456 REVIEWS OF BOOKS July in a hardly less famous lectionary, 2 A. xx. There are several other traces of the influence of Capuan observances in England. The description of 15 B. ix needs supplementing from Bubnov's Gerberti Opera Mathematica, pp. xxxvi-xxxviii, where more of its contents is identified. Bubnov prints art. 18, on the astrolabe, which he inclines to attribute to Gerbert's corre- spondent, Lupitus of Barcelona (pp. 370-5). 5 D. i-iii. The statement that Ernulf, prior of Canterbury, abbot of Peterborough, and bishop of Rochester, was prior of Rochester before he became prior of Canterbury in 1096 rests on a reference by Wharton l to a charta autographa at Canterbury which has not since been verified. It looks as though in the sentence Arnulfi prioris Roffensis the last word was inserted in the margin in order to identify the prior of Canterbury with the future bishop of Rochester, and that this note was erroneously taken as part of the text. 8 A. xxi. The author of the De Contemptu Mundi, printed as the work of Nigel Wireker, is given in a Rouen manuscript as ' Claudianus '. This, it is suggested, ' may be interpreted as meaning that it is the work of a Gloucester monk '. One would like to have other evidence of such a formation from ' Claudiocestria '. At any rate the name may be brought into connexion with the Antidaudianus of Alan of Lille The correct title of the Decretum of Gratian is not Concordantia discordantium Canonum (as given under 9 C. iii and 10 C. iv) but Concordia,* as in 9 F. vi. It may be suggested that 5 F. x, a twelfth-century manuscript of Caesarius and other authors, may perhaps be traced not to Wallingford but, like 11 E. i, to St. Albans, of which Wallingford was a cell. Under 2 D. viii, a work by Alexander Neckam is described as Isagoge in Aries, with a note that in 5 C. v it appears as Corrogationes Promethei. The latter, as Paul Meyer has pointed out, 3 is the title by which Neckam himself cited the work. A commentary on the Epistle to the Romans bears no author's name in 8 C. v, art. 4, but in the index is said to be ' apparently by ' Gilbert of La Porree. The University College, Oxford, MS. Ixxii, fo. 65, contains a copy of the commentary on all the Pauline epistles headed Comentum magistri Gilberti. This Gilbert, since Boston of Bury, has been distinguished as of Hoyland, but the surname is not certain. Under 5 A. xii, art. 20, ' Robertus Lincoln, episcopus ad dom. papam ', it should have been noticed, as is done under 6 E. v, art. 9, that the letter is addressed not to Pope Innocent IV but? to ' magister Innocentius, papal scriptor '. But Charles Jourdain's criticism makes the authenticity of the letter more than doubtful. The description of Henry de Gandavo as ' Goethals ' (10 D. vi, 11 C. x), has been shown by Father Ehrle 4 to be based on an unauthentic modern tradition. The Compendium Medicine of Gilbertus Anglicus (12 G. iv) has been wrongly attributed to Gilbert L'Aigle, but this man was not ' a later physician ', for he is mentioned by Ralph Coggeshall. ' Cotton ' cited in notes to 7 D. vii is probably the popular Franciscan divine Robert Cowton. Attention may be drawn to a number of points, of various degrees of interest, as suggestions for students in search of anecdota or materials not yet fully examined. .. 6 A. v, art. 6, catalogue of the library of the abbey of Lobbes, in the diocese of Cambray, in 1049. This is cited, but not printed, by Gottlieb, Mittelalterliche Siblio- theken. 7 D. xxv, a book of chronological and other miscellanies. The suggestion that it is a copy of a work by Adelard of Bath is worth pursuing. 11 A. v, part of Abailard's Sic ct non, apparently from an unknown recension. 1 Anglia sacra, i. 292.
