For 10 points, name this painting of a recument goddess of love staring at her reflection, a work of Diego Velázquez.
Kenneth Clark argued that this painting was ultimately derived from a cast of the Borghese Hermaphroditus, and analysis established that a sheet in this painting was originally a deep mauve that has faded.

A single brushstroke of black-laden paint was used to trace the line from the middle of the primary figure's back to her thigh, and a winged child drapes ribbons of pink and grey over the ebony frame of a mirror, which reflects the face of the primary figure, who is a brunette sitting on a sheet of grey-black satin.
