It seems like you might be combining two separate figures:
* Osiris: An Egyptian god, often depicted as the king of the underworld. He is known for his association with death, resurrection, and the afterlife.
* Imhotep: A high-ranking Egyptian official who served as a vizier, architect, and priest during the Third Dynasty of Egypt (c. 2686–2613 BC). He is best known for designing the Step Pyramid of Djoser at Saqqara, one of the earliest and most important pyramids in Egypt.
It's possible you've encountered this combination in a fictional context, perhaps a book, movie, or game. If you can provide more information about where you saw "Osiris Imhotep," I might be able to offer more specific details.
