Italian scientists analyzed, took CT scans of nineteenth-century mummies at the mummy museum, and found many secrets regarding the mummification of this period.

These mummies were preserved by anatomist Giovan Battista Rini (1795-1856) preserved by "petrification" by bathing mummies in a mixture of mercury and other heavy metals.

The mummies and mummies from the 1800s in different states are preparing CT scans at a hospital near Salò, Italy.
