Fructuosus cultivated literature sedulously, and led his monks to do likewise. He also wrote poetry, some of which is still extant; it is quoted by Florez. His monks kept great flocks of sheep, the profit of which they spent in charity. Some years before his death he was made archbishop of Braga, but he did not cease to practise the rule of monastic life, and he built many new monasteries. He surveyed all the coasts of Spain from Cape Finisterre to Cape St. Vincent, crossed the rivers Duero and Guadalquivir, reaching the promontories and islands, even to the spot where Cadiz now stands, and seeking everywhere asylums for prayer and solitude. “Thanks to him,” continues Montalembert, in a prophetic strain, “the extreme frontiers of the West become guarded by a line of monastic garrisons. The great waves of the ocean rushing from the shores of another hemisphere, from that half of the world still unknown to Christians, is met by the gaze and the prayers of the monks from the lofty cliffs of the Iberian Peninsula. There they stand firm, awaiting the Mohammedan invasion; there they endure and survive it; there they preserve a nucleus of faith and Christian virtue, for those incomparable days, when, from those shores freed by unwearied heroism, Spain and Portugal shall spring forth to discover a new world and to plant the Cross in Africa, in Asia, and in America.” St. Fructuosus is still one of the favourite saints of Galicia. The cathedral of Santiago has a chapel dedicated to him, built in 1696,[61] and his day is honoured by every peasant in the land. Galicia has some valuable archæological monuments of the eighth century, to which we shall refer in a later chapter, but she produced no great literary character whose history need detain us here. It was in this century that the Moors first invaded the Peninsula; and Galicia, though not then invaded, began from this time to send the flower of her youth to fight the Saracens. In the ninth century there took place the discovery of the tomb of the apostle St. James on the spot where the cathedral of Santiago now stands, a discovery which led to the concentration of the reverential love of all medieval Christendom upon that distant corner of Spain, and eventually caused Santiago to rival Jerusalem as a centre for holy pilgrimage from all parts of the known world.
