This ivory mirror case cover features the allegorical iconography of the god of love.
He is sat at the top of a gnarled tree, the trunk of which and two main branches divide the area into four "chambers" of greenery. In each of them there is a couple of lovers, whom the god aims his arrows at.
This mirror case cover comes from the collection of Victor Martin Le Roy, which was passed down to his son-in-law Jean-Joseph Marquet de Vasselot, who was director of Department of Decorative Arts at the Louvre and the Musée de Cluny from 1926 to 1933.
