Spanish school of the second half of the seventeenth century."Portrait of a gentleman."Oil on canvas. Relined.With inscription on the back "Duque de Osuna".Overpaints. Frame and rear extensions. It presents dent and visible restorations on the back.Measurements: 51 x 37.5 cm.The portrait of a knight that we are dealing with here moves away from the usual effigies, presenting the protagonist in an oval of trophies in grisaille. The serious temperament and vehement countenance of the sitter are matched by the pomposity of the composition. Due to its physical and formal characteristics, the canvas was painted in the 17th century, seeking to highlight the grandiloquence of the portrait genre through additional elements that accompany the figure of the sitter.
