Portrait of Mikołaj Tyszkiewicz, Leliwa coat of arms (?–1796 or 1798), canon in Vilnius

Executed in oil on canvas, the work employs a restrained palette of deep blues, muted browns, and metallic highlights. The brushwork renders the fabric’s texture and the reflective surface of the mirror with subtle chiaroscuro, creating a modest three‑dimensional presence against the plain background.

The portrait is dated to the final years of Tyszkiewicz’s life, around 1796–1798. It likely originated in a private family collection of the Tyszkiewicz lineage before entering a public institution, though specific acquisition records are not documented.

In the late eighteenth century, portraiture of clergy and aristocracy in the Polish‑Lithuanian Commonwealth often combined personal likeness with symbols of rank. The inclusion of the Leliwa coat of arms aligns with contemporary practices of affirming noble identity within ecclesiastical portraiture.

The painting serves as a visual record of the Tyszkiewicz family’s status and the aesthetic conventions of its era, offering scholars insight into the intersection of noble heraldry and ecclesiastical representation in late‑enlightenment Lithuania.
