In general, the "inspiration" happened, as it is.
We went through a black death story. And we were shown treating, if they can be called “doctors”. Which is not something that was not treated, but pushed through the infected. This creepy bird's beak was for not breathing spoiled air and not feeling the smell of decaying corpses.
  But the most terrible, as it seemed to me in the lesson, is a cane. My drawing is cropped, so it is not. To her, these doctors pushed away patients who were rushing under the feet of the doctor and asking for healing. They were doomed to death.
In fact, you can talk for a long time on this topic. That the doctors did not even try to cure the sick, but only defended themselves. What was possible for them and there was no way out to act differently, because medicine was not very well developed. That they did not even understand that it is necessary to wash, not once in a lifetime, but daily. Everyone will find their answer on this topic of reasoning.
