@medieval_illuminations Supplementjng with a more descriptive #AltText: The illustration shows a partly submerged root with a face and abundant green leaves atop. A dog eating from a bowl, is leashed to the root. A man walks away, covering his ears.

From Wikipedia: According to the European folklore (including England), when the root is dug up, it screams and kills all who hear it, so a dog must be attached to the root and made to pull it out.
