Plague doctors were employed in various methods whenever plague set in. The earliest documentation of these individuals being hired go as far back as the mid 500s AD. The plague doctor image that we as a general public are familiar with was not seen until the 1600s. It was then that the “traditional” plague doctor costume was created. The costume consisted of a cloak made of heavy fabric covered in wax to protect the doctor’s body, and a mask to keep out the sick air.
