The painting was painted by Raczyński in 1851. Saint Francis was displayed in a classic iconographic convention: in a Franciscan habit and with traditional attributes: a skull and a crucifix. As a symbol of "vanitas", the skull stands for death as the beginning of true life. Unfortunately, since there were at least nine painters bearing that name, working in the Republic in the 19th century, the piece cannot be attributed to any specific artist.
