P.Eleph. 1 (310 ΒCΕ) is the earliest dated Greek papyrus from Egypt. The contract concerns the marriage of Herakleides to Demetria, and it was drawn up as a double document. Even if the same scribe wrote both texts, the upper document (scriptura interior) was written more carefully than the lower one (scriptura exterior). In both texts, the scribe made some palaeographic interventions, some of which were already noticed in the first edition. A palaeographic re-examination based on a digital image allows to discover further corrections made by the scribe and sheds light on his writing practice.
