If you play video game Assassins Creed series then you should know this character Plague Doctor as he is the one that sells potion to Ezio Auditore .
You know I thought this was just a thing made for video games but the truth is back then Plague Doctor really existed.
A plague doctor was a medical physician who treated victims of the plague. They were specifically hired by towns that had many plague victims in times of epidemics. Since the city was paying their salary, they treated everyone: both the wealthy and the poor.
