The only literary evidence that supports a historical date, relating to this saint, is documented in the book Lives of the Saints, which testifies that the icon in Rhodes was discovered, around 1500 AD. Some sources support the opinion that the icon was discovered in Cyprus and not in Rhodes. A recent research paper on folklore suggests that there are two manuscripts. The first is the mention of a miracle included in the Cod. Vat. Gr. 1190 (dating from 1452 and written in Crete) and was published in the Acta Sanctorum. The second manuscript originates from Heraklion, dating from 1600-1640 (Vassilakes-Mavrakakes 1980-81, p. 226). Both of these manuscripts describe a miracle that took place in Rhodes which caused the saint's fame to spread from Rhodes to Crete.
