Geomancies are of frequent occurrence in libraries of medieval manuscripts.[317] Many are anonymous[318] but others bear the names of noted men of learning. The art must have had great currency among the Arabs,[319] for not only are treatises current in Latin under such names as Abdallah,[320] Albedatus,[321] Alcherius,[322] Alkindi,[323] and Alpharinus,[324] but almost every prominent translator of the time seems to have tried his hand at a geomancy. In the manuscripts we find geomancies attributed to Gerard of Cremona,[325] Plato of Tivoli,[326] Michael Scot,[327] Hugo Sanctelliensis,[328] William of Moerbeke,[329] William de Saliceto of Piacenza,[330] and Peter of Abano,[331] and even to their medical confrère and contemporary, Bernard Gordon, who is not usually classed as a translator.[332] Some of these, however, were translators from the Greek or the Hebrew rather than Arabic, and some of the geomantic treatises in the manuscripts claim an origin from India.[333] But a Robert or Roger Scriptoris who compiled a geomancy towards the close of the medieval period thinks first among his sources of “the Arabs of antiquity and the wise moderns, William of Moerbeke, Bartholomew of Parma, Gerard of Cremona, and many others.”[334] These other geomancies are not necessarily like the _Experimentarius_ of Bernard Silvester[335] and we shall describe another sort when we come to speak of Bartholomew of Parma in a later chapter. [Sidenote: Interest of statesmen and clergy in the art.] In the fifteenth century such intellectual statesmen as Humphrey, Duke of Gloucester, and Henry VII of England displayed an interest in geomancy, judging from a manuscript _de luxe_ of Guido Bonatti’s work on astrology which was made for Henry VII and contains a picture of him, and also Plato’s translation of the geomancy of Alpharinus and geomantic “tables of Humphrey, duke of Gloucester.”[336] The interest of the clergy in this superstitious art is attested not only by the translation of such a person as William of Moerbeke, who was papal penitentiary and later archbishop of Corinth, but by a geomancy which we find in two fifteenth century manuscripts written by Martin, an abbot of Burgos, at the request of another abbot of Paris.[337] Treatises on geomancy continue to be found in the manuscripts as late as the eighteenth century, that of Gerard of Cremona especially. FOOTNOTES: [261] Clerval, _Les Écoles de Chartres_, Paris, 1895, pp. 158-63. The point was for a time contested by Ch. V. Langlois, “Maître Bernard,” in _Bibl. de l’École des Chartes_, LIV (1893) and by Hauréau. The two Bernards are still identified in EB, 11th edition, while Steinschneider (1905), p. 8, still identified Bernard of Chartres with the author of _De mundi universitate_.
