Константинопольдегі Блакерна ауданының тарихы

Constantinople quarter
Blachernae was a suburb in the northwestern section of Constantinople, the capital city of the Byzantine Empire. It is the site of a water source and a number of prominent churches were built there, most notably the great Church of St. Mary of Blachernae (Panagia Blacherniotissa), built by Empress Pulcheria in c. 450, expanded by Emperor Leo I (r. 457–474) and renovated by Emperor Justinian I (r. 527–565) in the 6th century.

The Romanian philologist Ilie Gherghel wrote a study about Blachernae and concluded that it possibly derived from the name of a Vlach. (sometimes written as Blach or Blasi) Gherghel compared data from old historians like Genesios and from the Greek lexicon Suidas and mentioned the existence of a small colony of Vlachs in the area of today Blachernae. Similar opinions were sustained by Lisseanu. The name Blachernae appeared in a work of Theophanes the Confessor in connection with a revolt of Flavius Vitalianus against Emperor Anastasius I in 513. It is important to note, however, that Skarlatos Byzantios, in his influential work Constantinople Volume I, mentions the Greek tradition that the district was named after the fish species Lakernai, which the locals fished there in large quantities and called Blachernai. According to Ilie Gherghel, the word Vlach became known in the Germanic and Slavic world through the Vikings that came in contact with the Byzantine Empire. The Byzantine origin of the word Vlach is supported by the historian Stelian Brezeanu who considers that one of the first accounts about Romanians south of the Danube, referred to by the name vlachorynchini (the Vlachs near the Rynchos river), is present in a historical account about the Kastamonitou Monastery which was written in the 17th century but based on a 9th century Byzantine source.

The quarter is recorded as regio XIV in the early 5th century Notitia Urbis Constantinopolitanae, where it is recorded as being enclosed by a wall of its own. The quarter was connected to the city proper at the construction of the Theodosian Walls, but the Church of St. Mary remained outside of the walls until 627, when Emperor Heraclius (r. 610–641) built another wall to enclose it.

The historic Blachernae area is in the present day Istanbul quarter known as Ayvansaray. The sacred spring, associated with the Virgin Mary, can still be visited today; in Turkish it is named Ayazma, a name derived from the Greek term hagiasma (Greek: ἁγίασμα), meaning "holy water".
