“ CONON, Greek astronomer and geometrician, flourished at Samos in the 3rd century B.C. He was the friend of Archimedes, who survived him. Conon is best known in connexion with the Coma Berenices (Hair of Berenice) . Berenice, the wife of Ptolemy Euergetes, had dedicated her hair in the temple of Arsinoë of Zephyrium (Aphrodite Zephyritis) as an offering to secure 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. ”
