Chester Beatty Papyri

The Chester Beatty Biblical Papyri or simply the Chester Beatty Papyri are a group of early papyrus manuscripts of biblical texts. The manuscripts are in Greek and are of Christian origin. There are eleven manuscripts in the group, seven consisting of portions of Old Testament books, three consisting of portions of the New Testament (Gregory-Aland no. P45, P46, and P47), and one consisting of portions of the Book of Enoch and an unidentified Christian homily. Most are dated to the 3rd century. They are housed in part at the Chester Beatty Library in Dublin, Ireland, and in part at the University of Michigan, among a few other locations.

The papyri were most likely first obtained by illegal antiquity traders. Because of this, the exact circumstances of the find are not clear. One account is that the manuscripts were in jars in a Coptic graveyard near the ruins of the ancient city of Aphroditopolis. Other theories have proposed that the collection was found near the Fayum instead of Aphroditopolis, or that the location was a Christian church or monastery near instead of a graveyard. Most of the papyri were bought from a dealer by Alfred Chester Beatty, after whom the manuscripts are named, although some leaves and fragments were acquired by the University of Michigan and a few other collectors and institutions.

The papyri were first announced on November 19, 1931, although more leaves would be acquired over the next decade. Frederic G. Kenyon, in an 8 volume work that spanned 1933-58, published the manuscripts in The Chester Beatty Biblical Papyri: Descriptions and Texts of Twelve Manuscripts on Papyrus of the Greek Bible. The papyri are usually cataloged as P. Chester Beatty followed by a corresponding Roman numeral between I-XII, one for each manuscript.

The term "Chester Beatty Papyri" can also generally refer to the collection of manuscripts that Alfred Chester Beatty acquired over his lifetime, which include non-Biblical papyri such as the Chester Beatty Medical Papyrus.
