Prolific and versatile, he painted allegories, landscapes, and large-scale works for churches and convents. Today he is remembered mostly for his still lifes, a genre he popularized in 1620s Madrid.

A sumptuously dressed and armed dwarf holds a ruler´s staff, an attribute of power that cannot have corresponded to his status. He was probably one of the court buffoons, who were showered with presents and dressed in ostentatious luxury. Since the sixteenth century, portraits of these figures were quite customary, although it was Velázquez who explored this genre with singular mastery. The date generally attributed to this extraordinary portrait indicates that the model might be Bartolillo, a dwarf whose presence in the Palace is documented between 1621 and 1626.
