One of the Museum’s most interesting artefacts is the Tarło family tree, acquired in 2006, painted on canvas. It is dated to the first half of the 18th century. This large-scale painting (3.2 x 2 metres), once a scroll on rollers, is a very valuable aide-material for learning about the history of the Tarło family and Polish Sarmatism culture. This is the only example of a magnate family tree painted on canvas surviving in Poland, an expression of the ‘family pride’ inherent in Sarmatian culture. In the central part of the painting a tree whose trunk grows out of a rectangular base, a sort-of world map with several countries marked on it with ‘Polonia’, as the Tarłos’ homeland, in the centre. On the sides of the trunk are figures sitting on plinths: on the left, a woman with a laurel wreath on her head symbolising Poland, and on the right, a knight who is undoubtedly an allegory of the family’s progenitor. Along the longer sides and bottom edge of the canvas are numerous cartouches with the coats of arms of families and towns related to the Tarłos. Above the top of the tree is an oval medallion with a depiction of Jan Tarło, Voivode of Lublin, most likely the sponsor of the canvas.
