Note 359 — Chapter XL
Reading edition
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.
