Royal MS 12 D I

METALOGICA of John of Salisbury, afterwards (1176- 1180) Bishop of Chartres. In four books. The rubric heading is 'Iohannis Saresberiensis [ecclesie diaconi, written over an erasure) metalogicon primus liber incipit, but on the opposite page (f. 1 b) is a fuller rubric, 'Hunc librum scripsit Iohannes Salesbieriensis sancto Thome dum cancellarius esset, quia ei familiarissimus fuit et comes indiuiduus usque ad eiusdem maniris passionem et postea factus est Carnotensis episcopus'. As a matter of fact John composed the work in 1159, while chancellor to Archbishop Theobald. The form 'metalogicon' is probably meant by John for a genitive plural, and 'metalogicus' has no good authority. For another copy see 13 D. IV, art. 2. Printed, from a Cambridge MS., Paris, 1610, Leiden, 1639, and by Giles, Jo. Saresb. Opera, Oxford, 1848, v. Prologue beg. 'In humanis rebus nichil fere sic arbitror elimatum'; text, 'Aduersus insigne donum nature',

Vellum; ff. i + 81. 9³/₄ in. x 6¹/₂ in. XIII cent. Gatherings of 8 leaves numbered at the end. Double columns. Sec. fol. 'examinabis'. Initials in red, blue, and green. Old Royal press-mark 'no. 530' (Westm. invent. of 1542, Add. MS. 25469, f. 15); cat. of 666, f. 20; CMA. 8503.
