Who is Thoas from the play, Iphigenia in Taurus?

Thoas is the king of Taurus. He is a barbarian (barbarian then meaning stranger, not savage) king, in the eyes of the Hellenes. He proves a rather unthreatening enemy to the Hellenes. Although he questions Iphigenia about her disposition of the prisoners, she easily deludes him. He submits to her order to purify the temple with fire while she goes to the ocean to purify the statue and prisoners. When he learns of Iphigema's trickery, he commands his soldiers to follow the escapees but once again submits to the voice of reason, this time in the form of Athena.
