Euphorion (Ancient Greek: Εὐφορίων, Euphoríōn, fl.
431 BC) was the son of the Greek tragedian Aeschylus, and himself an author of tragedies.
[1] He is known solely for his victory over Sophocles and Euripides in the Dionysia of 431 BC.
He is purported by some to have been the author of Prometheus Bound—previously assumed to be the work of his father, to whom it was attributed at the Library of Alexandria,[3]—for several reasons, chiefly that the portrayal of Zeus in Prometheus Bound is far less reverent than in other works attributed to Aeschylus,[4] and that references to the play[clarification needed Which ones?]
If Euphorion wrote Prometheus Bound, then there may be as many as five ancient Greek tragedians with one or more fully surviving plays: Aeschylus, Euphorion, Sophocles, Euripides, and possibly the author of the tragedy Rhesus if its attribution to Euripides is incorrect.
