In the 250 years that separate the Neronian persecution in 64 CE from the conversion of Constantine to Christianity, c. 312, Christianity was an illegal and suspect religion whose members were subject to arrest, condemnation and, in many cases, death. During the last half of the second century, instinctive popular anger against the Christians generated the violent, sporadic persecutions recorded by Eusebius. The Jews are now less prominent, though at this time the Platonist critic Celsus still regarded the Christians as apostates from Judaism. In Alexandria, where Dionysius, bishop through two persecutions, was an eyewitness, we find the same conflict but without equally tragic results. His account of his interrogation by the deputy prefect, Aemilian, is preserved by Eusebius. In Palestine, there were forty-seven executions recorded by Eusebius in his Martyrs of Palestine, most for provoking the authorities. The majority of recalcitrant Christians, however, were sent to work in the mines of Egypt.
