in terraces, like the seats of an amphitheatre, were the suburbs, verdant with the luxuriant vegetation of every country that could be reached by the enterprise of man, through whose leafy screen appeared at intervals the gayly painted villas of the merchant princes or the sumptuous and imposing palaces of the Norman aristocracy. Amidst the numerous measures originated and brought to maturity by the new domination, it is remarkable that no especial encouragement was afforded to institutions of learning. A tradition exists of the academy of the great Count Roger, but it is only a tradition. No national university was founded to perpetuate the fame or to exalt the benefits of regal patronage. No general plan of promoting the education of the masses was inaugurated. The Jewish and Saracen schools, however, still survived; they were often the recipients of royal generosity, and were resorted to by such Christians as were desirous of profiting by the valuable instruction they afforded. As elsewhere in Christendom, the clergy were the general depositaries of knowledge,--an advantage which they thoroughly understood, and were by no means willing to voluntarily relinquish. In one respect alone their power was seriously curtailed. The spurious medicine of the time, as practised under the sanction of the Holy See, had raised up a herd of ignorant and mercenary ecclesiastical charlatans. These operated by means of chants, relics, and incense; and their enormous gains were one of the chief sources of revenue to the parish and the monastery, and a corresponding burden on the people. King Roger abolished this abuse, and required an examination, by experienced physicians, of all candidates for the profession of medicine and surgery, restricting those whose superstition was ineradicable or whose learning was deficient to the clandestine ministrations of the shrine and the confessional.
