In the Sacred and Profane Love 1513-1514, by Italian Renaissance painter Tiziano Vecellio (Titian) we see two women that could be sisters, however they are the same person in two aspects. At first thought the clothed figure on the left may appear to be the representation of the sacred and the nude being profane, but actually it is the reverse. We notice in the background of the clothed figure a castle representing earthly attachment and in the nude we see a church representing spirituality. The sacred figure holds a lamp with the eternal flame, and the profane holds a bowl and flora. Cupid is between them stirring the waters within a fountain or tomb on which both are seated, joining them. We also notice they are both wearing red and white. The celestial goddess (Venus) is seated higher and looks directly at her earthly counterpart, imparting her blessing. Venus has her legs together thereby closing off her genitals, on the other hand her other side although clothed has her legs parted implying her availability for sensual love. The earthly figure looks out of the painting directly at the viewer thereby creating a triangulation, in which she is saying I am the earthly embodiment of the sacred and sensual meaning of love. The whole image is showing this duality within one woman.
The painting was officially commissioned by Niccolo Aurelio, however it maybe that it was his future wife Laura Bagarotta who may have actually done so instead. In her excellent thesis: Female Duality and Petrarchan ideals in Titian’s Sacred and Profane Love, Julianne C. Kaercher makes the case for this and also expands in much more detail on the background of the painting and the inspiration for it. See link:
