I'm planning a display on law of the ancient Western world for the case just inside the library's front door. I think I may have mentioned this before. I have printed out images of papyrus fragments of legal documents to spice things up. One is here.
That item is Cession of three slaves in Greek (P.Duk.inv.527 R) circa 200 AD.
“Papyrus cession of three minor slaves to a creditor from Oxyrhynchos, Egypt (modern name: Bahnasa). The slaves are given to the creditor in lieu of the loan and the interest. The slaves were originally bought from Hermaiskos, son of Ammonios (aged 21) through the notary office of Oxyrhynchos and from another person. The slaves will stay with the debtor until they come of age.”
