According to some authorities, the highest grade of these native hierophants bore among the Nahuas the symbolic name of “flower weavers,” _Xochimilca_, probably from the skill they had to deceive the senses by strange and pleasant visions.[30-*] In the south they were spoken of as “guardians,” which may have been derived from the classes of priests so-called in the Zapotec religion.[30-†] =19.= It will be seen from the above, that Nagualism, beginning in an ancient superstition dating back to the time of primitive barbarism, became after the Conquest a potent factor in the political and social development of the peoples among whom it existed; that it was the source from which was drawn and the means by which was sustained the race-hatred of the native American towards his foreign conquerors, smouldering for centuries, now and then breaking out in furious revolt and civil war. There is strong reason to suspect its power where, for obvious reasons, it has not been demonstrated. It has always been a mystery and a matter of surprise to the historians of Yucatan how rapidly spread the plans of the insurrection which secured lasting independence for the natives, after these plans had been agreed upon by the two chiefs, Antonio Ay and Cecilio Chi, at the remote rancho of Xihum, in July, 1847. Such unanimity of action could only have been possible through the aid of a powerful, well-disciplined and widespread secret organization. There can scarcely be a doubt they were the chiefs or masters of the redoubtable order of Nagualism in the Peninsula.[30-‡] There is no question that such was the case with the brief and bloody revolt of the Mayas in 1761. It suddenly broke out in a number of villages near Valladolid, Yucatan, headed by a full-blood native, Jacinto Can-Ek; but some of the participants afterwards confessed that it was the outcome of a conspiracy which had been preparing for a year. When the appointed day arrived, Jacinto boldly announced himself as the high priest of the fraternity of sorcerers, a master and teacher of magic, and the lineal successor of the famous ancient prophet, Chilan Balam, “whose words cannot fail.” In a stirring appeal he urged his fellow-countrymen to attack the Spaniards without fear of consequences. “‘Be not afraid,’ he exclaimed, ‘of their cannons and their forts; for among the many to whom I have taught the arts of magic (el arte de brujeria) there are fifteen chosen ones, marvelous experts, who by their mystic power will enter the fortress, slay the sentinels, and throw open the gates to our warriors. I shall take the leaves of the sacred tree, and folding them into trumpets, I shall call to the four winds of heaven, and a multitude of fighting men will hasten to our aid.’”[31-*]
