The Romans always cremated the remains. I never heard of a Roman mummy - or daddy. Passing strange...worship of dead corpses was never a Western idea, Greek or Roman.
Many Romans converted to the Worship of Isis and Osirus with its promiss of eternal life. When they did they discarded creamation and took up mummification. Cleopatra, who was never a pharoah, took the title of Living Isis. She had many followers of her cult in Rome itself. I am told there are more things still buried in Egypt than there are dug up even now. One Pharaoh’s Tomb, Ramases VIII, is still lost in the Valley of the Kings!
