Achates is a kinde of Gemme, but black in colour, enterlined here & there with white vaines: and it is called Achates of a certaine flood of that name in Cicilie, about the which floud this Achates was first found. There is a certain kind hereof scene somtimes in Crete as Diascorides witnesseth, having strokes on eche side like to blew vaines. There is another kinde in Indie bespotted on everie parte with spottes like bloud. That of Crete is said to make a man gracious, and bring him in favour. That of Indie is good for the eiesight it remedieth venome, and being put into the fire is odoriferus.
