Dathus
Dathus or Datus was Bishop of Ravenna during the late 2nd century. He was elected to succeed the previous bishop Probus I when miraculously, a dove appeared above his head.
According to Andreas Agnellus, his remains may have been kept in the Church of St. Probus in Classe, [ancient port of Ravenna|Classe], but this structure did not survive into Agnellus's day.
