Vitus was a Christian martyr from Sicily who lived during the late 3rd or early 4th century. According to hagiographical traditions, he was a young boy who remained faithful to his religion despite intense persecution under the Emperor Diocletian. He is recognized as a thaumaturge, a wonderworker, and one of the Fourteen Holy Helpers. His veneration spread widely across Europe, particularly in Slavic lands and Germany, where he is celebrated on 15 June.
