This is one of a kind example of miniaturised engraving on ivory. The top side of the item is a superbly rendered sundial. It can be inferred that the item belongs to that typology of objects bearing erotic scenes, that have been designed to have a reverse. The erotic scene is therefore concealed by a reverse side, magnificently and finely executed employing an intaglio technique. This side of the object is inserted into an elegant and minimalistic frame of Neo-classical memory, that creates an interesting contrast with the formal opulence it surrounds. On the opposite side, we can observe an erotic scene of great visual power, representing two lovers in a domestic scenery. The anatomic precision and the mastery in the realization of the drapery lying behind the couple make of this object a remarkable example of miniature.
