[43] King, Precious stones, p. 12.
Treatises on precious stones frequently find a place in sixteenth-century Herbals, and are often accompanied by very spirited woodcuts representing the working of precious stones and the process of adapting them to personal ornaments, together with designs of actual articles of jewellery in which they are set. Two of the finest books of the kind are—an Ortus Sanitatis (Strasburg, circa 1497), and a Kreuterbuch printed at Frankfort in 1536.
