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.
Chalaeum
Chalaeum or Chalaion () or Chaleion (Χάλειον) or Chaleos (Χαλεώς) was an ancient town on the coast of the Locri Ozolae, near the borders of Phocis. Pliny the Elder erroneously calls it a town of Phocis. During the Peloponnesian War, the town was one of several that were forced to provide hostages to the Lacedaemonian army in 426 BCE. Several inscriptions mentioning the town have been found. One of them refers to an agreement of "sympoliteia" signed with the bordering city of Tritaea, according to which the inhabitants of each of the towns could own or lease land in the neighboring one.
