St. Castorius is one of the “four crowned martyrs”. They were tortured and executed during the reign of Diocletian during the rule of Diocletian in Hungary. St. Castorius and the other “crowned martyrs” were commissioned by Diocletian as carvers. Diocletian was impressed by their carvings and he requested them to carve a statue of Aesculapius, a Greek god. They refused to do it as they were Christians. They also refused to sacrifice to the gods and because of this they were imprisoned. They were also falsely accused of being involved in the death of one of Diocletian’s officers.
St. Castorius died around 287 A.D.. He is the patron saint of sculptors.
