About 450 AD a Byzantine soldier, called Leon, was in a forest, when he saw a blind man in front of him asking for some water to quench. Leo was willing to search and bring him water. So, he was searching in the forest for a long time to find some source of water but in vain. So, he returned sad.
Suddenly, he heard a woman's voice telling him: "No need, Leo, to worry, to be angry, to be sad, the water is beside you". And after a while he listened to the unknown voice commanding him: "Leo King, take this water and let the blind man drink and quench, and one more thing, smear his eyes with this and you will soon understand, who is the voice that is talking to you". That's what Leo did, and then the blind man found his light. At the same time, Leo's eyes were opened, and he realized that the voice that spoke to him was of the Virgin Mary and that the great miracle of the healing of the blind was due to Ηer.
