Almagesti (tr. George of Trebizond)

Text   ‘(Vatican, BAV, Vat. lat. 2054) (1r-3v) [preface to sixtus iv] Ad sanctissimum dominum nostrum Sixtum Quartum pont<ificem> max<imum>, Andree Trapezuntii, Georgii filii, in paternam Almagesti Ptolomaei traductionem prefatio. Evolventi mihi nuper libros patris mei, Georgii Trapezuntii, viri optimi et omni doctrinarum genere insignis — Arthaxerxem offerentis studium magnopere comprobasse. (3v-20r) [book i] Magne compositionis Ptolomei libri ad Georgio Trapezuntio e Graeco conversi incipiunt. Peroptime mihi videntur, o Syre, qui bene philosophati sunt, speculativam philosophie partem ab activa separasse. Nam etsi activae accidat parti — poenitus omnibus accidunt. Finis primi libri feliciter. (20v-45v) [book ii] Incipit liber secundus Ptolomei Magne compositionis. De universali orbis terrarum qui a nobis habitatur. Cap<itulum> I. Quoniam iam in primo huius constitutionis libro ea perstrinximus — quando occidentalior quam Alexandria est. Finis secundi libri feliciter. (45v-61r) [book iii] Incipit liber tertius. De magnitudine anni temporis. Capitulum primum. Cum in superioribus quae universaliter ac mathematice de caelo — et sexagesimas octo proxime [followed by the erased lines]. Finis tertii libri M. C. P. (61r-78v) [book iv] Incipit liber quartus Ptolomei Magnae compositionis. A quibus observationibus Lune accidentia examinanda sunt. Cum iam in precedenti libro que Solis motui accidunt — rationibus nostris convenire videamus. Finis quarti libri. (78v-99r) [book v] Incipit liber V Magne compositionis Claudii Ptholomei. De constructione instrumenti quod astrolabium vocant. Verum ad oppositiones quidem atque coniunctiones et eclipsis que in eis — nobis erant invenienda (99v-119r) [book vi] Incipit liber VI Magnae compositionis Ptolomei. De coniunctionibus Solis et Lunae. Cum vero deinceps de coniunctionibus atque oppositionibus eclipticis Lunae ac Solis — inclinationem facture sint. (119r-137r) [book vii] Incipit liber VII feliciter Ptolomei. Quod stelle non erratice semper eundem inter se situm servant. Quoniam in superioribus tam recte quam declivis — sexte 2. Finit VII liber. (138r-148r) [book viii] Incipit liber octavus. Expositio tabularis constellationis hemisperii australis. Fulgens earum que sunt in extremitate — et Lune in ipsis ex parte declinationibus. (148v-168r) [book ix] Liber VIIII Magne compositionis Ptholomei incipit. De ordine globorum Solis, Lune ceterorumque stellarum erraticarum. Verum que de fixis summatim quantum ab apparentibus — ab observationis gradibus Libre sex. (168r-181r) [book x] Incipit liber X Magne compositionis Ptolomei. Demonstratio maxime longitudinis stelle Veneris. Sed Mercurii quidem suppositionis inequalitatum — tempore gradus Cancri 16.40. (181r-198v) [book xi] Liber XI Magne compositionis Ptolomei incipit. Demonstratio excentricitatis et maxime longitudinis stelle Iovis. Demonstratis iam motibus periodicis et locis — ad apparentem eius locum perveniemus. (199r-213v) [book xii] Incipit liber XII Magne compositionis Ptolomei. De iis que premittuntur ad regressus planetarum demonstrandos. His demonstratis sequitur ut regressus etiam qui singulis quinque — (213r) quintus vespertinas. Est autem tabula haec [followed by the table f. 213v] (214r-232r) [book xiii] Incipit XIII liber et ultimus Magne compositionis Pto<lomei>. De suppositionibus que ad motus latitudinis quinque planetarum pernitent. Verum cum ad absolvendum quinque planetarum doctrinam duo hec restent — ad ostentationem accomodatus petebat pertractatis idoneum hic modum ac finem haec est compositio consecuta.’

Origin Translated from the Greek in 1451 by George of Trebizond, who simultaneously worked on the commentary (C.1.14). The translation was first addressed to Pope Nicholas V (1397-1455), who had commissioned it. Later, it was addressed to Mehmed II (in 1466) and, after George of Trebizond died, his son, Andreas, dedicated both the translation and the commentary to Pope Sixtus IV (in 1480-1481).
