After
Theonus,
Peter is ordained the 21st bishop of the
Church of Alexandria, who later in the ninth year of the
persecution accomplished a glorious martyrdom.
Diocletian and
Maximian Augusti celebrated a triumph at Rome with notable pomp. Before their chariot went the wife, sisters and children of
Narses, and all the booty,
which they had looted from the
Parthians.
In a horrible earthquake at Tyre and
Sidon, many edifices were ruined and an immense number of people were crushed.
In the nineteenth year of Diocletian, during the month of March, in the days of Easter, the churches were destroyed. However in the 4th year of the persecution,
Constantine began to reign.
