Firmilian was the Roman governor of the Iudaea Province, during the third Late Roman Period of the Roman rule over the region.
He was the third of a succession of governors (Flavianus, Urbanus, and Firmilian) who enforced the Diocletian Persecution at Caesarea, the province's capital, which lasted for twelve years.
[1] He is commonly referred as cruel and sadistic[1][2][3][4] for torturing and killing many Christians and being heartless even to his close allies.
[3][4] He was beheaded for his crimes around 310 AD, by the emperor Maximinus’s order, as his predecessor Urbanus had been two years before.
