In 1293 he arrived at Genoa from this disastrous mission, and he appears to have proceeded immediately to Naples, where he remained till the pontificate of Celestin V., teaching publicly his _Ars Magna_ and _Arbor Scientiarum_. In December 1294, he repaired to Rome to persuade the Pope to send missionaries to the infidels, and he appears to have obtained the establishment of several colleges for the study of oriental languages. Moreover, the University of Paris, by an authentic act, adopted and recommended the use of his short method of acquiring knowledge, and some of his more important philosophical doctrines. Still, his missionary efforts were not generally successful, and he again wandered from place to place, confuting heretics. He travelled to Montpellier, where he was received with distinction by Raymond Gauffredy, General of the Order of St Francis. He obtained letters of association, as a benefactor to the order, the superiors of which were put under his direction, and he taught his method in their houses. He preached in Cyprus against the Nestorians and Georgians, striving to bring them back to the bosom of the Church. He addressed himself for assistance in his manifold enterprises to the Kings of France, Sicily, Majorca, and Cyprus, but generally in vain. In 1308 he returned to Paris, where he conversed with the celebrated Johannes Scotus, who is known as the subtle doctor. He had the satisfaction to find that King Philip le Bel had directed the oriental languages to be taught in the University of Paris. This induced Raymond to proceed in the following year to Ferdinand IV., King of Castile, to engage him to unite with the King of France for the recovery of the Holy Land, but this oft-repeated and invariably disastrous and futile enterprise was fortunately not undertaken. He ventured again to Africa, landed at Bona, that ancient Hippo which was the diocese of St Augustine, and despite the opposition of its Mohammedan inhabitants he succeeded in converting seventy followers of the philosopher Averroës. Thence he travelled to Algiers and converted many, which brought down on him the persecution of the authorities. A bridle was put into his mouth, as if he were a horse, and he was deprived by this means of the free use of speech for the space of forty days; he was then publicly beaten, and expelled from the kingdom. He had no other road open to him but to return to Tunis, where sentence of death awaited him, but he remained concealed, and shortly after proceeded to Bugia. There he confounded the doctrines of the Mohammedan priests, successfully avoiding innumerable deadly snares prepared by the people against him at the suggestion of their religious teachers. He was at length cast into a miserable dungeon, where he might well have perished, but the solicitations of certain Genoese merchants obtained him a better prison, in which he was confined for six months. Here the Mohammedan
