Abstract

The period considered in this chapter (about ten centuries long) is that which, in its final part, is close to the time of Galileo and then, also in the light of the theories on the importance of some medieval works, it is essential to make clear in what context Galileo worked.

  1. 1.

  2. 2.

    See Ernst Mach: The Science of Mechanics: A Critical and Historical Account of its Development—Translated by T. J. Mc Cormac—Open Court Classics 1988. (The first edition in German language was published in Prague in 1883).

  4. 4.

    One of the first works of this type was the Histoire de la Mécanique of René Dugas (Neuchâtel, 1950), which was published with a preface by Louis De Broglie and was translated in English some years later (the English translation was reprinted by Dover in 1988). To this, Dugas added La mécanique au XVII e siècleDès antécédents scolastique à la pensée classique (Neuchâtel, 1954).

  5. 5.

    Unfortunately, Mayer’s work is almost unknown out of the exclusive circle of the specialists who deal with the history of philosophy and medieval science. Maier took her degree in Germany and then, after having completed her studies at Zurich and Berlin, passed in Italy in 1936 to look for manuscripts of Leibnitz (entrusted with a mandate by the Prussian Academy of Sciences). Starting from 1937 she resided in Italy almost consecutively and there published the greater part of her writings. She wrote always in German and this happened when by that time the scientific literature regarding the subjects she dealt with was for the most part in English language. Her writings were almost all published (in German language) by the Edizioni di Storia e Letteratura—Roma—since the fifties of the last century. Only some decades later an English translation of a selection of her essays on the medieval sciences and Galileo was published: On the Threshold of Exact ScienceSelected Writings of Anneliese Maier on Late Medieval Natural Phylosophy, edited and translated with an Introduction by Steven D. Sargent —University of Pensilvania Press, 1982. For these reasons, as we said, her name has not crossed the border of the specialistic research and therefore the results of her research are known only through the quotations of the specialists.

  7. 7.

    In 1921, Favaro, on reviewing a work of a French author regarding the Italian though of XVI century, takes the opportunity to address accusations to Duhem. With regard to the studies of Duhem, he says: «… for having an exact enough opinion of the important question of which such studies show only one side, and perhaps the less important, it will not be inopportune to remind its highest origins, even if for this is necessary to unveil the back stage.» In substance, Duhem’s studies on the school of Parisian terminists and the consequent opinion on Galileo (only a continuator of theirs) would have been originated (through Cardinal Dechamps and abbot Mercier) by a directive of Pope Lion XIII for promoting the neo-scholasticism.

    Ibn-Badja is the first philosopher famous among the Arabs of Spain—he was born in Saragossa at the end of the XI century and died in Fez in 1138.

  13. 13.

    It is of a great interest, on the discussions regarding the Aristotelian physics in the Middle Ages, the long essay of E. A. Moody: Galileo and AvempaceThe dynamics of the leaning tower experiment—published in two parts in the Journal of the History of Ideas Vol. 12 (1951. 163–193, 375–422). We shall refer to this essay in Chap. III.

  18. 18.

    For this and a thorough discussion of the Liber de Motu, see E. Giusti: Alle origini della cinematica medievale: il Liber de Motu di Gherardo da Bruxelles (Bollettino di Storia delle Scienze Matematiche—vol. XVI, 199–240, 1996).

  19. 19.

    See the final edition of Clagett quoted in footnote 17, p. 64: «The proportion between the velocities of points is the same as that between the lines described in the same time».

  20. 20.

    See: J. Mazur: Zeno’s Paradox, Dutton, 2007. J. Mazur asserts that with Gerard one has to do, for the first time, with velocities considered as magnitudes and such an approach marks a turning point in the direction of the modern concept of istantaneous velocity. But neither Clagett, nor Giusti and not even Souffrin (who had dealt thoroughly with the concept of velocity) had made an assessment of this kind of the quoted passage of Gerard. The paper of Souffrin we refer to is the already quoted Sur l’histoire du concept de vitesse d’Aristote à Galilée—Medioevo—Rivista di Storia della Filosofia medievale—vol. XXIX (2004) pp 99–133.

    The editions in modern languages that one can look up are:

    For the overall work of Oresme and the scanty biographical data on him we refer to the article of Clagett in Charles Coulston Gillispie —Dictionary of Scientific Biography—Scribners, New York 1970—vol. 9, pp 223–230.

  32. 32.

    This interpretation has been suggested by Anneliese Maier in Die Vorläufer Galileis im 14 Jahrhundert , Roma 1949, p. 92. We refer the reader to Clagett’s work (op. cit. Chap. 7) and to the introduction of Sabine Rommevaux to the already quoted (see footnote 21) translation of Bradwardine’s treatise for further widening. Our very swift and schematic synthesis has only the aim of recording which was the conclusion achieved in the criticisms and corrections to the Aristotelian mechanics in the ambit of Mertonians. Swineshead and Dumbleton further elaborated into details the theory of Bradwardine (see Clagett, op. cit. Chap. 7).

    Taken from the eighth page (the pages are not numbered) of the dedication to abbot Gabriele Guzman of the Resolutio: «…ceterum quia cuique quod suum est reddi debet, nam pium et iustum est, Nicolaus Tartaleas mihi quattuor primos libros Euclidis solos legit, reliqua omnia privato labore et studio investigavi: volenti namque scire nihil est difficile».

  71. 71.

    Still today, the most complete study on this regard is given by the memoir of Giovanni Bordiga: Giovanni Battista Benedetti filosofo e matematico veneziano del secolo XVI—Atti dell’Istituto Veneto di Scienze, Lettere ed Arti, Tomo LXXXV, Parte seconda, pp 585–754 (1925–1926)—reprinted in 1985, with a bibliographic updating by Pasquale Ventrice on the occasion of the workshop on «Giovan Battista Benedetti e il suo tempo». In addition one can consult the entry of him (by Stillman Drake) in the vol. 1 (1970), pp. 604–609, of the Dictionary of Scientific Biography op. cit.

  72. 72.

    With regard to this, the most important studies are due to Carlo Maccagni (of whom we quote Le speculazioni giovanili “de motu” di Giovan Battista Benedetti (Pisa, Domus Galilaeana, 1967) and to Enrico Giusti (of whom we quote Gli scritti «de motu» di Giovan Battista Benedetti—Bollettino di Storia delle Scienze Matematiche, vol. XVII (1997) fasc. 1, pp 51–103.

  73. 73.

    See footnote 69.

  74. 74.

    For this, see: C. Maccagni Le speculazioni giovanili «de motu» … op cit. pp XXVII–XXXII. The book of Maccagni also contains excerpts of the dedicatory letter of the Resolutio omnium Euclidis problematum and the text of the two editions of the subsequent work Demonstratio .

    «Olim cum adhuc una essemus, magno me opere orasti obsecratusque es aliqua de motibus naturalibus speculatione sollicita conscriberem, idem quantum possibile est Mathematicis demonstrationibus muniens.»

  76. 76.

    The demonstration, based on the Archimedes’ principle had been perhaps suggested by the reading of the first treatise of Archimedes translated by Tartaglia in 1551.
