Alcidamas

Alcidamas was a Greek rhetorician and Sophist of the late 5th and early 4th century BCE, a pupil of Gorgias and a rival of Isocrates. He is known especially for arguing the superiority of improvised speech over written compositions, and a surviving essay 'On the Sophists' is attributed to him. He also figures in the tradition behind the 'Contest of Homer and Hesiod.'
