Patriarch Constantius, _Ancient and Modern Consple._, pp. 85, 86. The
  church was erected or restored by Maria, the natural daughter of
  Michael Palæologus, upon her return to Constantinople, after the death
  of her husband, the Khan of the Mongols. It has remained in the
  possession of the Greek community, in virtue of a firman of Mehemet
  the Conqueror, who presented the church to Christodoulos, the
  architect of the mosque erected by the Sultan on the Fifth Hill (_Acta
  Patriarchatus CP._, vol. i. p. 321, year 1351).

  _Chroniques Græco-Romaines_, pp. 96, 97. Dr. Mordtmann thinks that
  this point is referred to also in the Treaty of Michael Palæologus
  with the Venetians in 1265, when that emperor allowed the Venetians to
  occupy any point from the old Arsenal to Pegæ (ἀπὸ τῆς παλαιᾶς
  ἐξαρτύσις μέχρι καὶ τῶν Πηγῶν). The passage is ambiguous, for there
  was an old arsenal and a suburb Pegæ on the northern side of the
  Golden Horn, and the concession was outside the city.

  was the Church of St. Conon (_Paschal Chron._, p. 721), memorable in
  the Sedition of the Nika, as the church of the monks who rescued two
  of the seven rioters condemned to death from the hands of the clumsy
  executioner, and carried them across the Golden Horn in a boat to the
  Church of St. Laurentius for sanctuary (Malalas, p. 473).
