context_page_description: The Kontoskalion, also known as Harbour of Julian, Portus Novus, or Harbour of Sophia, and in Ottoman times as Kadırga Limanı was a harbour in the city of Constantinople, active from the 6th century until the early Ottoman period. In the literature it has been known under several names, and the sources about it are often contradictory.
context_section_description: Already during the reign of Constantine the Great (r. 306–337) the site of the later harbour was used as a landing stage. In 362, during his short stay in the capital, Emperor Julian (r. 361-363) built on the Propontis shore a harbour named Portus Novus ("New Port") or Portus Iulianus (Greek: Λιμὴν τοῦ Ἰουλιανοῦ): at the same time he erected in front of it a crescent-shaped building named Sigma or Porticus Semirotunda. This decision was taken despite the many problems which affected the location: each port along the Marmara shore was undefended against the fierce storms caused by the intermittent southwest wind, the Lodos; these brought much sand into the basin, making necessary a periodic and expensive dredging; moreover, the heavy rains provoked erosion from the hills which caused silting too. On the other hand, the building of a harbour on the south shore was necessary to supply the western and southern regions of the city, too far from the Golden Horn.
  The problems of this area were compounded by repeated urban fires, the first fire having occurred at the end of the 4th century partially destroying the area. In the 6th century, Emperor Anastasius I (r. 491-518) emptied the basin using hydraulic machines, built a mole and dredged the sandy substrate. Later, possibly under Justinian (r. 527–565), part of the traffic of the Neorion port, the first harbour built in the city, lying on the Golden Horn, was moved to the new harbour. After damage by another fire in 561, his successor Justin II (r. 565–578) in around 575 commissioned important works, dredging the ground again and enlarging the basin: the works were directed by two high officials, the praepositus Narses and the protovestiarios Troilos. In front of the enlarged harbour, renamed "Port of Sophia" (Greek: Λιμὴν τῆς Σοφίας) after Justin's empress, were erected four statues, representing Justin, Sophia, their daughter Arabia and Narses.
  At the end of the century, the harbour also acquired a military function, which it did not lose until the end, becoming a base of the Byzantine navy. Emperor Philippikos Bardanes (r. 711–713) removed two of the statues adorning the Kontoskalion, since they bore prophetic inscriptions which he considered unfavorable. During his reign, Emperor Theophilos (r. 829–842) had an arsenal built near the harbour, in proximity of the Porta Leonis (the Ottoman Çatladı Kapı); it comprised a shipyard and armories. Between the 9th and the 11th century, the port remained operational: in that period, the writers of the Patria Constantinopolitanae began to refer to it also as Kontoskalion, which remains the modern Greek denomination of the quarter lying to its west, known in Turkish as Kumkapı.
  After the end of the Latin Empire, the harbour appears in several sources under the name Kontoskelion, causing confusion among modern scholars. According to the Patria, this denomination is a patronymic referring to a certain Agallianos, a Byzantine tourmarches (senior army officer) nicknamed Kontoskeles because of his short legs, but the German scholar Albrecht Berger rejects this as a mistake by the Patria authors, due to the different etymology of the two words: "Kontoskalion" means "short step or wharf". Some authors, like Raymond Janin, have proposed that the name Kontoskelion (Greek: πρὸς τὸ Βλάγκα Κοντοσκέλιον) could refer to another harbour placed 150 m west of the Julian/Sophia harbour, nearer to the Vlanga area, but this interpretation should be disregarded, since it is certain that the Kontoskalion was the only port in use on the Marmara Sea until the 15th century. In that period, the harbour maintained its important function: during the Palaiologos dynasty, Emperor Michael VIII (r. 1259–1282) protected it with an ashlar wall and a chain, while his successor Andronikos II (r. 1282–1328) made the harbour deeper and closed its entrance with iron gates, protecting the ships from the storms that come with the Lodos. The harbour was attested in an encomium of Emperor John VIII (r. 1425–1448) written in 1427. From it we know that John VIII ordered repairs
