This is a Plague Doctor with a leather bird mask and incense. In the old days doctors didn’t understand germs and they thought the plague came from birds and bad air – so they wore a spooky bird mask and jammed it full of incense to battle it. It gave them a sinister look. I can imagine the panic Europe felt when one in 3 people got sick and died from the plague. It must have felt like the end of the world.
