The article offers a re-edition of a Latin stilus tablet found in 1917 at Tolsum in the Netherlands, the region inhabited in Roman times by the tribe of the Frisii, and first published as a contract of sale for an ox. The re-edition, with readings based on new techniques of digital image capture, establishes the date of the text (A.D. 29) and shows that it does not concern the sale of an ox, but is more probably the second half of a loan-note for a sum of money now lost, between a debtor whose name is lost and a creditor named Carus (or perhaps Andecarus) who was a slave of Iulia(?) Secunda, herself perhaps the wife of a tribune of Legion V named T(itus) Cassius
