Laurentian chronicle
Nicholas Zharkikh
Laurentian chronicle leaded to 1304. This unique parchment manuscript rewritten (edited) in 1377. It is believed that it is rewritten from a Vladimir chronicle of 1304, but this copy can hardly be considered mechanical. For example, other chronicle, depending on the Vladimir chronicle of 1304 contain a more full text description of the capture of Vladimir by Tatars (Article of 6745); only in Laurentian chronicle in Article 6771 placed the beginning of a great informative story about Prince Alexander. This story has no end by defect in Laurentian chronicle, and was not preserved in any other chronicles, so it is likely Vladimir chronicle of 1304 did not contain this story.
Full text of excerpts from this chronicle available in ukrainian / russian versions of article.
