Our unpublished painting depicts the same subject as another oil painting by Giani, published in 1979, originally in the collection of Pico Cellini (1903-2000).
The published work, also unsigned, is smaller in size and painted in a sketchy manner. It lacks details that
appear in our painting, such as the playing cards and the bag of coins in the foreground on the right.Ottani Cavina connected the published work to a famous drawing by Giani preserved at the Uffizi, which shares its themes, and which she dates within the 18th century, Il Negromante.
We believe our version predates the published painting. In fact, it has a more pictorial, less sketchily character, which brings it closer to works such as Giani's Samson betrayed by Dalida  (1783) at the Accademia di Belle Arti in Parma.
