According to the Lavra Codex D39 the consecration of the Church or Monastery of the Archangel Michael in Skallai took place on July 25th, while the Synaxaristes of Saint Nikodemos says it was on July 26th. The location of Skallai is probably where Bebek is located today in modern Istanbul, along the European shores of the Bosphorus, and another Greek name for it was Chelai.
