How to Get a Manicure, c. 1150
Tacuinum sanitatis (14th c., Biblioteca Casanatense)
One who has very ugly nails should smear them with liquid from the little bladder of the bumblebee and tie it with a band. He should do this until they become beautiful.
Hildegard of Bingen, Physica (trans. Priscilla Throop)
Better make sure your beautician is also trained in entomology.
I didn't know Hildegard of Bingen gave beauty advice on top of the science, music and playwriting - and terrifying the men in the Church. Amazingly versatile lady!
How does one find the "little bladder" of the Bumble Bee?
Surely that would involve killing the beautiful little creature?
