Recent news of newly uncovered mummies reminded me of this claim that i have previously seen on twitter before and was wondering if it's a misinterpretations of something factual or if it's actually real.
Though not actually served for dinner as an entrée, yes, in an apothecary's of the 16th and 17th c. it would not be unusual to have, amongst the large jars marked NUX VOMICA and GUMMA ASAFOETIDA one marked MUMIA that contained some ground up mummy. It seems to have been used for a number of things, including ( for some reason) as an aphrodisiac. In one of his essays, "Of Cannibals", Michel de Montaigne would compare the Brazilian Indians eating the bodies of their defeated opponents with the European's eating the bodies of long-dead Egyptians: a notable very early appearance of cultural relativism.
Although the use as a medicine declined, there was a real trade in them , in Egypt, into the 19th c.
There was also fun little discussion of the use of mummies for paint pigment here some time back.
