The history of the Ibaloi mummies is still largely oral. It is even uncertain when the last mummy was created; according to staff at the town’s museum, mummification was attempted most recently in 1907 but the wrong combination of herbs was used. It’s possible that the last successful mummification was in 1901, of the great-grandmother of former village mayor Florentino Merino.
What is known is the general procedure, which could take up to a year to complete. The body would have been bathed and dressed, then tied upright to a chair with a low fire burning underneath to start the drying process. Unlike in other mummification rituals around the world, the internal organs were not removed. A jar was placed under the corpse to catch the body fluids, which are considered sacred, while elders began the process of peeling off the skin and rubbing juices from native leaves into the muscles to aid preservation. Tobacco smoke was blown through the mouth to dry the internal tissues and drive out worms.
