Petronela Rzewuska was a wife of Adam Rzewuski, a castellan of Podlasie. As Petronela’s iconography is unknown, the attribution is based on the biographical data of Adam Rzewuski. It is established that Adam (?–1717, Krzywda coat of arms), the son of Michal Florian Rzewuski, was Cavalry Master of the Crown and a castellan. His wife was Petronela Zbroszkowna. (Assumptions about the person portrayed were made by T. Sabodash). The half-length portrait in a delineated oval depicts a figure of a woman in a fashionable low-necked dress and a dark blue cape, with her hair gathered up forming a neat braid. The painter carefully painted the features of the woman, in particular dark black eyebrows and almond-shaped eyes with a piercing gaze. The painting by a naive artist is characterized by bright colors, excessive detailing of the image and accessories, planar manner of execution, and solemnity.
