Chalcedon
Chalcedon ( or ;
, sometimes transliterated as "Chalkedon") was an ancient maritime town of Bithynia, in Asia Minor. It was located almost directly opposite Byzantium, south of Scutari (modern Üsküdar) and it is now a district of the city of Istanbul named Kadıköy. The name "Chalcedon" is a variant of Calchedon, found on all the coins of the town as well as in manuscripts of Herodotus's "Histories", Xenophon's "Hellenica", Arrian's "Anabasis", and other works. Except for a tower, almost no above-ground vestiges of the ancient city survive in Kadıköy today; artifacts uncovered at Altıyol and other excavation sites are on display at the Istanbul Archaeological Museum.
Byzas
When Byzas arrived to where the Sea of Marmaras meets the Sea of Bosporos, on the border of Europe and Asia, he realized the meaning of the oracle. On the Asian shore, opposite to where he was, a colony, Chalcedon, had already been established. Byzas decided that Chalcedon was the prophesied 'city of the blind', as it had not taken advantage of the European shore.
