I've been reading"Huck Finn" with my sophomores for over ten years and we've been mystified by the scene where Jim's face is painted blue to accompany the"sick Arab" sign. Recently, during a presentation on the Crusades, a slide was shown. An Arab with a blue face was contending with a crusader. Can you or anyone shed some light on whatever connection there may be here?
The only book I have on hand on the Crusades is Runciman's splendid history, but I find nothing helpful there. Any answers to Mr. McDaniel's query?
