ProverbWisdomEnglish origin1579

You can't make a silk purse of a sow's ear

Meaning: Inferior materials cannot be transformed into superior products through effort alone.

Origin: The earliest record is in Stephen Gosson's Ephemerides of Phialo (1579), and later writers called it an old saying. In 1921 the chemist Arthur D. Little set out to disprove it: he had glue made from sows' ears spun into fibers and woven into silk purses. One is now at the Smithsonian, the other at MIT.
