Erechtheis

The inscription reads: “Of the Erechteid Tribe, died at war in Cyprus, in [[Phoenicia, at Halieis, at Egina, at Megara, the same year.’ Follows a list of 170 dead, among whom are two strategoi and a soothsayer.]] Erechtheis () was a phyle (tribe) of ancient Athens with fourteen demes, named for the legendary king Erechtheus.

The phyle was created in the reforms of Kleisthenes. Although there is little specific reference to the tribe, an inscription dated to either 460 or 459BC in the form of a casualty list allows a little access. Two generals are listed for the single year on which the text insists, Ph[ryni]chos is followed in the list by Hippodamas, possibly indicating that he succeeded the former in the summer due to the death of Ph[ryni]chos. Alternatively they were elected together which was not uncommon later. The presence of a seer on the list is surprising, as their role of accompanying the army to interpret omens through the analysis of the entrails of sacrificed animals does not seem particularly dangerous.
