Still life with a ledger, a skull and other objects. Oil painting, 1766.

The painting shows objects which are in different ways reminders of death and transience. It can be called a "Vanitas" painting. Left, a huge ledger, inscribed "Debiti Tomo X" (Debts, volume 10), lying on its front cover. On top of it are ferns and an owl. It rests on an open medical manuscript, in which chapters on cancer and plague are visible. A magnifying glass rests on the manuscript. Right, a human skull, a rat, and a glass vase containing flowers. Far left, an oil lamp on a ledge. A tab inscribed "1766" protrudes from the pages of the medical manuscript
