A mysterious being, about whom the following tradition was current at Athens. During the battle of Marathon there appeared among the Greeks a man, who resembled a rustic, and slew many of the barbarians with his plough. After the battle, when he was searched for, he was not to be found anywhere, and when the Athenians consulted the oracle, they were commanded to worship the hero Echetlaeus, that is the hero with the echetlê, or ploughshare. Echetlus was to be seen in the painting in the Poecile, which represented the battle of Marathon. (Paus. i. 15. § 4, 32, § 4.)
