Not that a mummy laid an egg, no. Rather these are the sort of eggs that a mummy would have eaten, presumably before becoming a mummy. A dish called “eggah” if you will. From the linked article: “Eggah is the Egyptian version of a baked egg omelet. Archeologists have found that ancient Egyptians have been eating variations of eggah since the Egyptian bronze age in 3150 BCE. They would get eggs from wild fowl that lived along the Nile.” Then the linked article goes on to provide you, any of you who might be interested in making the dish, a recipe.
Anything pertaining to ancient Egypt is guaranteed, as any of you who frequently follow this site will know, to capture my attention. Even something as admittedly lighthearted as this particular piece. I’m also a big enough geek to try this dish (not that I’d try preparing it myself; no good could come from that!) for no other reason than that the ancient pharaohs were known to eat it.
After death and mummification, did mummies retain their appetites for eggah? They *did* bury mummies with foodstuffs, so the ancient Egyptians must have believed mummies still capable of eating after embalming and entombment. I don’t know about you all, but the idea of a revenant mummy snacking on an omelet is just hilarious to me.
