Summum was founded in 1975 by Corky Ra, who died in 2008 and was the first human to be mummified using a process he developed. His mummiform is on display in the group's sanctuary, a bronze-colored pyramid, which is often visited by students of Egyptology, Menu said. Mummification is part of a Summum belief in "transference" and is meant to ease the spirit's passage after death.
