 Jan Długosz is best known for his "Annales seu cronici incliti regni Poloniae" ("Annals or Chronicles of the Famous Kingdom of Poland") in 12 volumes and in Latin language, covering events in southeastern Europe, but also in Western Europe, from 965 to 1480, the year he died.Długosz combined features of Medieval chronicles with elements of humanistic historiography.For writing the history of the Kingdom of Poland, Długosz also used Ruthenian (Russian) chronicles including those that did not survive to our times (among which there could have been used the Kyiv collection of chronicles of the 11th century in the Przemysl's edition around 1100 and the Przemysl episcopal collections of 1225-40).
