The figure of Saint Jerome is one of the altar sculptures of the Church of the Assumption of the Virgin Mary in the village of Bishche. The peculiarity of the figures of the main altar is that instead of the usual images of prophets, apostles or evangelists, the author reproduced the sponsors of the Sieniawski family: Hieronim, Elzbieta, Mikolaj, and Katarzyna. The full-length sculpture of a man is executed professionally. The Mannerist style features in the capricious perspective and excessively elongated proportions of the figure are characteristic of Pfister's style. The frontality of the figure is enhanced by the folds of garments, which fall vertically. Saint Jerome's face impresses with the thoroughness of reproduction – a high open forehead, well-defined eyebrows, and a magnificent beard that falls on his chest in soft waves. The sculpture conveys the portrait features of Adam Hieronim Sieniawski, with whose assistance, as documented, Pfister stayed in Berezhany since 1612. The man is depicted in the image of Mark the Evangelist, as evidenced by the sculptural image of the head of a lion – a symbol of the Evangelist. The author skillfully conveyed the mood of the composition with the help of soft lines.
