The deme of Erkhia has many sacrifices, and Elaion has pretty much adopted them all. One of these sacrifices--or actually two of them--are on Poseideon 16. Both are to Zeus. The first to Zeus without epithet, the other to Zeus Horios: 'of the boundary stones'. Will you join us for this combined sacrifice on December 24 at 10 am, EST?


Zeus Horios is responsible for the preservation of boundary stones. In order to mark their territories (especially between public and private), the ancient Hellenes relied on boundary markers, called 'horoi'. A horos (χορός) was usually a stele of marble or limestone, no larger than a meter high, rectangular and roughly hewn except for the upper front face, which was dressed smooth for inscribed letters. It was usually inscribed, sometimes with just the word 'horos', or sometimes specifying the territory (e.g., 'horos of the sanctuary'), or even the name of a deity. Some horoi were inscribed in the first person; a famous horos stone found by the ancient Athenia agora reads 'I am the horos of the Agora'. Specificity and clarity were crucial; passersby needed to know what sort of land they were entering because a boundary marker's message was enforced with a legal enforceable meaning.

The Arkhian calendar describes the sacrifices as such:

"[...] on the sixteenth [of Poseideon], for Zeus, on the rock or rocky place at Erkhia, a sheep, no taking away. For Zeus Horios, at Erkhia, a piglet, no taking away."

'No taking away' in this case means to consume the sacrifice on the spot. No part of it can be carried away from the site. So the skins and bones, as well as some of the meat are to be burned and the rest of the meat eaten, not sold or stored. Some scientists and archaeologists have come to call this type of sacrifice 'Ou phora', after Scott Scullion's definition.

In Sullivan's definition of 'Olympian' and 'Khthonian', 'Khthonian' was extended to include not only sacrifices in which the victim was destroyed, but also all sacrifices from which the meat could not be carried away and had to be consumed on the spot. He connects ou phora sacrifices to Khthonian deities or heroes, but this theory has been widely debated because it simply does not seem to resonate with other knowledge we have of these divinities and Their cults.

Poseideon was ruled by Poseidon, Zeus and Dionysos. Poseideon is the first true winter month; the first harvest was over, seafaring had ceased and thus war had come to an end. The focus was on the home and preparation for true, deep winter: the weather turned and the crops needed protecting. Because of this, it was also a month of threat; if the crops failed, if the seas became too rough when a daring fisherman was out on it, or if a river went out of bounds and flooded a well populated area there would be death. Zeus Horios watches over the boundaries of the home and was thus vital in this divine protection.

In current times we might not have most of these fears, but we still want trespassers to stay off our property (burglars, anyone?), and we want our personal, emotional, boundaries to be observed as well by the people we meet. Zeus Horios still influences our lives. So will you join us in honoring Zeus and Zeus Horios come December 24 at 10 am, EST?
