Our only source for the nature of Hippocrates' work is Simplicius, who comments on Artistotle's remark that the inference from the quadrature of the lune to the quadrature of the circle is an example of faulty reasoning. In this article two groups of Hebrew texts are translated and analyzed. The first come from mathematical treatises, and their contents show that materials similar to those cited by Simplicius were translated and read in the later medieval period. The second group comprises constructions found as comments to the Averroean corpus, and they attest to the existence of a more limited tradition preserving simple constructions that were necessary to the understanding of Averroes' commentaries on Aristotle. Levi ben Gerson's reconstruction of the quadrature is wholly original. La quadrature de la lunule, par Hippocrate, fut une des premi\u00e8res r\u00e9alisations de la g\u00e9om\u00e9trie gr\u00e8cque. Notre seule source concernant l'oeuvre d'Hippocrate est Simplicius, qui commente une remarque d'Aristote, selon laquelle il est fautif de se servir de la quadrature de la lunule pour conna\u0131\u0302tre la quadrature du cercle. Dans cet article nous traduisons et analysons deux ensembles de textes hebra\u0131\u0308ques portant sur ce sujet. Un premier ensemble renferme des textes qui proviennent de trait\u00e9s math\u00e9matiques et qui, par leur contenu, indiquent que des mat\u00e9riaux s'apparentant \u00e0 ce que cite Simplicius \u00e9taient connus au Moyen \u00c2ge. Le second ensemble comprend des textes qui sont ins\u00e9r\u00e9s dans des commentaires des \u00e9crits d'Averro\u00e8s: ils attestent l'existence d'une tradition, d'une port\u00e9e plus limit\u00e9e, qui conserve des constructions simples qui \u00e9taient n\u00e9cessaires \u00e0 la compr\u00e9hension de certains passages des commentaires d'Averro\u00e8s. La reconstruction de la quadrature de la lunule qu'offre L\u00e9vi ben Gershon est enti\u00e8rement originale. La quadratura della lunula, risolta da Ippocrate, fu uno dei primi successi della geometria greca. L'unica fonte relativa all'opera di Ippocrate e un'annotazione di Simplicio, a commento di un'osservazione di Aristotele, secondo cui servirsi della quadratura della lunula per risolvere la quadratura del cerchio e un esempio di inferenza indebita. Nel presente articolo sono tradotti e analizzati due gruppi di testi ebraici relativi all'argomento. Il primo e desunto da trattati matematici, che monstrano come materiali simili a quelli impiegati da Simplico fossero noti in et\u00e0 medievale. Il secondo gruppo e costituito da testi inseriti nei commenti agli scritti di Averroe, che attestano l'esistenza di una tradizione pi\u00f9 limitata, ma che ha conservato alcune construzioni semplici, necessarie alla comprensione di passi dei commenti di Averroe. Del tutto originale risulta la ricostruzione della quadratura della lunula proposta da Levi ben Gershon.","btype":3,"date":"1996","language":"English","online_url":null,"doi_url":null,"ti_url":null,"categories":[{"id":19,"category_name":"Cosmology","link":"bib?categories[]=Cosmology"},{"id":8,"category_name":"Jewish Averroism","link":"bib?categories[]=Jewish Averroism"}],"authors":[{"id":612,"full_name":"Yitzhak Tzvi Langermann","role":1}],"works":[],"republication_of":null,"translation_of":null,"new_edition_of":null,"book":null,"booksection":null,"article":{"id":427,"journal_id":null,"journal_name":"Historia mathematica","volume":"23","issue":"1","pages":"31\u201353"}},"sort":[1996]}

For this purpose, Aristotle's book \u201cOn the Heaven,\u201d in which he explained the eternity, uniqueness and movement of the universe, occupied a place of special importance. But the Aristotelian philosopher had a hard time holding his own in the face of contradictions within the book and with respect to Aristotle's later works. In his early Compendium, later Paraphrase, and final Long Commentary of De Caelo, Ibn Rushd continued the efforts of the Hellenistic commentators in order to integrate all the elements of his doctrine into a unified system, to harmonize his early cosmology with his later Metaphysics - the early doctrine of natural movement of the elements, and of the self-moving star-souls (a Platonic element), with the doctrine of potency and actuality and the theory of the First Mover - and to uphold his models of homocentric planetary spheres against the mathematical paradigm of Ptolemaic astronomy. By insisting throughout on demonstrative arguments based on rational principles, he asserted the philosophers' claim to irrefutable truth.","btype":3,"date":"1995","language":"English","online_url":null,"doi_url":null,"ti_url":null,"categories":[{"id":19,"category_name":"Cosmology","link":"bib?categories[]=Cosmology"},{"id":21,"category_name":"Aristotle","link":"bib?categories[]=Aristotle"}],"authors":[{"id":203,"full_name":"Gerhard Endress","role":1}],"works":[],"republication_of":null,"translation_of":null,"new_edition_of":null,"book":null,"booksection":null,"article":{"id":420,"journal_id":null,"journal_name":"Arabic Sciences and Philosophy","volume":"5","issue":null,"pages":"9\u201349"}},"sort":[1995]}
