an ail-Russian chronicle codex of the late 15th and early 16th centuries, preserved in a single manuscript copy. In the 17th century, the chronicle belonged to the proofreader of the Moscow Pechatnyi Dvor (State Printing Office), Nikifor Simeonov, after whom it was named.
The Simeonov Chronicle sets forth events from 1177 through 1493. The section from 1177 through 1390 is similar to the text of the Troitsa Chronicle, which burned in the Moscow fire of 1812, and the section from 1390 through 1412 is similar to the text of the Rogozhskii Chronicle. The text covering the period from 1410 through 1479 corresponds with the text of the Moscow codex of 1479. The last section of the Simeonov Chronicle, covering the period from 1480 through 1493, was derived from the official codex of the Muscovite grand principality. The chronicle’s unique information, especially on Muscovite 14th-century history, makes it a very valuable historical source. The Simeonov Chronicle is published in Complete Collection of Russian Chronicles, vol. 18 (St. Petersburg, 1913).
