[29]This is Tersatz, a town of Istria.
[30]These Northmen (or Danes, as they are usually called when they appear in English history) proved themselves the most terrible enemies of civilisation during the next century. “The Monk of St Gall” makes Charles prophesy the ruin that would come eventually on his Empire from these northern sea-rovers. The attacks of the Northmen were among the most direct causes of the subsequent disruption of the Empire of Charles.
[31]This is an exaggeration of Eginhard’s. Charles did, indeed, greatly extend the Frankish dominions; but he strengthened them still more decisively by the improvements which he introduced into the internal order and administration.
[32]The Balearic Sea is the western Mediterranean.
[33]“Non aliter quam proprium suum.” Feudalism in any strict sense of the word was not yet established; but Alfonso was, in effect, “commending” himself to a feudal superior.

[pg 166]

[34]The spelling of the original is retained; but the “Aaron” of Eginhard is the great Caliph Harun-al-Raschid, the Abassid Caliph of Bagdad, whose actions play so large a part in fiction as well as in history.
[35]It is strange, in view of the friendly relations of Charles with the Mohammedan ruler of the East, that later legend so persistently represented Charles as a Crusader, driving the Paynim from the Holy City. The height of unreality is reached when, as in Ariosto, we find Charlemagne relieving the city of Paris, which is being besieged by the Mohammedans.
[36]This elephant caused a great sensation in Europe. His arrival, life, and death are carefully noted by the chroniclers.
[37]The exact meaning of the original is far from clear (ne qua hostis exire potuisset). The ingress rather than the egress is what Charles must have wished to prevent, but there seems no doubt about the reading.
