3. Of Cyzicus, a geographer, who went from his native place to Egypt, and was employed by Ptolemy Evergetes and his wife Cleopatra in voyages to India; but afterwards, being robbed of all his property by Ptolemy Lathyrus, he sailed away down the Red Sea, and at last arrived at Gades. He afterwards made attempts to circumnavigate Africa in the opposite direction, but without success. (Strab. ii. pp. 98–100; Plin. ii. 67.) He must have lived about B.C. 130.[P. S.]
