Some people estimate 70 million mummies, but I think that's an underestimate. Mummification was carried out in Egypt, as I mentioned, for over 3,000 years. I'm sure more human mummies were made during this time period. If you look at animal mummies, several hundred thousand mummies have been found even in one cemetery. Countless mummies have been destroyed by tomb raiders seeking treasures within their linen wrappings.
The practice of mummifying the dead began in ancient Egypt c. 3500 BCE. The English word mummy comes from the Latin mumia which is derived from the Persian mum meaning 'wax' and refers to an embalmed corpse which was wax-like.
