[1] Fascinated by the folklore and the traditional folk songs of the former Grand Duchy of Lithuania, a confederal part of the Polish–Lithuanian Commonwealth, he recollected hundreds of them in his works.

[3] There, he made friends with many of the predecessors of Polish romanticism, among them Adam Mickiewicz, who is said to support Czeczot's early poetic writings.

Also, Czeczot became the secretary of the Philomatic Society and a friend of Ignacy Domejko, with whom he shared passion for the folklore.

[5] In 1837 he was allowed to publish his first book, the Piosnki wieśniacze znad Niemna (Folk Songs of the Neman River).

The second edition of that anthology, published in 1844 under the title of Piosnki wieśniacze znad Niemna z dołączeniem pierwotwornych w mowie słowiańsko-krewickiej (Folk Songs of the Neman River with Originals Written in Slavic-Krevich Language), was significantly expanded and included many translations of his works to what could be seen as a predecessor of the modern Belarusian language.
