The arrow in the back turned out to be a Roman nail.
Philippa Langley insisted on draping the box containing Richard's bones with his colours. The osteologist demurred. What if it turned out not to be him? In the event amateur passion got the better of professional caution; Langley took the risk- of jumping the gun and looking stupid- and once again proved to be right.
While Richard was being carried from the battlefield- naked, slung over the back of a horse like a Western bad-man- some oik stabbed him in the bum. It only happened the once. One would like to think the oik got smacked down for it.
The facial reconstruction gives us (to quote Simon Farnaby) "a bonny lad". The nervy, prematurely aged person in the portraits is replaced by a handsome, smooth-faced, cocky young man. The real Richard seems to have looked remarkably like Olivier's version of him.
