Little is recorded of his earthly life, except that he was a monk and ascetic on Cyprus who rose to episcopal rank, and that he was martyred during a persecution of Christians. His body rested for centuries in a church in Cyprus. Then in 806, during the reign of the Emperor Nikephoros, the Saint appeared to the church's caretaker, warned him that infidels were about to attack Cyprus, and ordered that his relics be transferred to Constantinople. Without hesitation the caretaker had the casket containing St Therapon's relics put in a ship bound for the Capital. During the journey a great storm arose, but the waters around the ship remained calm, and a sweet scent filled the ship. The caretaker opened the casket and found that it was full to overflowing of a fragrant myrrh which exuded from the holy martyr's relics. In Constantinople, a church was built over the Saint's relics, which became known as a powerful source of healing for those who approached in faith.
