Īon

1. Greek tragedy (with a happy ending) by Euripides, probably written a little after 412 BC. It deals with the story of Ion as in (1) above. The essential features of the plot—a woman seduced, her child exposed, the subsequent recognition, and happy consequences—became typical of New Comedy (see COMEDY, GREEK 6; also MENANDER).

2. Dialogue by Plato (see 2) named after a rhapsode of that name.
