[348] Pitra, 7-8, “Et ego testimonio hominis illius quem ut in prioribus visionibus praefata sum occulte quaesieram et inveneram et testimonio cuiusdam puellae mihi assistentis manus ad ascribendum posui.” [349] Vincent of Beauvais, _Speculum historiale_, XXVII, 83, and other actors cited from the _Acta Sanctorum_ in Migne, col. 197. [350] This may be a further explanation of the use of German words in some of her works and their absence in others. [351] Migne, 17, 19-20, 73-74, 93, 101. [352] It is, however, the order in at least one of the MSS, Wolfenbüttel 3591, 14th century, fols. 1-174, except that the second book is called Of rivers instead of, Of elements: “_B. Hildegardis Physica seu liber subtilitatum de diversis creaturis, scilicet f. 2 de herbis, f. 62 de fluminibus, f. 67 de arboribus, f. 90 de lapidibus preciosis, f. 106v de piscibus, f. 120 de volatilibus, f. 141 de animalibus, f. 162 de vermibus, f. 168 de metallis._” [353] It was, however, subdivided into three parts, treating respectively of fish, fowl, and other animals. [354] The variety and confusing order of its contents may be best and briefly indicated by a list of chapter heads (pp. 33-52): _De Adae casu_, _de spermate_, _de conceptu_, _quare homo hirsutus est_, _de reptilibus_, _de volatilibus_, _de piscibus_, _de conceptus diversitate_, _de infirmitatibus_, _de continentia_, _de incontinentia_, _de flegmaticis_, _de melancholis_, _de melancholice morbo_, _de elementorum commixtione_, _de rore_, _de pruina_, _de nebula_, _quod quatuor sunt elementa tantum_, _de anima et spiritibus_, _de Adae creatione_, _de capillis_, _de interioribus hominis_, _de auribus_, _de oculis et naribus_, _quod in homine sunt elementa_, _de sanguine_, _de carne_, _de generatione_, _de Adae vivificatione_, _de Adae prophetia_, _de animae infusione_, _de Adae somno_, _de Evae malitia_, _de exilio Adae_, _quare Eva prius cecidit_, _de diluvio_, _quare filii Dei_, _de lapidum gignitione_, _de iri_, _de terrae situ_, _quod homo constat de elementis_, _de flegmate diversitate_, _de humoribus_, _de frenesi_, _de contractis_, _de stultis_, _de paralysi_. [355] _Causae et curae_, pp. 20 and 30. [356] Migne, 403-4. [357] Migne, 791-95. [358] _Subtilitates_, II, 3 (Migne, 1212), _Mare flumina emittit quibus terra irrigatur velut sanguine venarum corpus hominis_. [359] _Subtilitates_, II, 5 (Migne), _Rhenus a mari impetu emittitur_. Singer (p. 14) is so non-plussed by this that he actually interprets _mari_ as the lake of Constance, and asks, questioning Hildegard’s authorship of the _Subtilitates_, “How could she possibly derive all rivers, Rhine and Danube, Meuse and Moselle, Nahe and Glan, from the same lake, as does the author of the _Liber subtilitatum_?” That all waters, fresh or salt, came originally from the sea is asserted in the _Secretum Secretorum_ of the Pseudo-Aristotle, as edited by Roger Bacon: Steele (1920), p. 90. [360] _Causae et curae_ (1903), p. 24.
