This it OT from you post, but when I read "mummy extracts", my brain read extracts as in 'plant extracts'.
Well, it made me laugh. Thanks for the link.
Play revived using mummy extracts
An Egyptian mummy contained the ancient text
A Greek play believed lost when the Library of Alexandria is said to have burnt down in 48 BC is to be revived after fragments of text were found in an Egyptian mummy.
Papyrus inscribed with excerpts of Aeschylus's Trojan War trilogy Achilles were found by archaeologists.
