Cathedral School of Vilnius
The Cathedral School of Vilnius was a cathedral school attached to the Vilnius Cathedral. It is believed to be the earliest school in the Grand Duchy of Lithuania. For about a hundred years it was the only Catholic school in Vilnius. The cathedral school was merged with Vilnius Academy, established by the Jesuits in 1570.
The exact date of its establishment is unknown, but it must be sometime between the Christianization of Lithuania in 1386 and school's first mention in written sources on May 9, 1397. It was initially a primary school, evolving into a secondary school by the first half of the 15th century. Most likely the school taught trivium and quadrivium and catered to church needs educating lower clergy. Its first pupils were indigenous Christians that also knew the Lithuanian language. In 1522, Bishop John expanded the school to three classes and introduced courses in rhetoric, dialectics, classical literature, arithmetic, music. The students studied Distichs of Cato and Ars grammatica by Aelius Donatus. In 1539, the school had twelve boys who sang in a church choir and twenty boys who served as altar boys. During its existence, the school prepared over 100 students who later pursued academic careers at the Jagiellonian University in Kraków.
