[312] Digby 46, fol. 5v; Sloane 3554, fol. 12r. [313] I have described the _Prenostica_ as it is found in Digby 46, fol. 40r-, with a picture at fol. 41v of Socrates seated and Plato standing behind him and pointing. Ashmole 304 has the same text and picture; and the text is practically the same in Sloane 3857, fols. 196-207, “_Documentum subsequentis considerationis quae Socratica dicitur_.” In Additional 15236, 13-14th century, fols. 95r-108r, the inquirer is first directed to implore divine aid and repeat a Paternoster and Ave Maria, and some details are slightly different, but the general method is identical. The final answers are given in French. In BN 7420A, 14th century, fol. 126r- (or clxxxxvi, or col. 451), “_Liber magni solacii socratis philosophi_” is also essentially the same; indeed, its opening words are, “_Pronosticis Socratis basilii_.” Preceding it are similar methods of divination, beginning at fol. 121v (or clxxxxii or col. 440), “_Si vis operare de geomancia debes facere quatuor lineas...._” Evidently the following is also our treatise: CU Trinity 1404 (IV), 14-15th century, _Iste liber dicitur Rota fortune in qua sunt 16 questiones determinate in pronosticis sententiat’_. (sic) _basilici que sub sequentibus inscribuntur et sunt 12 spere et 16 Reges pro iudicibus constituti et habent determinare veritatem de questionibus antedictis cum auxilio sortium_. James (III, 423) adds, “The questions, tables, spheres, and Kings follow....” Our treatise is also listed in John Whytefeld’s 1389 catalogue of MSS in Dover Priory, No. 409, fol. 192v, _Pronostica socratis phi_. [314] These tracts of divination are found in Digby 46, fols. 52r-92r, and partially in Ashmole 304, Sloane 3857, and Sloane 2472. [315] Sloane 2472, fol. 22r. [316] The word seems to be regularly so spelled in the middle ages, although modern dictionaries give only aeromancy. [317] For instance, at Munich the following MSS are devoted to works of geomancy: CLM 192, 196, 240, 242, 276, 392, 398, 421, 436, 456, 458, 483, 489, 541, 547, 588, 671, 677, 905, 11998, 24940, 26061, 26062. [318] For instance, Amplon. Quarto 174, 14th century, fol. 120, _Geomancia parva_; Qu. 345, 14th century, fols. 47-50, _geomancia cum theorica sua_; Qu. 361, 14th century, fols. 62-79, five treatises; Qu. 365, fol. 83; Qu. 368, 14th century, fol. 30; Qu. 374, 14th century, fols. 1-60; Qu. 377, 14th century, fols. 70-76; Amplon. Octavo 88, 14th century, fols. 5-10; Amplon. Duodecimo 17, 14th century, fols. 27-35. Harleian 671; 4166, 15th century; Royal 12-C-XVI, 15th century; Sloane 887, 16th century, fols. 3-59; 1437, 16th century; 2186, 17th century; 3281, 13-14th century, fols. 25-34, “_Liber 28 iudicum_” or “_Liber parcarum sive fatorum_.” [319] Additional 9600 is a geomancy in Arabic, and Addit. 8790, _La Geomantia del S. Christoforo Cattaneo, Genonese, l’inventore di detta Almadel Arabico_.
