One of the oldest attested usages of the proverb “physician, heal thyself” is directed at this character in the opening scene of a play in which this character fills hearts with “blind citadels of hope.” In a scene unusual for featuring four non-chorus characters on stage at once, a reluctant third character accompanies gods representing Power and Force while this character remains silent. This character is attended by a chorus of Oceanids (-5[1])who doubt his epithet of (*) “The Forethinker.” The fragmentary second (10[1])play of an Aeschylus trilogy about this character inspired a lyrical drama of the same name by Percy Shelley in which this character is released from his chains. For 10 points, name this Titan who is “Bound” in a play whose lost sequel calls him “the Fire-Bringer.” ■END■
