One of the first Lithuanian authors who wrote in Latin was Nicolaus Hussovianus (around 1480 – after 1533). His poem ''Carmen de statura, feritate ac venatione bisontis'' (''A Song about the Appearance, Savagery and Hunting of the Bison''), published in 1523, describes the Lithuanian landscape, way of life and customs, touches on some actual political problems, and reflects the clash of paganism and Christianity. A person under the pseudonym  (around 1490 – 1560) wrote a treatise ''De moribus tartarorum, lituanorum et moscorum'' (''On the Customs of Tatars, Lithuanians and Muscovites'') in the middle of the 16th century, but it was not published until 1615. An extraordinary figure in the cultural life of Lithuania in the 16th century was the lawyer and poet of Spanish origin Petrus Roysius Maurus Alcagnicensis (around 1505 – 1571). The publicist, lawyer, and mayor of Vilnius, Augustinus Rotundus (around 1520 -1582) wrote a no longer existent history of Lithuania in Latin around the year 1560. loannes Radvanus, a humanist poet of the second half of the 16th century, wrote an epic poem imitating the Aeneid of Vergil. His ''Radivilias'', intended to become the Lithuanian national epic, was published in Vilnius in 1588.
