A miracle of Saint Paraskevi the Great Martyr of Rome

In 1979 Saint Ephraim of Katounakia related the following miracle of St. Paraskevi:
Five years ago a blind man went to Koutloumousiou Monastery to venerate the skull of St. Paraskevi [part of her skull is at this monastery, and part of it is at Petraki Monastery in Athens]. She gave off an aroma and the blind man immediately could see and he hung up his glasses there.
