The Slavic typography community has created and published the Slavonic
Ostrog font for free access. It can be downloaded in the versions TrueType (TTF), “long” TrueType (TTF), Type1 and “long” Type1.

The font was developed on the basis of old printed editions of the city of Vilna and Ostrog of the second half of the XVI century. The creator of the font is supposedly
Peter Mstislavets , a Belarusian typographer who came to Moscow and helped the Russian first printer Ivan Fedorov to print his first book. Then Mstislavets returned to Belarus (GDL) and built his own printing press there. In Belarus, printing was known for half a century before, so that the printing house was not the first.

As printers typographers report, the Ostrog font is available for free free use, with the exception of contexts that are fundamentally incompatible with Orthodoxy or seriously contradict the norms of Christian morality.
