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.
Joseph Lebon
He is best known for his immense work devoted to the reception of the Council of Chalcedon in the Syriac and Armenian domains. His 1909 thesis devoted to Monophysite resistance to the Chalcedonian definition or horos centred on the writings of Severus of Antioch and the influence of Cyril of Alexandria. Editions of the surviving Syriac translations of Severus in the Corpus Scriptorum Christianorum Orientalium and ground-breaking articles in Le Muséon followed at regular intervals. The climax of Lebon's work in this area consisted in a contribution to the commemorative volumes for the fifteen hundredth anniversary of the Council (Das Konzil von Chalkedon I-III, eds. Alois Grillmeier, Heinrich Bacht, Wuerzburg 1951-1954). He also edited an early Sources Chrétiennes volume of Athanasius' Letter to Serapion.
