Life and Martyrdom
Hyacinthus was born to pious Christian parents in Amastris, a Black Sea port of the Roman province of Pontus in the region of Paphlagonia. His life records that his given name was determined at his birth by an angelic visitation, a sign of the wonder that would mark his short life.
From an early age he was distinguished by an extraordinary faith. By tradition, when he was about three years old he petitioned God to raise a dead infant; the prayer was answered, and the restored child and Hyacinthus afterward grew up together and shared an ascetic manner of life.
His martyrdom arose from an act of religious conviction. Encountering pagans engaged in the worship of a sacred tree, he opposed the idolatry and felled the tree. The pagan community retaliated severely: his teeth were smashed out, and he was bound with rope and dragged along the ground before being thrown into prison. The holy sufferer died there of his wounds. One account names the local lord who punished him as Castrinsius and adds that he was beaten and pierced with sharp canes; the sources agree that he died in prison from the torments inflicted on him.
