In the 17th century, the burial of a prominent noble was accompanied by a ceremony in which the portrait of the deceased played a defining role. The casket portraits were drawn "ad vivum" (as if alive) on a silver, copper or tin plate. They had a hexagonal shape due to their placement on the end of the coffin. In the seventeenth century, it was strictly hexagonal; in the 18th century, the basis remained the same hexagonal shape, which acquired a complicated baroque profile. The first requirement for such portraits was to be as similar as possible to the face portrayed. The painter was not allowed to idealise; his task was to capture the individual facial features in detail. The portrait shows Marcin Solski on a dark background. The portrayed face and a part of his shirt peeping out from under the dark overcoat make a bright spot. The facial features are detailed: high forehead, small arched eyebrows, small eyes, handlebar moustache, and double chin. The absence of any inscriptions, coats of arms or detailing of clothing deepens the image of the man.
