Dr. Beak

Plague doctors wore a mask with a bird-like beak to protect them from being infected by the disease, which they believed was airborne. In fact, they thought disease was spread by miasma, a noxious form of  “bad air “. To keep away bad smells, the beak could hold dried flowers including roses and carnations, herbs, spices, camphor, or a vinegar sponge
