During big fights in the arena or gladitorial ring between two well known or important warriors. When one looses and dies, the crowd throws copper coins into the arena for the slain warrior to take with them on their passage of death. This is to make their passage and afterlife richer and less troubled. It is a sign of respect.
The Mad Pope is a wandering mercenary. He is very well deranged as he considers himself to be the pontiff of the dominant faith. His robes are tattered, his mitre has seen better days and there are surely lice in his long ratty beard. What sets him apart from most addle-pated would be holy men is that he has armor under his robes and carries a large crossbow and several one-handed swords. While many would discout him as just another lunatic, for some reason, he inspires others around him and has demonstrated the ability to lay on hands and heal the wounded.
