“Diocletian”
He has always been one of the more interesting Roman Emperors to me, as as far as I know he is the only one to have “retired’ from the job. All others died in battle, of natural causes or were assassinated.
Some did die on the job like Augustus, Marcus Aurelius, etc. Otherwise you’re right Diocletian is unique.
There were a lot for sure.
And as under many emperors "Roman subjects including Christians were compelled to sacrifice to Roman gods" and Diocletian "purged the army of Christians, condemned Manicheans to death, and surrounded himself with public opponents of Christianity" so the Left works to compelled all to sacrifice (give up speech, associations, occupations, etc.) in the interest of self-preservation by essentially saluting the flag of Sodom.
