From Nights, 8:30 pm on 4 November 2025

Boiled, burned, mixed with honey, or simply placed on the stomach of someone with tuberculosis: in Europe, over one thousand years ago, frogs were believed to contain miraculous medicinal properties. 

Greti Dinkova-Bruun is a Fellow and Library Director at the Pontifical Institute of Mediaeval Studies in Toronto, and has been looking into medieval texts to find how frogs were depicted and used for medicinal purposes.

She speaks to Emile Donovan about the spell frogs had over people during the Dark Ages.
