The aim of the article is to present two written traditions which are discernible in the Hungarian-Polish Chronicle. One of them is of the Hungarian and the other one of the Polish origin. The Le-genda sancti Stephani regis by Bishop Hartvich is one of them. It is also the simplest one to analyse. The text comparison shows that it could be regarded as the shorter text variant which served as the story basis for the chronicler, similarly to the text from the Seitz manuscript dated back to the second half of the 14th century. One of the variants of the now lost Gesta Ungarorum could be a source of information on the ancient history of Hungarians. One can observe traces of using a written source of the Polish origin as well. It could be a narrative form dating back to the beginning of the 13th century, in which the remnants of another, older text – possibly from the time of Bolesław II Large (the second half of the 11th century) – could be found.
