The date is December 1421. Henry's first son has just been born in England. Henry is in France and everything is getting on top of him. He needs some help. Some psychological help.
The Facts
OK, so he probably didn't have OCD, but he certainly seems to have elements of it that stand out in his behaviour. He comes across as a perfectionist and micro-manager. He had very little control over his life as a child and had an inconsistent relationship with his Father and didn't get on with his Brother either.
He really did get hit by an arrow and the surgeon did invent a special device to remove it as well as use alcohol and honey to clean it. It is why he was only painted showing his best side (see picture four below). He also shaved every day at a time when most men had beards and an unusual bowl, monk-like haircut.
He was legendary in his discipline of his troops in terms of looting and behaviour. The story about the trumpeter that annoyed him is true. He had a strong attention to detail and insisted on overseeing most things himself, even when abroad in France. I think it's kind to say that he had control issues.
