[In these missions, from the year 1718, multitudes of infidels were baptized and hundreds of apostates reclaimed. Prominent among the laborers therein were Fray Juan Velloxin, Fray Antonio Leon and a brother of his (who died worn out by the fatigues of his work), Fray Manuel Calvo, and Fray Francisco Alvarez. [50] During that time four villages of converts were formed--Ururin, Lupao, Umingan, and Tayog, in which the natives lived in very Christian fashion, their numbers increasing with new conversions. Mozo relates several instances of the opposition made by the devil to this work.] CHAPTERS X, XI Missions to Visayas Having now made known the triumphs secured in this present century in the great island of Luzon, it is right that we say something of the missions which the province maintains in the various islands which are called Visayas; and, in order that the reader may better understand the pious labors which are being endured in the conversion of the infidels therein to our holy faith, it will be very proper to say something about the customs of the said peoples, and of the places where they dwell, even though it be without enlarging much thereon. Commencing with the latter point, I relate how in two islands, called Zebu and Panay, there are some exceedingly dense woodlands, and mountain districts more rugged than can be described; for they are so impenetrable, and so thick with undergrowth, that it is impossible to make a step forward without the utmost toil, and even danger, especially for those who are ignorant of the path, such as it is--which the natives know, and by which they go down, when it suits them, to look for some things which they need. In the said mountains dwell a people who are called Mundos; [51] they have the same characteristics of fierceness and barbarism as those of whom we have spoken in preceding missions, but they have besides this a peculiarity which renders them intractable, for they have among them some fearful wizards, who by conversing with the demon do things which cause terror, and who are able to render credible much of what is regarded as fabulous. [Here our author cites various writers to show how prevalent was witchcraft in the ancient times.]
