Use Of Vervain, In A Collection Of Medical And Herbal Texts
This manuscript lists herbs and other plants, animals, and birds, and their medicinal uses. Each is illustrated, but the representations were apparently copied from other manuscripts, rather than from life (it would usually be very difficult to identify the subjects of the miniatures without the aid of the text). This manuscript is related to several others, which seem to have been made in the north of England, perhaps Durham.
The top miniature shows a man holding the herb Vervain (Verminatia) while killing a adder with his sword. The lower one shows a doctor attending a sick man who has been bitten by the rabid dog in the lower corner; above them is a hen: if its appetite is good, it is an omen of recovery.
