Text ‘(Pisa, BU, 386) Magnae constructionis Claudii Ptolomei liber primus cum commentariis Theonis Alexandrini a Georgio Fleming Hibernio ex Graeco idiomate in latinam linguam conversus et ab Alexandro Marchetti Pisiae phylosophiae professore ordinario accuratissime emendatus, cui accesserunt etiam eiusdem breviores quaedam animadversiones in Theonis commentarium.

Origin Translated from Greek by the Irishman George Fleming, with corrections by Alessandro Marchetti (1633-1714), professor of philosophy and mathematics at the University of Pisa. The translation contains Book I only and is interspersed with Theon of Alexandria’s commentary. The text is followed by Alessandro Marchetti’s notes, which end abruptly in the only known MS. Halma and Rome, who did not know the Pisa MS, were aware of this translation through literary evidence (yet Halma thought that it never existed).

Bibl. N. Halma, Commentaire de Théon d’Alexandrie sur le premier livre de la composition mathématique de Ptolémée, Paris, 1821, viii; A. Rome, Commentaires de Pappus et de Théon d’Alexandrie sur l’Almageste, Vaticano, 1931-1943, 3 vols, I, vii.

Ed. None, but a letter by Pier Matteo Maggio, dated Florence 29 September 1703, refers to a printed version published by Marchetti, see MS Boncompagni 218.
