A 4th to 5th-century papyrus fragment from an ancient book (codex) containing portions of the story of Joseph in Egypt, specifically Genesis 41. Acquired by Coptologist Carl Schmidt, this artifact resides at the University of Erlangen and provides valuable early evidence of the Greek transmission of Genesis. An unusual physical detail is that the back side (verso) of this specific leaf precedes the front side (recto) in the natural flow of the story.

Codex Alexandrinus is one of the four great uncial codices of the Greek Bible. It contains the vast majority of the Septuagint and New Testament, and was the first of the great uncials to become accessible to modern scholars.
