Quote:has no surviving Roman literature written about him!
You discount the contemporary writings of Philo of Alexandria and the shortly later writings of Josephus but technically you are correct. Roman writers saw no need to mention a lowly praefect of a shithole outpost like Judaea.
Josephus gives us the whole list of Roman praefects of Judaea:
Coponius, Marcus Ambivius, Annius Rufus, Valerius Gratus and Pontius Pilate. He also tells us that Pilate's successor was an officer named Marcellus put in command by then-governor Lucius Vitellius Veteris. So what. All these men issued coins and were known to archaeologists. The rather battered Pilate inscription is seriously overrated by xtians who think...as they think with all such things...that it "proves" something. It doesn't. Pilate was already well-attested in the record.
