EUPHORBUS, son of Panthoüs, one of the bravest of the Trojan heroes, slain by Menelaus (Iliad, xvii. 1-60). Pythagoras, in support of his doctrine of the transmigration of souls, declared that he had once been this Euphorbus, whose shield, hung up in the temple of Argos by Menelaus, he claimed as his own (Horace, Odes, i. 28. 11; Diog. Laërt. viii. 1).
