A short private letter on an ostracon from Serapion to his father, also named Serapion, found at the quarry site of Mons Claudianus in the mid-2nd century AD. He asks his father to buy a papyrus roll and pay the teacher Didymos to copy a prose text for him.
In English machine translation
Serapion to Serapion his father, many greetings. Before all else I pray for your safety. I felt compelled to greet you by a little letter.
You will do well, if you buy the papyrus roll, to go to Didymos the teacher and give him money (bronze) so that he may copy out for me a prose text. For the rest, then, do not do otherwise.
"Pezos logos" means prose, as opposed to verse; the kathegetes Didymos was a teacher. "Chalkos" literally means bronze, i.e. copper coinage as payment.
