Career
As a boy, he was appointed to serve as an assistant to the chamberlain to the Emperor Trajan. When he was denounced as a Christian, Hyacinth proclaimed his faith. As a result, he was imprisoned and underwent numerous scourgings and tortures.
Thus, he starved to death in 108 AD, dying at the age of twelve.
Just before his death, legend says, his jailers saw him being comforted by angels, who bestowed a crown on him. Hyacinthus died in the city of Rome.
Later, the saint’s relics were transferred to Caesarea. A body identified as his is preserved and venerated in the abbey church of the former Cistercian Abbey of Fürstenfeld, of which the church is the only surviving structure.
He is not to be confused with the third-century martyr Hyacinth or the medieval Polish Dominican saint Hyacinth of Poland.
