CONON of Samos, Greek astronomer and geometer (3rd cen tury B.c. ), made astronomical observations in Italy and Sicily, but settled in Alexandria. He was the friend of Archimedes, who survived him. Conon is best known in connection with the Kome Berenikes (Hair of Berenice). Berenice, the wife of Ptolemy Euergetes, had in accordance with a vow dedicated her hair in the temple of Arsinoe of Zephyrium as an offering on the safe return of her husband from his Syrian expedition. It disappeared from the temple, and was declared by Conon to have been placed among the stars. Callimachus wrote a poem on the subject, of which only a few lines are preserved, but we possess the imitation of it by Catullus. Conon wrote on astronomy in seven books, and made a list of the observations of solar eclipses recorded in Egypt. He also investigated the question of the maximum num ber of points of intersection of two conics, and of a conic and a circle. (See Apollonius, Conics, Bk. iv., Pref.)
