Echelidae

Echelidae or Echelidai (Ἐχελίδαι) was a deme of ancient Attica. It was so called from the hero Echelus, and lay between Peiraeeus and the Heracleium, in or near a marshy district, and possessed a Hippodrome, in which horse-races took place.[1][2] It is probable that this Hippodrome is the place to which the narrative in Demosthenes refers,[3] in which case it was near the city.[4]

Its site is unlocated.[5]
