Lucius Annaeus Seneca,
The Tragedies of Seneca
“ But at this juncture, when no help seems possible from heaven or hell, to their amazed joy, Hercules himself appears, and in the flesh. He perceives the mourning garments of his family, and the grief-stricken faces of the chorus, and quickly learns the cause of all this woe. He at once plans vengeance upon the wretch who has wrought it all. He has, himself, forewarned by a "bird of evil omen perched aloft," entered Thebes in secret; and now he will hide within his own palace and wait until Lycus comes to fetch the victims whom he has doomed to death. ”
