The Attikos deme Erkhia was located near the modern Spata, approximately twenty kilometers (twelve miles) east of Athens, with the deme center located at Magoula. The deme of Erkhia is unique as we have recovered an elaborate sacrificial calendar--the Greater Demarkhia--listing sacrifices, costs and rules for the festivals held under the supervision of the demarch. The calendar prescribes 59 annual sacrifices to 46 separate divinities, including heroes, nymphs and Gods, and some of them seem unique to the deme.

The Gods most frequently honored at Erkhia were Zeus, Apollon, Kourotrophos ('She who raises the young') and Athena. A few times a year, the men traveled to Athens to sacrifice to Zeus an Athena 'of the city', to Apollon Lykeios, and to Demeter of Eleusis. For worship at the deme, Erkhia had its own Akropolis, where the same Theoi were worshipped as on the Akropolis at Athens, as well as more obscure Gods, like Zeus Epopetes, the Heroines, the Herakleidai, the nymphs, and the Tritopateres, as well as local heroes like Leukaspis ('he of the white shield') and Epops.

Two of these sacrifices are upcoming: the one to the Leukaspis on the 20th of Mounikhion and the sacrifice to the Tritopatores on the 21th of Mounikhion. This is an announcement for the PAT ritual for the sacrifice to Leukaspis.

Leukaspis is the name of a good few heroes in Hellenic mythology. The most famous is the one depicted here on a drachma from Syracuse--designed around 405-400 BC by Eukleidas. Leukaspis, 'He of the White Shield' was a famed warrior and hero and tied to the myth of Herakles:

“While Heracles was making the circuit of Sicily at this time he came to the city which is now Syracuse, and on learning what the myth relates about the Abduction of Kore, he offered sacrifices to the Goddesses on a magnificent scale, and after dedicating to Her the fairest bull of his herd and casting it in the spring Cyanê, he commanded the natives to sacrifice each year to Kore and to conduct at Cyanê a festive gathering and a sacrifice in splendid fashion. He then passed with his cattle through the interior of the island, and when the native Sicani opposed him in great force, he overcame them in a notable battle and slew many of their number, among whom, certain writers of myths relate, were also some distinguished generals who receive the honours accorded to Heroes even to this day, such as Leucaspis, Pediacrates, Buphonas, Glychatas, Bytaeas, and Crytidas.” (Diod. Sic. IV 23)

As he was a Sican of Sicily, and apparently non-Hellenic, it's quite unlikely he was the one worshipped at the deme of Erkhia. It was most likely another Leukaspis that was a local hero. What, exactly, the source of this Leukaspis' renown was has been lost to us.

Alternatively, Noel Robertson in 'Religion and Reconciliation in Greek Cities', page 173, notes:
“When we meet Leupaspis at Erchia, we should not imagine that a Sican hero was brought to Attica.  Instead, the same name has been given to similar powers in the two places.”

Leukaspis appears not to be so much a war hero in Erkhia but a, what Robertson describes as a 'functional hero'. In Hellenic warfare a hoplite presses on the enemy with his shield, so that a buffering wind may well be likened to a shield-bearing warrior. As such, Leukaspis might have been a power associated with winds and tied to the begetting of a good harvest. So we wrote the ritual in that sense and used the two Orphic Hymns that best fit, To Zephyros and To Notos.

According to the Greater Demarkhia, the sacrifice to Leukaspis was a ram, along with a 'libation not of wine'. In modern times, a libation of milk, honey, and/or water will most certainly do.
