Konstantinas Sirvydas

Konstantinas Sirvydas (rarely referred as Konstantinas Širvydas; Latin: Constantinus Szyrwid; Polish: Konstanty Szyrwid) 1579 – 8 August 1631) was a Lithuanian religious preacher, lexicographer and one of the pioneers of Lithuanian literature from the Grand Duchy of Lithuania, at the time a confederal part of the Polish-Lithuanian Commonwealth. He was a Jesuit priest, a professor at the Academia Vilnensis and the author of, among other works, the first grammar of the Lithuanian language and the first tri-lingual dictionary in Lithuanian, Latin and Polish (1619). Famous for his eloquence, Sirvydas spent 10 years of his life preaching sermons at St. John's church in Vilnius (twice a day - once in Lithuanian, and once in Polish).

He was born in Lithuania some time between 1578 and 1581, in the village of Širvydai near Anykščiai. In 1612, he became a professor of theology at the Academia Vilnensis, the predecessor of Vilnius University. Between 1623 and 1624, he also briefly served as the deputy rector of his alma mater, after which he continued as a professor in theology, liberal arts and philosophy.
