A self-portrait by Judith Leyster depicts her husband and family friend with several types of these general objects. An obscured image of Pero and Cirnon can be seen in a painting whose title refers to one of these objects. A painting depicting one of these objects may have been completed by the artist’s daughter Maria and shows a woman in a conical striped hat. Along with the title correspondence, the main subject in The (*) Love Letter holds an example of these objects. (-5[1])One of these objects is seen lying on a checkered marble floor near a white jug (10[2]-5[1])and a cane-holding man (-5[1])in another painting by that same artist. That painting featuring these items shows a mirror reflecting a yellow-skirted woman seated at an example of these items called a “virginal.” For 10 points, name these objects, one of which is depicted (10[1])in Vermeer’s The Guitar Player.
