  • A plague doctor was a special medical physician who treated those who had the plague. They were specifically hired by towns that had many plague victims in times of epidemics. In the seventeenth and eighteenth centuries, some doctors wore a beak-like mask which was filled with aromatic items. The masks were designed to protect them from putrid air, which (according to the miasmatic theory of disease) was seen as the cause of infection.[3]
