  "summary": "A working silversmith's textbook of geometry, proportion, anatomy and design, privileged by Philip II in 1585 after the manuscript burned and was written again. Its argument is that antiquity knew no difference between the sculptor, the architect and the silversmith, and that the first thing needed to work silver and gold is geometry. It was still being reprinted from the author's own plates in 1795, and the 1795 printer used the book to expose an earlier editor's false claim.",

This object goes to the text: the burnt manuscript and the twenty-year privilege granted because the book was \"conveniente para los Artífices y Plateros\"; the argument that antiquity drew no line between the sculptor and the silversmith; the six subjects a silversmith was told he needed, anatomy and sundial astronomy among them; the opening sentence that geometry comes first in working silver and gold. It then does what a reprint usually forbids and turns the edition into evidence — the 1795 printer restoring what a 1736 editor suppressed, and the royal mint's chief engraver's marginal note calling that editor's claim false. The last claim states plainly that the copy read is the reprint and that its history of itself is an interested one.",
