Scylax of Caryanda
Scylax Of Caryanda, ancient Greek explorer from Caria. He lived in 6th century BC.
In about 515 BC Scylax was sent by the Persian king Darius I of Persia to explore the course of the Indus River. Scylax and his companions sailed down the river to the east and the rising of the sun, till they reached the sea. From whence they sailed westward through the Indian Ocean to the Red Sea, performing the whole voyage and returning in thirty months.
Scylax is mentioned by Strabo as an ancient writer. The Periplus of Pseudo-Scylax which dates from the 3rd century AD is a compilation which seems to have been named in his honour.
See Herodotus 4.44
