Novgorod Fourth Chronicle
The Novgorod Fourth Chronicle is a Russian chronicle of 15th century. It is traditionally called "Fourth" according to the order of the modern publication of Novgorod chronicles, rather than chronologically.
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 and initially dated it by 1448, but later revised his opinion to 1430s. Some Russian philologists shared his opinion, while others attribute the common source to the 1418 Corpus of Photius, Metropolitan of Moscow.
