↑Pepin's name can be very confusing. Historically, historians have vacillated between preference for Pepin, derived from the French Pépin, and the German Pippin. His nickname is also subject to whims, le Bref being translated as either "the Short" or "the Younger". The Younger is explained as referring to the fact that he was the younger of the two Arnulfing Pepins who ruled as mayors of the palace; the Short as deriving from the tales of Notker Balbalus regarding the King's diminutive size. More novel suggestions include a suggestion that "the Short" referred to his hair—since he was the first Frankish king to wear his hair shorn short. Dutton, PE, Charlemagne's Mustache.
