Bald and Fat

By one of history's quirky little coincidences, both Charles the Bald and Charles the Fat were born on this day, respectively in 823 and 839. Charles the Fat had the distinction of being the last ruler of a united Carolingian Empire. He was widely regarded as a spineless and inept fellow, a waste of (a considerable amount of) skin - though historians are, of course, divided over this verdict. Charles the Fat was inept even in the matter of fathering an heir, though he did manage one illegitimate son.
Charles the Bald, on the other hand, was more successful, alike in ruling an empire and in fathering offspring - among their number Louis the Stammerer and Lothar the Lame. Historians are again divided over the question of whether he was bald; he might even have been exceptionally hairy. But there seems to be no disputing that Charles the Fat was on the large side, and no doubt Lothar the Lame and Louis the Stammerer gamely lived up to their names. It might be fun to revive this habit of labelling royals with descriptive cognomens. We could begin with our own Prince Charles - but no, that would be too cruel (and possibly treasonous)...
