Pliny states that Chalcedon was first named Procerastis, a name which may be derived from a point of land near it: then it was named Colpusa, from the harbour probably; and finally Caecorum Oppidum, or the town of the blind.
Megarian colony
Chalcedon originated as a
Megarian colony in 685 BC. The colonists from Megara settled on a site that was viewed in antiquity as so obviously inferior to that visible on the opposite shore of the Bosphorus (with its small settlements of Lygos and Semistra on
Seraglio Point), that the 6th-century BC Persian general
Megabazus allegedly remarked that Chalcedon's founders must have been blind. Indeed, Strabo and Pliny relate that the
oracle of Apollo told the Athenians and Megarians who founded Byzantium in 657 BC to build their city "opposite to the blind", and that they interpreted "the blind" to mean Chalcedon, the "City of the Blind".
Nevertheless, trade thrived in Chalcedon; the town flourished and built many temples, including one to
