The Novgorod Fourth Chronicle (Russian: Новгородская четвёртая летопись, romanized: Novgorodskaya chetvertaya letopis'[1]) is a Rus' chronicle of the 15th century.
[1] It is traditionally called "Fourth" according to the order of the modern publication of Novgorod chronicles, rather than chronologically.
[citation needed] Together with the Sofia First Chronicle, it is believed that it is derived from a common source.
Russian philologist Aleksey Shakhmatov tentatively called it the Novgorodsko-Sofiysky Svod (Novgorod-Sofia Corpus) and initially dated it to 1448,[1] but later revised his opinion to the 1430s.
[citation needed] Some Russian philologists shared his opinion, while others attribute the common source to the 1418 Corpus of Photius, Metropolitan of Moscow.
