Its left bank, however, is looked down upon by the port of Athyras and Selymbria, and Constantinople, the ancient Byzantium, a colony of the Athenians,[*](According to the Eusebian Chronicle, Byzantium was founded by the Megarians in Olymp. 30, 2 (600 B.C.); so also Herodotus (iv. 144), who, however, gives the date as Olym. 26, 2 (616 B.C.). Justin (ix. 1, 2 f.) names the Spartans; Velleius (ii. 7, 7) the Milesians, who were descended from the Athenians. The founding was probably attributed to the Athenians from the time of Constantine from motives of pride) and the promontory Ceras, which bears a tower built high and giving light to ships[*](A pharos, or lighthouse) ; therefore a very cold wind which often blows from that quarter is called Ceratas.
