The Pahlavi Psalter is the name given to a 12-page non-contiguous section of a Middle Persian translation of a Syriac version of the Book of Psalms.
The Pahlavi Psalter was discovered in 1905 by the second German Turpan expedition under Albert von Le Coq.
The translation itself dates to not before the mid-6th century since it reflects liturgical additions to the Syriac original by Mar Aba I, who was Patriarch of the Church of the East c. 540–552.
More recently however, another sample of the writing was discovered in the inscriptions on a bronze processional cross found at Herat (in present-day Afghanistan).
Due to the dearth of comparable material, some words and phrases in both sources remain undeciphered.
