Of Iaspis. chap. 53.
IAspis is a precious stone, & is gréene like to Smaragdus: but it is more dim of coulour. And there be seuentéene kindes thereof, as Isidore saith. For Ias∣pis yt is greene, is called Gemma Pinna∣sin, and though the chiefe coulour thereof be gréene, yet it hath many other colours meddeled among. The vertue thereof de∣stroyeth feaners and dropsie in them that beare him chastlye: and helpeth in tra∣uailing of childe: and driueth awaye fantasies: and maketh a man sure in pe∣rill, and abateth heate within, and staun∣cheth bléeding and sweat, and withstan∣deth lecherye, and letteth conception, and stauncheth menstruall bloud and Emo∣roides, if it be in pouder, and tooke with milke, it helpeth and healeth olde Tor∣ches and viles, and cleanseth the eyen of foulenesse and filth: And sharpeth and comforteth the sight, and withstandeth witchcraft and inchauntments, and is more vertuous in siluer then in gold. In the head of an Adder that is called Aspis, is found a little stone that is called Ias∣pis: and men suppose that it is a stone of wonderfull vertue. And some men sup∣pose that it hath that name, as it were Aspis, and men suppose, that it hath as many vertues, as diuerse coulours and veines, as Dioscorides saith. And ye best Iaspis is found in the mountaines of Sci∣thia, & Griphons kéepe this stone, as they doe Smaragdus, as Isidore saith.
