Ostromir Gospels

The Ostromir Gospels (Russian: Остромирово Евангелие; also known as the Ostromir Gospel or the Ostromir Lectionary) are the oldest dated book of Kievan Rus' and the oldest dated Russian manuscript. Archaeologists have dated the Novgorod Codex, a wax writing tablet with excerpts from the Psalms, discovered in 2000, to an earlier time range, but unlike the Ostromir Gospels, it does not contain an explicit date. The book is currently held in the National Library of Russia.

The Ostromir Gospels were created in 1056 or 1057 (the year 6564 in the Byzantine calendar) by the deacon Gregory for his patron Ostromir, the posadnik of Novgorod, probably as a gift for a monastery.
