University of Vilnius and spent most of his productive years in Lithuania - Vilnius and Kražiai. His European fame came from his first collection of poetry, Lyricorum libri tres (Three Books of Lyrics, 1625). In his book Dii gentium (Gods of The Nations,1627) along with Roman deities he described Lithuanian mythology. Adam Schröter (1525–1572) wrote a poem in Latin devoted to river Nemunas De fluvio Memela Lithuaniae carmen elegiacum (Elegic songs about Lithuanian river Nemunas). 17th-century Lithuanian scholars also wrote in Latin, which was the common scholarly language in Catholic Europe: Kazimieras Kojelavičius-Vijūkas and Žygimantas Liauksminas are known for their Latin writings in theology, rhetorics and music. Albertas Kojalavičius-Vijūkas wrote the first printed Lithuanian history in two volumes, Historiae Lituanae (1650, 1669). Kazimieras Kojelavičius-Vijūkas was a prolific writer - his legacy counts more than 20 books in Latin. Maciej Stryjkowski and Augustinus Rotundus were strong proponents of using Latin as the official language of Grand Duchy of Lithuania because they thought that Lithuanian language was just a vernacular language which had developed from Latin. Their belief was based on grammatical similarities between Lithuanian and Latin. Universitas lingvarum Litvaniae, written in Latin and published in Vilnius, 1737, is the oldest surviving grammar of the Lithuanian language published in the territory of the Grand Duchy of Lithuania. Latin books of Lithuanian authors were published in Vilnius, Cracow and Riga. Only in the 16th century, 158 Latin books were published in Vilnius. Researches count 374 books published in the Grand Duchy of Lithuania, or written by citizens of GDL and published abroad in the 15th-16th centuries. Although the first printing press was established in the Grand Duchy of Lithuania in 1522, in Vilnius, the first who established a printing press in a City of London in 1480 was Lithuanian John Lettou. Lithuanian language Lithuanian scholars Abraomas Kulvietis (about 1510 – 1545), Stanislovas Rapolionis (1485–1545) were the very first authors to write in the Lithuanian language. Lithuanian literary works in the Lithuanian language were first published in the 16th century. In 1547, Martynas Mažvydas (about 1520–1563) compiled and published the first printed Lithuanian book, The Simple Words of Catechism, which marks the beginning of printed Lithuanian literature. He was followed by Mikalojus Daukša (1527–1613) in Lithuania Propria with his Catechism, or Education Obligatory to Every Christian. In the 16th and 17th centuries, Lithuanian literature was primarily religious. During the Reformation, Catholic and Calvinist supporters
