The Laurentian Codex was compiled in Nizhny Novgorod-Suzdal by the Nizhegorodian monk Laurentius for the Prince Dmitry Konstantinovich in 1377. The original text he used was a codex (since lost) compiled in 1305 for the Grand Prince of Vladimir, Mikhail of Tver. The account continues until 1305, but the years 898–922, 1263–83 and 1288–94 are missing for reasons unknown. The manuscript was acquired by the famous Count Musin-Pushkin in 1792 and subsequently presented to the National Library of Russia in Saint Petersburg.[citation needed]
