Ostap Biliavskyi was the last Lviv artist of the guild masters. The painter skillfully showed individual features of the portrayed people’s faces; in his portrait gallery there are no two similar faces. Among the best works by Ostap Biliavskyi there is a portrait of Dominik Nikorowicz, an assessor (juror) of the tribunal, who came from the Armenian family of Nikorowicz. In 1782, he received nobility from the Austrian Emperor. The portrait of a nobleman is characterised by some introversion and estrangement from the public interest. The bust-length image of the man is barely turned to the right. The man’s clothing is depicted in detail. Skillfully showing the features of Dominik Nikorowicz’s face, the artist managed to capture an image of a good and educated person.
