EUCLID'S ELEMENTS AND THE OXYRHYNCHUS PAPYRI OF SOUTHERN EGYPT

https://en.wikipedia.org/wiki/Oxyrhynchus_Papyri "Also found were the oldest and most complete diagrams from Euclid's Elements. Fragments of Euclid discovered lead to a re-evaluation of the accuracy of ancient sources for The Elements, revealing that the version of Theon of Alexandria has more authority than previously believed; according to Thomas Little Heath." This is "Euclid's Element's" find in southern Egypt not in Greece. https://en.wikipedia.org/wiki/Euclid%27s_Elements
