In the days when the Turkish Sultan ruled in Hungary as far as Ersekujvar and Eger, the German Kaiser from Eger to the Zips country, and George Rakoczy, Prince of Transylvania, from Zips to the Szeklerland, all three of whom were perpetually fighting among themselves, sometimes two against one and sometimes all together indiscriminately, so that the inhabitants had a very lively time of it, in those days (somewhere about 1650) the learned and reverend Master David Fröhlich was the pride of the Keszmár Lyceum and Professor of Mathematics and Astronomy there.
