It's a safe bet that the writer didn't receive a classical education. Adrian is a form of Hadrian, the name of one of the Roman Empire's "five good emperors" and is a name frequently found among early Christian churchmen.
Hadrian’s mausoleum is a large round structure near the Tiber, on the same side as the Vatican. The Renaissance popes used it as a fortress and had an underground passageway so they could get there from St. Peter’s in an emergency.
The Emperor Hadrian was an anti-Semitic fag.
“The term Five Good Emperors was coined by the political philosopher Niccolo Machiavelli in 1503.”

Seeing as how Hadrian (rot his bones!) came about as close to extirpating Judaism from the earth as has ever been done by anyone, and his turning Jerusalem into a pagan Roman city, that certainly doesn't speak well of the early chrstians.
