According to Poseidonius, later reported in Strabo's "Geography", the monsoon wind system of the Indian Ocean was first sailed by Eudoxus of Cyzicus in 118 or 116 BC. Poseidonius said a shipwrecked sailor from India had been rescued in the Red Sea and taken to Ptolemy VIII in Alexandria. The unnamed Indian offered to guide Greek navigators to India. Ptolemy appointed Eudoxus of Cyzicus, who made two voyages from Egypt to India. The first, in 118 BC, was guided by the Indian sailor. After Eudoxus returned with a cargo of aromatics and precious stones a second voyage was undertaken in 116 BC. Eudoxus navigated the second voyage, sailing without a guide.
