Papyrus Oxyrhynchus III 466 is a fragmentary 2nd-century CE Greek manuscript containing wrestling instructions, including descriptions of grips, holds, and techniques. Each sequence concludes with the command "plexon" (tangle or fight it out). Discovered at an ancient rubbish dump near Oxyrhynchus, Egypt, by Bernard Grenfell and Arthur Hunt, and published in 1903, it constitutes the oldest surviving European martial arts manual. The original resides at Columbia University's Rare Book and Manuscript Library.
