Codex Bodmer III, is a Coptic uncial manuscript of the fourth Gospel, and the first four chapters of Genesis, dated palaeographically to the 4th century.
Originally codex contained 239 pages, but the first 22 are damaged and only small fragments have survived.
The Gospel of John is followed by the text of Book of Genesis (1:1-4:2) with page numbers beginning with α in a new series.
Because its text is different from later Bohairic manuscript (from 12th century and later) it was called to be the proto-Bohairic version (Papyrus Bodmer III).
The manuscript was discovered in Upper Egypt and purchased by John M. Bodmer of Geneva.
