Paris grew but slowly under the Frankish kings. They lived ill at ease within city walls. Children of the fields and the forest, whose delight was in the chase or in war, they were glad to escape from Paris to their villas at Chelles or Compiègne.

But the civil power of the Church grew apace. In the early sixth century one-third of the land of France was held and administered by the monasteries. The abbots of St. Germain des Prés held possession of nearly 90,000 acres of land, mostly arable, in various provinces of France. Their annual revenue amounted to about £24,000 of our money: they ruled over more than 10,000 serfs. From a list of the lands held in the ninth century by the abbey of St. Pierre des Fossés,[30] founded by Clovis II. about eight miles from Paris, and published in the Trésor des pièces rares ou inédites, we are able to form some idea of the vast extent of monastic possessions in the city. The names of the various properties whose boundaries touch those of the abbey lands are given. Private owners are mentioned only four times, whereas to ecclesiastical and monastic domains there are no less than ninety references.

These monastic settlements were veritable garden cities, where most of our modern fruits, flowers and vegetables were cultivated; where flocks and herds were bred and all kinds of poultry, including pheasants and peacocks, reared. Guilds of craftsmen worked and flourished; markets were held generally on saints’ days, and pilgrimages were fostered. Charlemagne was an honest coiner and a protector of foreign traders; he was tolerant of the Jews, the only capitalists of the time, and under him Paris became the “market of the peoples,” and Venetian and Syrian merchants sought her shores.

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. 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; some 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.

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.

In 841 the black boats of the sea-rovers for the first time entered the Seine, and burnt Rouen and Fontenelle. In 845 a fleet of one hundred and twenty vessels swept up its higher waters and on Easter Eve captured, plundered and burnt Paris, sacked its monasteries and churches and butchered their monks and priests. The futile Emperor Charles the Bald bought them off at St. Denis with seven thousand livres of silver, and they went back to their Scandinavian homes gorged with plunder—only to return year by year, increased in numbers and ferocity. Words cannot picture the terror of the citizens and monks when the dread squadrons, with the monstrous dragons carved on their prows, their great sails and three-fold serried ranks of men-of-prey, were sighted. Everyone left his home and sought refuge in flight. The monks hurried off with the bodies of the saints, the relics and treasures of the sanctuary, to hide them in far-away cities. In 852 Charles the Bald’s soldiers refused to fight, and for two hundred and eighty-seven days the pirates ravaged the valley of the Seine at their will. Never within memory or tradition were such things known. Rouen, Bayeux, Beauvais, Paris, Meaux, Melun, Chartres, Evreux, were devastated. The islands of the Seine were whitened by the bones of the victims. Similar horrors were wrought along the other rivers of France. Whole districts reverted to paganism. In 858 a body of the freebooters settled on the island of Oissel, below Rouen, and issued forth en excursion to spoil and slay and burn at their pleasure. They made of the once rich city of Paris a cinder heap; the cathedrals of St. Germain des Prés and of St. Denis alone escaped at the cost of immense bribes. Charles ordered two fortresses to be built for the defence of the approaches to the bridges, and continued his feeble policy of paying blackmail.
