lii INTRODUCTION ed a number of those addressed to Fracastorius; some are absurd, for instance that of Lanchius, who declares that the shades and the ghost of Catullus himself stood amazed and admiring while Fracastorius sang to them his poem Syphilis; nearly all say that he was the Virgil of his century, just as they had said it of Sannazaro in 1530; and that all Nature wept at his death. "TThe aucior »iae praises, above all, the epigram of Adamo Fumani of Verona, Secretary of the Council of Trent, which ends in the typical manner: Ad tristem acerbae mortis ejus nuntium Vicina flevit ora, flerunt ultimae Gentes, perisse musicorum candidum Florem, optimarum et lumen artium omnium.

Bruno, who calls him Fracastorio, thus Italianis— ing his Latin name, makes him an interlocutor in four of his five Italian Dialogues, De /infinio universo ed mondi, On the Infinite Universe and its Worlds, a work which was written 1584—85 and was placed on the Indez Ezpurgatorius in 1603.

Whatever Fra— castorius may have thought about this,he would certainly not have dared to utter, in his lifetime, a doctrine that would be regarded by the Church as fatal to their own of the Fall and the Redemption. In Dialogue I, however, Fracastorius is made to say that they are not offering such views to the masses, but only to the learned, and that learned and truly religious theolo— gians have never wished to interfere with the freedom of science. "TThe theologians who burned Bruno at the stake in 1600 were presumably unvwilling to include themselves in such a category. As an interlocutor in these Dialogues, Fracastorius is calm and dignified, in striking contrast with the violent, vituperative and strictly orthodox Burchio; he sometimes uses Latin in his
