(54) For the relation of these discoveries to Copernicus's work, see Delambre, Histoire de l'Astronomie moderne, discours preliminaire, p. xiv; also Laplace, Systeme du Monde, vol. i, p. 326; and for more careful statements, Kepler's Opera Omnia, edit. Frisch, tome ii, p. 464. For Copernicus's prophecy, see Cantu, Histoire Univerelle, vol. xv, p. 473. (Cantu was an eminent Roman Catholic.) III. THE WAR UPON GALILEO. On this new champion, Galileo, the whole war was at last concentrated. His discoveries had clearly taken the Copernican theory out of the list of hypotheses, and had placed it before the world as a truth. Against him, then, the war was long and bitter. The supporters of what was called "sound learning" declared his discoveries deceptions and his announcements blasphemy. Semi-scientific professors, endeavouring to curry favour with the Church, attacked him with sham science; earnest preachers attacked him with perverted Scripture; theologians, inquisitors, congregations of cardinals, and at last two popes dealt with him, and, as was supposed, silenced his impious doctrine forever.(55) (55) A very curious example of this sham science employed by theologians is seen in the argument, frequently used at that time, that, if the earth really moved, a stone falling from a height would fall back of a point immediately below its point of starting. This is used by Fromundus with great effect. It appears never to have occurred to him to test the matter by dropping a stone from the topmast of a ship. Bezenburg has mathematically demonstrated just such an aberration in falling bodies, as is mathematically required by the diurnal motion of the earth. See Jevons, Principles of Science, pp. 388, 389, second edition, 1877. I shall present this warfare at some length because, so far as I can find, no careful summary of it has been given in our language, since the whole history was placed in a new light by the revelations of the trial documents in the Vatican Library, honestly published for the first time by L'Epinois in 1867, and since that by Gebler, Berti, Favaro, and others.
