice: “Do not throw goat-fodder:
it is not this that is a remedy for a starving god, but ambrosia is the support for such a delicate stomach.
But you, divine one, should give ear to Attic Iambe's little benefit;
I am one who has poured out unschooled words, as well as might a chattering living in a distant deme: these goddesses

and from the women, look!, there is grass as a gift, a timorous deer's diet.
None of these things do I have for my gift: but if you loosen up your grieving, then I shall release…”

So, some of you might have noticed, but the Elaion website had died. Sigh. It happened twice, actually. Both times, it was hacked through malware. Very annoying. I've spent quite a bit of time trying to weed the coding out of the old site, but eventually I decided that enough was enough and made a new site with mostly the same information--all updated, of course. It's still a work in progress, but it's back up and kicking at least.

Archaeologists in Greece have located a "major treasure" of Minoan origin in a Bronze Age settlement on a small island in the Libyan Sea, the culture ministry said Friday.


A team excavating on the tiny island of Chrysi south of Crete for over a decade have unearthed a 3,800-year-old Bronze Age compound containing gold jewels, glass beads and the remains of bronze talents, the common unit of value of ancient Greece.

Some of the beads are of Egyptian origin, the culture ministry said in a statement.

The archaeologists also found ancient fish tanks and large amounts of porphyry -- a prized purple pigment of the ancient world derived from sea snails, and later the colour exclusively reserved for Roman emperors.

"The amount of broken shells found...show a very early Mediterranean production of porphyry dye. The cache constitutes one of the most important (Minoan treasures) ever found in Crete until now."

The Minoan civilisation, a naval superpower of the Bronze Age era, flourished on Crete and other Aegean islands until about 1500 BCE.
The days of purification are placed on the 18th and 19th of every month of the Hellenic festival calendar, and are thus part of the Mên kata Theion, the sacred month--religious events that return every month in a set sequence. These days of purification are hinted at in Proklos' 'Commentary on Hesiod's Works and Days', and further solidified by Philokhoros in his 'On Days'. The text is not available online in translation, as far as I can find, but in short, these texts indicate that 'the eighteenth and nineteenth of the month are devoted to purificatory and apotropaic rites.'

While this can be interpreted as a monthly thing, in context it can also be interpreted as something belonging only in Boedromion, tied to the Mysteries at Eleusis. Because we have no conclusive evidence in favor of either theory, I prefer to keep these as a monthly event.

The impure days are the days before the Deipnon. One of the most important of the many Hellenic festivals is the three-day transition from month to month. Although unlinked, the Deipnon, the Noumenia and Agathós Daímōn are held on consecutive days, around the new moon. The Deipnon (Hene kai Nea)--or Hekate's Deipnon--is celebrated any time before the first sliver of the new moon is visible. In practice, this is the day after the new moon. The impure days are thus the two or three (depending on if the month is hollow or not) days leading up to the Deipnon. These days are labelled 'impure' as a precausting. The Deipnon itself is absolutely impure, after all.

Hekate’s Deipnon is the traditional time to end the old month and prepare for the new one. In ancient Hellas, the Deipnon was celebrated with a Supper for the Titan Hekate--made up of leek, egg, cakes, fish, unions and garlic--and set out at the outside shrine to Hekate, and then placed at a crossroads as an offering to Her--Hekate Trioditis, Goddess of Crossroads--and the vengeful spirits who were in her following. In addition to placation, the Deipnon is also a time of purification; in ancient times, a dog was taken in, touched by all members of the oikos so any lingering miasma was transfered to the dog. The dog was then sacrificed in a holókaustos. This was most likely not a monthly thing, but only performed when the household was troubled. As Hekate's sacred animal is a dog, the sacrifice also served to regain, or keep, Hekate's favor upon the household. The house was also thoroughly cleaned so the new month could start fresh the day after. Debts were repaid on this day.

Purificatory rites, obviously, refer to katharmos--ritual purification--in relation to miasma--ritual impurity. Within Hellenic practice, miasma (Μίασμα) describes the lingering aura of uncleanliness in regards to a person or space through which contact is made with the Gods. Miasma occurs whenever the space or person comes into contact with death, sickness, birth, sex, excessive negative emotions and bodily fluids. It also comes from a lack of contact with the Hellenic Gods. Not the actual acts of dying, sex and birth cause miasma but the opening up of the way to the Underworld (with births and deaths) as well as contact with sweat, blood, semen, menstrual blood and urine pollutes us. Miasma is an incredibly complicated and involved practice and it's often misunderstood. The most important things to remember about miasma is that it holds no judgment from the Gods, and that everyone attracts miasma. It's a mortal, human, thing.

So let's look at the terms of 'purification' and 'apotropaic' as noted in the ancient texts. The practice of purification is called katharmos (Καθαρμός). The process of katharmos is elaborate because the process not only involves the physical but also the emotional, mental and spiritual. It means being physically clean when entering ritual but, peraps more importantly, it means leaving behind negativity, worry, pain and trouble before getting in contact with the Gods.
Katharmos is a Hellenic basic. There can not be ritual without katharmos. As such, it makes sense to have days in the month assigned especially to getting clean before the rest of the month's rituals take place.

The word 'apotropaic' comes from Greek apotrepein 'to ward off' from apo- 'away' and trepein 'to turn'. These practices serve to appease polluting spirits, ghosts chief amongst them. Ghosts were the people who could not find the entrance to the Underworld or who didn't have the money to pay Kharon for their passage. Those who were not properly buried were also doomed to wander the Earth for a hundred years. Interestingly enough, Hellenic heroes were also considered ghosts and were honored in the same type of rites as other types of ghosts.

The ancient Hellens held festivals in honor of ghosts, and the Theoi that presided over them, so they would be sated and appeased and would not haunt them. Most of these festivals included a holókaustos--a sacrificial offering given in its entirety to the Gods--and were solemn affairs, conducted at night and without an offering of wine. It was, however, also possible to invite them to dine with the living so they would feel included and then end the proceedings by asking them to leave; something the ghosts would do as it's not polite by the rules of xenia to be a burden on your host.

This fear of spirits and other supernatural entities was named 'deisidaimonia' (δεισιδαιμονία). The ceremonies of riddance were known to the Hellenes as apopompai (ἀποποπμαί), 'sendings away'. There isn't a single word in the English language that conveys the practice. Closest would be 'exorcism'. It is important to note here that these 'exorcisms' weren't performed on people, but on the ghosts themselves and in short, they consisted of rites to ask the Gods (especially Hekate) to keep these unfortunate souls away from their homes and families, because the ghosts could bring misery down upon them. Possession was not part of the fear. Many rites in the ancient Hellenic religion--including monthly ones like the Deipnon--were apotropaic.

There is one other reson I can think of why certain days could have become impure are the ancient Hellenic homicide courts. Homicide courts were the law cases where one man stood accused of murdering another. In many respects, a homicide case resembled other private suits. Each litigant pleaded his own case in two speeches, the first of which presented the main points in his accusation or defense and might be written for him by a logographer, aprofessional speechwriter, and the second rebutting his opponents arguments. Witnesses could testify if they were male citizens. When the litigants finished their two speeches, the jury voted for acquittal or conviction and the majority carried the day (a tie vote meant acquittal). The penalty for intentional homicide was death, though exile seems to have been a common outcome, and the accused was allowed to go into exile voluntarily at any time up until his second speech in court, which would then be delivered by a friend or relative in the hope of persuading the jury to vote for acquittal despite the accused’s departure. For unintentional homicide the penalty was exile, probably for a specific length of time (perhaps a year). At any point the victim’s family could agree to a lesser penalty, or they could even drop the charges, if they wished, though there was a strong moral obligation to avenge an intentional murder.

Interestingly enough, homicide courts were held outdoors out of fear of pollution. The belief was archaic and had become more of a tradition than a rule by the time of Classical Greece, but it was definitely practiced. It could have been that these homicide courts were always planned on impure days--or that these days became impure because these very specific courts were always held on these days.

So, what do these days mean for worship...? Not too much. Festivals were hardly ever celebrated on these days and essembly meetings were rarely held on them either. They were said to bring bad luck; no major endeavor was started on them. Especially the impure days in the middle of the month were considered ominous. For us, we can foolow the lead of the ancient Hellenes: there are no planned festivals and we can be mindful of these days when planning our own celebrations. But the ancient Hellenes would have held regular household rituals on these days and in case of imergency, they would have performed rituals as well. The katharmic rites might have been a bit longer or performed with more intention but overall, these days are just something to keep in mind, not be held back back.
