Attius Insteius Tertullus
Attius Insteius Tertullus was a Roman urban prefect.
He was a descendant of Lucius Insteius Tertullus, who was sodalis Augustalis in 214. Having risen to become a senator, Tertullus served as consul suffect before his appointments as proconsul of Africa and praefectus urbi in 307–308. He was honoured by an inscription from Patavium, and was probably the father of Attius Insteius Tertullus Populonius, imperial governor of Apulia and Calabria.
