Note 313 — Chapter XXXIX

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.
