Note 1591 — AURUM FULMINANS.
William Johnston translation
Kircheri Magnes. Coloniæ, 1643, 4to, p. 548. The author says that he found the receipt for preparing it in Liber insignis de incendio Vesuvii. That I might know whether this work contained anything respecting the history of aurum fulminans, I inquired after it. Kircher undoubtedly meant Incendio del Monte Vesuvio, di Pietro Castelli; in Roma 1632, 4to: but the directions given there, p. 46, for making oro fulminante, are taken from Crollius. Nothing further is to be found in Kircher’s Mundus Subterraneus.
