ENThe object of the present research is several portraits, which formerly belonged to the collections of the Vilnius Museum of Antiquities and today are held at the National Museum of Lithuania in Vilnius and the State Historical Museum in Moscow. In the course of writing a dissertation on the history and reconstruction of the iconographic collection of the Vilnius Museum of Antiquities, the author succeeded in specifying the attribution of some works. These works attracted attention by the level of their execution or exceptional iconography, and intrigued by the represented characters, their origin, or merely by mistakenly identified represented persons. At first, the portraits held at the National Museum of Lithuania should be mentioned. It is a portrait of Michał Walicki (1745-1826), which was previously identified as an image of Joachim Ignacy Litawor Chreptow- icz (1729-1812). There is no doubt that it is a copy of the lost original by Johann Baptist Edler von Lampi (1751-1830). There is also a portrait of the mounted King Stanisław August Poniatowski (1732-1798), which is similar to the works of the Krakow-based artist Michał Stachowicz (1768-1825) in the manner of execution. A portrait of Maciej Radziwiłł (1749-1800), whose author presumably is Józef Peszka (1767-1831), also deserves to be mentioned.The previously unattributed portraits of the Field Hetman of Lithuania, Ludwik Tyszkiewicz (1748-1808), and the Jesuit Józef Katenbring, alias Katembring (Katem- brynk, Katenbringk etc., 1730-circa 1805), are also held in the National Museum of Lithuania. The latter portrait has been previously described as a portrait of an unknown clergyman. Among the portraits held at the State Historical Museum in Moscow, the images of Michał Kleofas Ogiński (1765-1833) and Adam Mickiewicz (1798-1855) are described. Not only the iconography of these works, but also their possible authorship is analysed. The attribution of the portrait of the artist Jan Darnel, alias Damehl (1780-1840) has been performed. In the case of the portrait of the Professor of Vilnius University, Jean Claude Pinabel de Verriėre, alias Jan Pinabel (1766-after 1827), the represented person was recognised and the authorship of Jan Rustem (1762-1835) as well as other data were established.
