CONON, of Samos, a mathematician and astronomer, who flourished during the reigns of Ptolemy Philadelphus and Euergetes. He was the inventor of the curve called afterwards from its more famous expounder the spiral of Archimedes, and is mentioned in terms of admiration by the Syracusan mathematicians. None of his treatises are ex-
tant. There is also a grammarian of the same name who flourished in the age of Augustus, and wrote a work on the mythical period of the early colonies.
