The following miracle was witnessed by many. It took place before the wonderworking Panagia Prousiotissa Icon on Friday the 24th of August in the year 1928, at six o'clock in the evening. A 38 year old woman, Katherine Niphoropoulos, from the village of Riolo Achaia in the province of Patras, had been suffering from demonic possession for eight years. After visiting one physician after another and finding no cure for what afflicted her, her family and acquaintances had her then begin to make pilgrimages to many monasteries as a last refuge and hope. Finally she arrived at the Monastery of Prousos in Karpenisi.
At Prousos Monastery, Katherine's family and acquaintances requested that the priest, Father Cyril, read the exorcism prayers over her before the wonderworking icon of Panagia Prousiotissa. As he proceeded, Katherine cried out with a loud and mighty voice, though she was unaware of what she was saying: "O Virgin, I swear, I am going!" She repeated this over and over again. Katherine, meanwhile, was lying down on the stairs while the priest continued to read the prayers over her. At one point her head slipped from the step. She would open her mouth from time to time. Her eyes appeared cloudy and perplexed. Her arms were outstretched as though crucified. Katherine then gazed toward the holy icons. She stopped breathing. It appeared she was about to die. Then she closed her eyes as if she indeed died.
