Miraculous icon of St. Nicholas «O Streidas» (of the Oyster) from the Monastery of Stavronikita. The crack visible through the forehead of the Saint is where the oyster was imbedded, and the dried blood that flowed out is visible to this day.
On Mount Athos is in a monastery which is called Stavronikita which is dedicated to St. Nicholas. The monastery however was originally built in memory of St. John the Baptist. In the Iconoclast period, the monks threw many icons into the sea so they might not be contaminated by the hands of the Iconoclasts. One of those icons was of St. Nicholas, which is currently in the monastery of Stavroniketa and is one of the miraculous icons of Mount Athos.
