1 (Gluck: Iphigénie en Aulide). Bar. Husband of Clitemnestre and father of Iphigénie, whose sacrifice is demanded by the goddess Diana before she will allow the Greeks to continue to Troy. Agamemnon is torn between love for his daughter and the need to appease his troops and the gods. Created (1774) by Henri Larrivée.
2 (Strauss: Elektra). Agamemnon does not appear in the opera, but his presence is felt from the onomatopoeic opening bars. He was Elektra's father, murdered in his bath by her mother Klytämnestra and her lover Aegisth, and vengeance for his death is the theme of the opera.
