In this easy intercourse between sovereign and subject lay the secret of Charlemagne’s personal magnetism. To warriors and churchmen as to officials and the ordinary freemen of his demesnes he was not some far-removed authority, who could be approached only through a maze of court intrigue, but a man like themselves with virtues and failings they could understand. If his temper was hasty and terrible when roused, it would soon melt away into a genial humour that appreciated to the full the rough practical jokes in which the age delighted. The chronicles tell us with much satisfaction how Charlemagne once persuaded a Jew to offer a ‘vainglorious bishop ever fond of vanities’ a painted mouse that he pretended he had brought back straight from Judea. The bishop at first declined to give more than £3 for such a treasure; but, deceived by the Jew’s prompt refusal to part with it for so paltry a sum, consented at length to hand over a bushel of silver in exchange. The Emperor, hearing this, gathered the rest of the bishops at his court together--‘See what one of you has paid for a mouse!’ he exclaimed gleefully; and we may be sure that the story did not stop at the royal presence but spread throughout the country, where haughty ecclesiastics were looked on with little favour. We are told also that Charlemagne loved to bombard the people he met, from the Pope downwards, with difficult questions; but it was not merely a malicious desire to bring them to confusion that prompted his inquiries. Alert himself, and keenly interested in whatever business he had in hand, he despised slipshod or inefficient knowledge. He expected a bishop to be an authority on theology, an official to be an expert on methods of government, a scholar to be well grounded in the ordinary sciences of his day. Hard work was the surest road to his favour, and he spared neither himself nor those who entered his service. Even at night he would place writing materials beneath his pillow that if he woke or thought of anything it might be noted down. On one occasion he visited the palace school that he had founded, and discovered that while the boys of humble birth were making the most of their opportunities, the sons of the nobles, despising book-learning, had frittered away their time. Commending those who had done well, the Emperor turned to the others with an angry frown. ‘Relying on your birth and wealth,’ he exclaimed, ‘and caring nothing for our commands and your own improvement, you have neglected the study of letters and have indulged yourselves in pleasures and idleness.... By the King of Heaven I care little for your noble birth.... Know this, unless straightway you make up for your former negligence by earnest study, you need never expect any favour from the hand of Charles.’ [Sidenote: Government of Charlemagne]
