Saint Nestor the Chronicler, of the Kiev Caves, Near Caves was born at Kiev in 1050. He came to Saint Theodosius (May 3) as a young man, and became a novice. Saint Nestor took monastic tonsure under the successor to Saint Theodosius, the igumen Stephen, and under him was ordained a hierodeacon.
The chief work in the life of Saint Nestor was compiling in the years 1112-1113 The Russian Primary Chronicle. “Here is the account of years past, how the Russian land came to be, who was the first prince at Kiev and how the Russian land is arrayed.” The very first line written by Saint Nestor set forth his purpose. Saint Nestor used an extraordinarily wide circle of sources: prior Russian chronicles and sayings, monastery records, the Byzantine Chronicles of John Malalos and George Amartolos, various historical collections, the accounts of the boyar-Elder Ivan Vyshatich and of tradesmen and soldiers, of journeymen and of those who knew. He drew them together with a unified and strict ecclesiastical point of view. This permitted him to write his history of Russia as an inclusive part of world history, the history of the salvation of the human race.
Saint Nestor died around the year 1114, having left to the other monastic chroniclers of the Kiev Caves the continuation of his great work.
