In 1818, in the Polish-language "" (Wilno Weekly), he published his first poem, ""Zima miejska"" ("City Winter"). The next few years would see a maturing of his style from sentimentalism/neoclassicism to romanticism, first in his poetry anthologies published in Vilnius in 1822 and 1823; these anthologies included the poem ""Grażyna"" and the first-published parts (II and IV) of his major work, "Dziady" ("Forefathers' Eve"). By 1820 he had already finished another major romantic poem, ""Oda do młodości"" ("Ode to Youth"), but it was considered to be too patriotic and revolutionary for publication and would not appear officially for many years.
