Elephenor received the sons of
Theseus of
Athens,
Acamas and
Demophon, when they fled from the usurper
Menestheus.[4][5] One source states that he unwittingly killed his grandfather
Abas and was expelled from Euboea; because of that, he had to assemble his troops before the Trojan expedition on a rock of the
Euripus Strait opposite Euboea.[2]
Trojan War
Elephenor was a
suitor of Helen[6] and the leader of the Euboean force of thirty or forty ships which joined the Greek expedition to
Troy.[3][7][8] On the day the truce was broken by
Pandarus, he was killed by
Agenor whilst trying to drag off the body of
Echepolus.[9]
The Return
On their way home, Elephonor's men were driven off course and shipwrecked off the coast of
Epirus, where they founded the city of
Apollonia. Alternately, Elephenor survived and settled on the island
Othronos, but was soon driven out of the island by a serpent and went to Abantia in Illyria.[2]
