Erfurt, Universitäts- und Forschungsbibliothek, Amplon. F. 375

s. XIV (middle to second half acc. Schum). Or.: probably Paris, for the scribe appears to have used MS Paris, BnF, lat. 16200 (see f. 85r-103r below). Prov.: Amplonius Rating (1363-1435); Erfurt, Collegium Porta Coeli in 1412.

Paper, 170 f., one main hand or two similar hands alternately (several hands according to Schum). A section may be missing after f. 84v, at the bottom of which we read ‘Incipit septimus liber Euclidis’. Numerous glosses on f. 18r-32r (including one in Greek on f. 18r), 85r-87r, 93v-94v and 97r-97v apparently by the main scribe(s). No or sporadic glosses elsewhere.

Mathematics and astronomy: Thomas Bradwardine, Geometria speculativa (1r-15v); Thomas Bradwardine (?), Arithmetica ‘Horum que sunt aliud est continuum…’ (15v-17v, continued on 88v-92v); Euclid, Elementa, ed. Campanus of Novara, Books I-VI (18r-84v); Ptolemaica (85r-88r); Thomas Bradwardine (?), Arithmetica (88v-92v, see 15v-17v above); Ptolemaica (93r-112v, 113r-126v and 127r-129v); ‘Aux et oppositum augis, centrum terre et centrum ecentrici…’ (131ra-134rb); ‘Tres circulos in astrolapsu descriptos…’ (135ra-135vb); ‘Et ut melius intelligamur qualiter coniunctiones Saturni et Iovis…’ (136ra-137rb); ‘Omnis trianguli cuius latera sunt nota…’ (137va-137vb); comm. on Sacrobosco’s De sphera (138ra-169vb); notes (170r-170v). Blank: 95v, 108r, 130r-130v, 134v.

85r‑88r and 93r‑112v

‘Summa vero principiorum que oportuit nos incipere — duobus angulis rectis. Illud est quod declarare nos oportuit.’

= Ptolemy, Almagesti (tr. Gerard of Cremona) (A.1.2), I.9-II.12. Tables are incomplete or missing. F. 101, of smaller size, is an insertion containing notes on the Almagest by the scribe. Substantial glosses by the scribe, including excerpts from the Almagesti minor (see below). These glosses are clearly related to the text that follows on f. 113r-126v (see Zepeda, The Medieval Latin Transmission, 170 and 184; Zepeda, The First Latin Treatise, 78).

(85r‑103r)

‘Parvi Almagesti breviato cum commento. Data circuli dyametro latera decagon — non erunt ascensiones omnium.’

= Almagesti minor (C.1.3), excerpts I.1-14, I.17, II.2-5 and II.14-15, as glosses to the Almagest (see above) on f. 85r-86v, 93v-94v, 97r-97v and 103r. These gloses share several unique features with the glosses found in MS Paris, BnF, lat. 16200 (see) and are therefore likely to have been copied from that MS.

113r‑126v

‘Commentum super Almagesti Ptholemei [title in the upper margin by the scribe]. Data circuli dyametro… Pro probacione istius proposicionis supponitur quod linea divisa — erit angulus DEA notus orientalis super orizontem, quod est propositum.’
