The 14¾ x 21½ in (37.5 x 54.5 cm) framed capricci are painted in gouache on paper and are two of just six works by the artist in this medium. Datable to the 1740s, like the other four gouaches recorded, one depicts a chapel set on a hill while the other is a capriccio of classical ruins viewed through an arch.
They are estimated at €350,000-400,000.
Both paintings are part of a viewing of selected highlights from the sale series to be held by auction house Cambi which are on display at the second floor gallery at 23 Bruton Street from November 5-9.
The auctions will be staged in Genoa from November 15-17 and include Old Masters, silver, Italian maiolica and other ceramics, furniture and works of art and a selection of furnishings and paintings from the Palazzo Corner Spinelli in Venice.
Highlights from their December sale of Asian works of art will also be on view.
