Sava. This flag has been preserved till today. With the arrival of the teachers Georgije Magarašević, Mojsije Petrović, Ignjat Jovanović and Pavel Jozef Šafarik the number of the classes was increased to six, and at the beginning of October 1819 the Serbian Orthodox's Great Grammar School in Novi Sad became a complete grammar school. First school building The first school building was next to the Orthodox Cathedral Church, at the spot of today's Platoneum. It was built by the council of Serbian Orthodox Church in 1788 for the needs of Latino-Slavic Nativity of the Mother of God School. With its beauty it attracted everyone who came to Novi Sad. Šafarik said about it:”The building of the school is something unique; I have never seen anything like that”. The first principals of the grammar school were a priest Danilo Petrović and the mayor Grigorije Janković. With the increased number of students and classes the Patronage took steps to insure the emperor's accreditation for the school. This meant that all graduated students of the school had the right to enroll any academy, lycee and university in Habsburg Monarchy without taking entrance or differential examinations. This accreditation was given to the school by Frantz I on October 26, 1818. The curriculum was made in accordance with the state regulation “Ratio educationis” which was applied to all state schools in Hungary. The grammar school had six classes until 1848, and all the subjects were taught in German, apart from religious lessons which were taught in Serbian. The following subjects were taught in the grammar school: the basis of Latin and German, Geography, Anthropology and Arithmetic, Latin with syntax, Religious Lessons, Nature Studies and Anthropology, World's History, Archeology, Physics, Logics, Rhetoric, Poetry and Ethics. The school flourished when a literary historian and a famous scientist Pavel Jozef Šafarik came to its head. In the period of 1816 to 1848 the school had seven principals, and the classes were taught by twenty-seven teachers. The best known among them were Milovan Vidaković, Pavel Jozef Šafarik, Georgije Magarasević i Jovan Hadžić. Collecting books in order to make a school library started on Šafarik's great insistence in 1819. Ceremonial opening of the library was in 1822 and until 1849 it had about 1600 books. Because of the importance of religious lessons, classes of church singing were held from the very beginning of the school. The first choir was founded
