Erchia
Erchia or Erkhia was a deme of ancient Attica, of the phyle of Aegeis, sending six or seven delegates to the Athenian Boule, but eleven delegates after 307/6 BCE. According to Stephanus of Byzantium, in Greek mythology, the name comes from an inhabitant of the deme who hosted Demeter.
History
Much of what is known about Erchia comes from a lex sacra of the deme. In it are listed 59 annual sacrifices to 46 divinities, for a total cost of 547 drachmae; 21 of these sacrifices were made in the deme itself, the other 38 in the neighboring demoi or in Athens.From its central location within Attica, and the wealth and positions held by many of its inhabitants and from the number of its delegates to the Athenian Boule, more than any other deme of the phyle Aegeis, it can be assumed that Erchia was one of the most important demoi.
In Erchia there was a shrine of Hecate.
