The Oxyrhynchus Papyri are a group of manuscripts discovered during the late nineteenth and early twentieth centuries by papyrologists Bernard Pyne Grenfell and Arthur Surridge Hunt at an ancient rubbish dump near Oxyrhynchus in Egypt (28°32′N 30°40′E / 28.533°N 30.667°E, modern el-Bahnasa). The manuscripts date from the time of the Ptolemaic (3rd century BC) and Roman periods of Egyptian history (from 32 BC to the Muslim conquest of Egypt in 640 AD).
