The New International Encyclopædia/Iophon

I′OPHON (c.450-c.390 B.C.). A Greek tragedian, son of Sophocles. We know little of his life or of his plays. There is a statement in Valerius Maximus attributing the Antigone to him. The story that he accused his aged father of insanity so that he might have control of his property, and that Sophocles proved his sanity by reading to the judges from the Œdipus, is unsupported by any evidence. The few verses of Iophon which survive may be found in Nauck, Tragicorum Græcorum Fragmenta (1889). Consult Wolf, De Iophonte Poeta (1884).
