This is a Mariological image in which we can admire the half-length figure of the Virgin Mary watching over the sleep of the Child Jesus. His little naked body, lying on a white cloth, rests on a wooden cross that in turn lies on a cushion. Previously, this extraordinary work had been attributed to the Spanish artist Francisco Bayeu, but the technical analyses and stylistic study carried out by the CAEM have made it possible to attribute its authorship to the Italian artist Paolo de Matteis, a talented disciple of the genius Luca Giordano.
