A head looking to the left with wild greenish-yellow hair with two trailing flesh-coloured worms attached to it. The head is shown between lines of lettering on a manuscript page. Image from Biblioteca Apostolica Vaticana, Pal. lat. 291 (De rerum naturis), folio 96r.

Our final image is from a 1425 version of the encyclopaedia created by Rabanus Maurus (c780-856). It is an emigraneus, a worm that infests the human head and causes migraines. #medievalmanuscripts #medievalbeasts #rabanusmaurus #emigraneus
