ECATOMBÆON, Ἐκατόμβιον, in Chronology, the first month of the Athenian year. It consisted of 30 days, and began on the first new moon after the sum-
mer solstice, and consequently answered to the latter part of our June and beginning of July. The Boeotians called it Hippodromus, and the Macedonians Lous. See MONTH. The word is a derivation from the Greek ἑκατόμβον, a hecatombe, because of the great number of hecatombs sacrificed in it.
