medieval-religion: Scholarly discussions of medieval religion and culture Chère Marjorie, Voici quelques pistes: Barthélemy l'Anglais, De proprietatibus rerum, XVI. 31; Vincent de Beauvais, Speculum naturale VIII. 62-63; Albert le Grand, De mineralibus, Lib.II, tract.2, cap.3; Jean de San Gimignano, Summa de Exemplis et rerum similitudinibus, II. 25 (rapport entre la pénitence et les propriétés de plusieurs pierres, parmi lesquelles le cristal). La littérature sur le sujet est vaste comme tu peux l'imaginer (Isabelle Draelants en a dressé une: http://medievistique.univ-lorraine.fr/contentId%3D9242), mais un bon point de départ reste le livre de Christel Meier, Gemma spiritalis (disponible désormais sur digi20). Quant à sa propriété de faciliter les naissances, je n'ai pas trouvé d'indice. Chercher peut-être du côté du De physicis ligaturis de Costa ben Luca (Qusta Ibn Luqa), du Liber aggregationis de Ps-Albert - je ne les ai pas sous la main (rien vu dans le De secretis mulierum, ni version salernitaine versifiée, ni version Ps-Albert; rien dans le Hortus sanitatis, qui reprend Albert le Grand et Vincent de Beauvais). Amitiés, Eduard ----- Mail original ----- De: "Marjorie Burghart" <[log in to unmask]> À: [log in to unmask] Envoyé: Mardi 10 Septembre 2013 00:55:22 Objet: [M-R] Properties of crystal? medieval-religion: Scholarly discussions of medieval religion and culture Dear list members, For a little speech I must deliver, I am trying to find the virtues attributed to crystal in the Middle Ages. I have read that it was thought to be petrified ice, and that it healed some sort of abdominal pains. But I have also found mentions, without clear reference, of crystal facilitating the delivery at childbirth. Would you know of medieval references for this virtue?
