The painting is a work of undetermined authorship. Its time of creation is probably the same or close to the time of creation of the altar of Saint Anne (1636), to which the painting was probably intended from the beginning. The work seems to be a conservative example, both in formal (wooden support, gilded background) and iconographic terms of current in the Lesser Poland sacral painting. The painting presents an iconographic theme called the Holy Kinship. It gained particular popularity in late Gothic and Renaissance art. Most often, as in the case of the work in question, Mary and the Child and Saint Anne sitting together on a bench in the compositional scheme proper for the representation of Saint Anne who was accompanied by distant relatives. In the case of the work in question, Mary, Saint Anne and Jesus are accompanied only by Saint Joseph, shown on the left of the composition and Saint Joachim depicted on the right.
