Both Stephen Runciman and Franz Babinger note this date was the 200th anniversary of Michael VIII Palaiologos' recapture of Constantinople from the Latin Empire.[44] Mehmed made a detailed inspection of the city, its defenses and its inhabitants, according to Miller, who then quotes Kritoboulos, "He [Mehmed] ascended to the citadel and the palace, and saw and admired the security of the one and the buildings and splendour of the other, and in every way he judged the city worthy of note."[45] Mehmed converted the Panagia Chrysokephalos cathedral in the center of the city into Fatih Mosque, and in the church of Saint Eugenios he said his first prayer, thus giving the building its later name, Yeni Cuma ("New Friday").[45]
