Novgorod Fourth Chronicle

The Novgorod Fourth Chronicle (Russian: Новгородская четвёртая летопись, romanized: Novgorodskaya chetvertaya letopis'^[1]) is a Rus' chronicle of the 15th century.^[1] It is scholarly abbreviated as N4.^[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.^{[citation needed]}
