Arnald’s personality and career have long attracted attention, not only because of his prominence as a practicing physician and writer on medicine and alchemy, and because of his close relations with several kings and popes. He also is noted for his connection with ecclesiastical history, his relations with the Spiritual Franciscans and the theologians of Paris, and for his criticisms of existing conditions in the church of his time,—criticisms which he combined with Joachimite ideas of a speedy end of the world and coming of Antichrist. These points long ago caused his inclusion in Matthias Illyricus Flacius’s Catalogue of Witnesses to the Truth who before our time attacked the primacy of the Roman pontiffs and the various superstitions, errors, and impious frauds of Popery,[2674] and more recently in Menéndez Pelayo’s Historia de los heterodoxos españoles. And it is true that Arnald composed a violent diatribe against the regular clergy of his day and also a Sword of Truth against the Thomists.[2675]

Narrative of his life.

Arnald was a Catalan, although Pope Clement V speaks of him as “a clerk of Valencia.” Arnald writes of his youth as a time of hardship and of himself as “a country practitioner” without literary culture. Yet he came to shine at courts and to defy synods of learned doctors of theology. He also mentions his early education in a Dominican convent and his study of medicine at Naples under John Calamida. During his entire life he seems to have been continually moving about, and his works speak of observations and operations in many towns of Spain, Italy, and France. Some of his treatises were written in Valencia, others in Barcelona, others in Naples, or in Gascony, Piedmont, Bologna, Rome, and even Africa. He was often called abroad to render medical services to popes and other potentates and was frequently employed in foreign diplomacy by the kings of Aragon and Sicily. By 1285 he had won a sufficient reputation as a physician to be called from Barcelona to attend Peter III of Aragon in his last illness. Peter gave him a castle in Tarragona. After that Arnald seems to have taught at Montpellier which was then under the jurisdiction of Aragon. Three later bulls of Clement V in 1309 making regulations for the medical faculty at Montpellier mention Arnald of Villanova as one of the persons by whom the pope has been advised in the matter, and speak of him as having “once long ruled” in that university.[2676] Astruc tells us that in the eighteenth century the house where he had lived was still shown in Montpellier, ornamented with sculptured figures which were interpreted as magic symbols.[2677]

In theological difficulties.

In 1292 Arnald composed a treatise on the significance of the holy name, Tetragrammaton, both in Hebrew and Latin, and on the declaration of the mystery of the Trinity. This and later essays of his in the field of religion were not well received by most theologians, who would have preferred that he confine his efforts to medicine. In 1299 Arnald was sent to Paris with a message from James II of Aragon to Philip the Fair. Here he was arrested by the inquisition, but was bailed out the next day, Nogaret being among those who stood security. Presently he was brought to trial before the bishop and the theological faculty of Paris for a work predicting the coming of Antichrist about the middle of the fourteenth century upon the basis of passages in Daniel and the Erythrean sibyl, and his book was ordered to be burned.[2678] Arnald protested to the king of France and later to a crowd of distinguished people at the bishop’s palace and appealed to Pope Boniface VIII. Finally he was allowed to leave France and in November, 1301, is found at Genoa.

Arnald submitted to Boniface VIII a slightly modified version of his work on Antichrist, accompanied by a tone of pious self-abnegation and considerable shrewd flattery of the pope as “Christ on earth” and “God of gods.” The theologians of Paris, however, had sent a portion of the original text to the pope with the result that Boniface kept Arnald in prison for a time and forced him to abjure his work in secret consistory, but finally said that Arnald had erred only in not submitting the work to him in the first place. After Arnald had treated Boniface successfully for the stone, that pontiff’s estimation of him greatly improved, and he received favorably a new work which predicted the history of the Mediterranean world for the next century until the coming of Antichrist, bewailed the worldliness of the clergy, but upheld the papal power, to which, of course, Arnald looked to further the ecclesiastical reforms which he had at heart. Boniface also presented Arnald with a castle at Anagni, but the sun proved too hot there for Arnald’s head. Early in 1302 he left the papal curia, in April he received permission from King James II to dispose of his property in Valencia. His writings on Antichrist and against certain of the clergy continued, and in February, 1304, he was at Marseilles complaining before the bishop of some Dominicans who had attacked his treatises. He then addressed himself to the new pope, Benedict XI, at Perugia, but was not well received, and complained that the pope had judged and punished him before hearing him. But Benedict’s brief pontificate was soon over and Clement V showed himself more gracious.[2679]

Events of 1305.

Meanwhile in April, 1305, Arnald returned to Barcelona where he found James II sick abed and very glad to see him and to entrust himself to his medical care rather than that of Ermengard Blasius (or Blasii)[2680] who had hitherto attended James. About this time Arnald seems to have interpreted a dream for James, but that monarch later repudiated Arnald’s account of the affair and they were estranged for a time.[2681] Arnald’s will, drawn up on July 20, 1305, by a public notary of Barcelona, informs us concerning his library, other property, generosity to the poor, and reveals the fact that he had a wife and children.

The close of his life.

Arnald, however, still had several years of life before him. A declaration has been preserved which he made in 1306 concerning the observance of certain statutes at the University of Montpellier.[2682] James II employed him in 1306-1307, and he corresponded with Clement V and Philip IV. In 1308-1309 he interpreted a dream for Frederick of Sicily and with him concocted a scheme for a crusade and reform of the church, in pursuance whereof he went to Rome, Barcelona, and Avignon, and carried letters back and forth between James and Frederick.[2683] Arnald had been with Clement V at Bordeaux and seems to have been with him again at Avignon in 1309, but he does not appear to have been the pope’s official physician,[2684] although very probably he rendered him some medical service. About this time he also seems to have written several treatises in medicine and alchemy, including his Preservation of Youth, for King Robert at Naples. Raymond Lull speaks of meeting him there and acknowledges his debt to his friend Arnald for one of his “Experiments.” A letter of December 6, 1311, from Escarrer at Naples to King James shows that Arnald died in the closing months of that year.[2685] In 1312 we find Clement V advertising by public letter for a medical treatise by Arnald intended for his perusal but which the death of the author had prevented from reaching its destination.
