Ivan Belostenec (born in Varazdin, 1594-1675), who wrote “Gazophylacium seu Latino-Illyricorum onomatum aerarium” published in Zagreb in 1740. It provides a lexical wealth of three Croatian dialects: kajkavian, stokavian and chakavian. This monumental book which has 2000 pages and more than 40,000 words is important not only for Croatian but also for European cultural history: at that time a similar dictionary existed only in Florence, prepared under uncomparably better conditions. Belostenec was a Paulist monk in Lepoglava, who spent part of his life in Croatian south, including Istria. This is also reflected in his dictionary. An incomplete copy of his book Deset propovjedi o Euharistiji (published in Graz in 1672) is held in the University Library of Budapest.
