Saint Vitus , according to Christian legend, was a Christian saint from Sicily. He died as a martyr during the persecution of Christians by co-ruling Roman Emperors Diocletian and Maximian in 303. Vitus is counted as one of the Fourteen Holy Helpers of medieval Roman Catholicism. Saint Vitus' Day is celebrated on 15 June. In places where the Julian Calendar is used, this date coincides, in the 20th and 21st centuries, with 28 June on the Gregorian Calendar.
