Bartol Kašić (, ; August 15, 1575 – December 28, 1650) was a Jesuit clergyman and grammarian during the Counter-Reformation, who wrote the first Illyrian grammar and translated the Bible and the Roman Rite into Illyrian (a name used for early Croatian or proto-Serbo-Croatian). Life Bartol was born in Pag, in the Republic of Venice (in modern Croatia) of his father Ivan Petar Kašić who participated in the 1571 Battle of Lepanto and mother Ivanica. In 1574 Ivan Petar Kašić married for Ivanica Bogdančić and they had a son Bartol next year. His father died when he was a small child, so he was raised by his uncle Luka Deodati Bogdančić, a priest from Pag, who taught him to read and write. He attended the municipal school in the town of Pag. After 1590 he studied at the Illyric College in Loreto near Ancona, in the Papal States (in modern Italy), managed by the Jesuits. As a gifted and industrious pupil, he was sent to further studies in Rome in 1593, where he joined the Society of Jesus in 1595. Kašić continued propaganda activities of Aleksandar Komulović after his death, being even greater Pan-Slav then Komulović was. Kašić censored and edited Komulović's 1606 work (Zrcalo od Ispovijesti). Kašić was made a priest in 1606 and served as a confessor in the St. Peter's Basilica in Rome. He lived in Dubrovnik from 1609 to 1612. In 1612/13, disguised as a merchant, he went on a mission to the Ottoman provinces of Bosnia, central Serbia and eastern Slavonia (Valpovo, Osijek, Vukovar), which he reported to the pope. From 1614 to 1618 he was the Croatian confessor in Loreto. He went on his second mission in 1618/19. In old age, he described both missions in his incomplete autobiography. His second stay in Dubrovnik lasted from 1620 to 1633. Then he returned to Rome, where he spent the rest of his life. Literary activity Already as a student, Kašić started teaching Illyrian in the Illyric Academy in Rome, which awakened his interest in Illyrian. By 1599 he made a Illyrian-Italian dictionary, one of the first Croatian dictionaries, which has been preserved as a manuscript in Dubrovnik since the 18th century. Some experts believe it is one of three dictionaries made by Kašić and that the other two are archived in Perugia and Oxford. Kašić's native dialect was Chakavian. In the 16th century, the Chakavian
