It is said that the great Renaissance artist Michelangelo (1475-1564) studied cadavers by candlelight in a dark morgue (while enduring the smell of rotting flesh) in order to better understand the structures of bone and sinew and muscle.

The fruits of his efforts are evident in his painting "The Creation of Adam" on the ceiling of the Sistine Chapel in Rome and in his marble sculpture "David" in the Galleria dell' Accademia in Florence.

Courts of law sometimes use the term "cadaver" to refer to a dead body, as do recovery teams searching for bodies after a natural disaster; such as, an earthquake or a flood.
