Larry Gonick and Robert Crumb got me interested in the Franks(and Crecy is, really, first-person Larry Gonickness) and I am amazed these were more or less the founders of medieval Europe. In fact, I'm amazed that they didn't kill each other long before battling everyone else.
I wish I had that Crumb strip about the queen who was jealous of her daughter's beauty and tried to kill her by smashing the lid of a trunk full of jewels down on her neck. Now a story of the Franks--THAT would be an interesting comic.
