Zlatoust IeUcs by Vladislav Dorosh is a free ornamental Cyrillic display font with a distinctly church-Slavonic mood. The letters rise into narrow, icon-like forms, mixing tall vertical shapes with small crossbars, hooked accents, and crown-like tops that make the set feel ceremonial rather than merely decorative.
It suits liturgical book covers, museum graphics, historical posters, folk festival branding, title cards, and monograms where that old manuscript atmosphere needs to come through fast. As a free font, it works best in short lines and featured initials, because the compressed proportions and sacred, calligraphic detailing give even a few letters the weight of an inscription.
