Maciej Stryjkowski (also referred to as Strykowski and Strycovius;[1] c. 1547 – c. 1593) was a Polish[2] historian, writer and a poet, known as the author of Chronicle of Poland, Lithuania, Samogitia and all of Ruthenia (1582).

There he devoted his life to writing a monumental chronicle of the lands of Poland–Lithuania, eventually published in Königsberg (today Kaliningrad) in 1582.

The book, published under the title of Chronicle of Poland, Lithuania, Samogitia, and all of Ruthenia of Kiev, Moscow, Novgorod...[nb 1][4] is a classic piece of literature written in the Polish language and detailed much of the history of the Polish–Lithuanian Commonwealth and its parts from their legendary roots up to 1581.

[6][7][8] Until the 19th century, the works of Stryjkowski were considered to be the basic sources of information on early period of history of the Grand Duchy of Lithuania.

[9] It was not until the advent of modern historiography that his chronicle started to be criticised and disputed, mainly due to his favour of the magnates, lack of distinction between legends and historic accounts and his theory on the Roman origin of the Lithuanian ruling families.
