An attractive collection of five of Angeli's scientific writings, all first editions, and including his most important writings on fluids. Angeli (1623-97), studied mathematics under Cavalieri at Bologna and edited his teacher's Exercitationes Geometricae Sex (1647). In 1663, Angeli was offered the prestigious professorship of mathematics at the University of Padua, a post that had been held by Galileo, and which Angeli filled until his death. I-IV. These four works, a complete set, written in the style "of dialogues that reflect Galileo's style, form a lively but cautious polemic on the problems of the Ptolemaic and Copernican cosmological systems. G.B. Riccioli, in his Almagestum novum, had formulated some arguments against the Copernican system. Angeli asserted that 'the earth is motionless, but Riccioli's reasons do not prove the point,' and he devoted the first of these studies (1667) to demonstrating that Riccioli's anti-Copernican arguments were without foundation. Angeli replied to Riccioli's arguments with another work in 1668. G.A. Borelli, who later participated in the polemic, rejected Riccioli's arguments, and pointed out that if Angeli's views were correct, falling bodies should follow a vertical trajectory in the hypothesis of the earth's motion as well."-D.S.B., I, pp. 164-65. V. Angeli's Della gravità dell'aria e fluidi "is largely experimental in character. In it he examines the fluid statics, based on Archimedes's principle and on Torricelli's experiments. It also contains theories of capillary attraction."-ibid., p. 165. In Angeli's works on physics, there are many references to Galileo's mechanics, as well as his acceptance of the experimental method. Fine copies.
