Manichaean Psalm Book
The Manichaean Psalm Book or Manichaean Psalter is a Manichaean text written in Coptic. It is believed to have been compiled in the late 3rd century or the mid-4th century. Excavated in 1929 as part of the Medinet Madi library, the Psalm Book is believed to contain remnants of some of the earliest extant Manichaean literature.
