The modern Latgalian literary tradition started to develop in the 18th century from vernaculars spoken by Latvians in the eastern part of Latvia. The first surviving book published in Latgalian is "Evangelia toto anno" ("Gospels for the whole year") in 1753. The first systems of orthography were borrowed from Polish and used Antiqua letters. It was very different from the German-influenced orthography, usually written in Blackletter or Gothic script, used for the Latvian language in the rest of Latvia. Many Latgalian books in late 18th and early 19th century were authored by Jesuit priests, who came from various European countries to Latgale as the north-eastern outpost of the Roman Catholic religion; their writings included religious literature, calendars and poetry.
