distribution of manuscripts of his translations in European libraries indicates that they were widely influential. [Sidenote: A contemporary memorial of Gerard of Cremona.] The best source for the life and works of Gerard of Cremona[240] (1114-1187) is a memorandum attached by his friends to what was presumably his last work, a translation of the _Tegni_ of Galen with the commentary of Haly, in imitation of Galen who in old age was induced to draw up a list of his own works. Gerard, however, is already dead when his associates write, having worked right up to life’s close and passed away in 1187 at the age of seventy-three. They state that from the very cradle he was educated in the lap of philosophy, and that he learned all he could in every department of it studied among the Latins. Then, moved by his passion for the Almagest, which he found nowhere among the Latins, he came to Toledo. There, beholding the abundance of books in every field in Arabic and the poverty of the Latins in this respect, he devoted his life to the labor of translation, scorning the desires of the flesh, although he was rich in worldly goods, and adhering to things of the spirit alone. He toiled for the advantage of all both present and future, not unmindful of the injunction of Ptolemy to work good increasingly as you near your end. Now, that his name may not be hidden in silence and darkness, and that no alien name may be inscribed by presumptuous thievery in his translations, the more so since he (like Galen) never signed his own name to any of them, they have drawn up a list of all the works translated by him whether in dialectic or geometry, in “astrology” or philosophy, in medicine or in the other sciences.[241] [Sidenote: Account by a pupil of his astrological teaching.] Another contemporary picture of Gerard’s activity at Toledo is provided us by the Englishman, Daniel of Morley, or _de Merlai_, who went to Spain to study the sciences of the _quadrivium_. He tells how Gerard of Toledo (_Gerardus tholetanus_), interpreting the Almagest in Latin with the aid of Galippus, the Mozarab,[242] asserted that various future events followed necessarily from the movements and influences of the stars. Daniel was at first astounded by this utterance and brought forward the arguments against the _mathematici_ or astrologers in the homily of St. Gregory. But Gerard answered them all glibly. It should perhaps be added that in another passage Daniel without mentioning Gerard speaks of setting down in Latin what he learned concerning the universe in the speech of Toledo from Galippus, the Mozarab.[243] Gerard’s translation of the Almagest seems to have been completed in 1175,[244] but meanwhile in Sicily an anonymous translation from the Greek had appeared, probably soon after 1160. Of it we shall presently have something to say. Gerard’s version was, however, the generally accepted one, as the number of manuscripts and citations of it show.
