In Gallo-Roman days few were the churches outside the cities, but in the great emperor's time every villa[31] is said to have had its chapel or oratory served by a priest. Charlemagne was a zealous patron of such learning as the epoch afforded, and sought out scholars in every land. English, Irish, Scotch, Italian, Goth, and Bavarian--all were welcomed. The English scholar Alcuin, master of the Cloister School at York, became his chief adviser and tutor. He would have every child in his empire to know at least his paternoster, and every abbot on election was required to endow the monastery with some books. The choice of authors was not a wide one: the Old and New Testaments; the writings of the Fathers, especially St. Augustine, the emperor's favourite author; Josephus; the works of Bede; some Latin authors, chiefly Virgil; scraps of Plato translated into Latin--a somewhat exiguous and austere library, but one which reared a noble and valiant line of scholars and statesmen to rule the minds and bridle the savage lusts of the coming generations of men. Under Irish and Anglo-Saxon influences the cramped, minute script of the Merovingian scribes grew in beauty and lucidity; gold and silver and colour illuminated the pages of their books. The golden age of the Roman peace seemed dawning again in a new _Imperium Christianorum_. [Footnote 31: The villa of those days was a vast domain, part dwelling, part farm, part game preserve.] Towards the end of his reign the old emperor was dining with his court in a seaport town in the south of France, when news came that some strange, black, piratical craft had dared to attack the harbour. They were soon scattered, but the emperor was seen to rise from the table, and go to a window, where he stood gazing fixedly at the retreating pirates. Tears trickled down his cheeks and none dared to approach him. At length he turned and said: "Know ye my faithful servants, wherefore I weep thus bitterly? I fear not these wretched pirates, but I am afflicted that they should dare to approach these shores, and sorely do grieve when I foresee what evil they will work on my sons and on my people." His courtiers deemed they were Breton or Saracen pirates, but the emperor knew better. They were the terrible Northmen, soon to prove a bloodier scourge to Gaul than Hun or Goth or Saracen; and to meet them Charlemagne left an empire distracted by civil war, and a nerveless, feeble prince, Louis the Pious, Louis the Forgiving, fitter for the hermit's cell than for the throne and sword of an emperor.
