Note 824 — STEEL.
William Johnston translation
Some account of this artist is given in J. C. Bulengeri de Pictura, lib. ii. cap. 7, in Gronovii Thesaurus Antiq. Græc. ix. p. 875. On the other hand, Sturm says, in that part of the Ritterplatzes which relates to architecture, p. 18: “An archduke at Florence discovered again the art of working porphyry, but suffered it to die with him in the year 1556.”
