MERCATI, Michele. Metallotheca. Opus posthumum, auctoritate, & munificentia Clementis undecimi ... Cui accessit appendix.
Roma, Giovanni Maria Salvioni, 1719
An extremely rare work, masterfully illustrated. Edition edited by Lancisi, second issue with the date 1719 on the title page and the addition of the important 'Appendix'. Honeyman: “Remarkable Work on the Vatican Mineral Collection”. A seminal treatise in the history of mineralogy and metallurgy, describing what was one of the first organized mineralogical museums ever established. Notable for its excellence of style and clarity, the Metallotheca is much more than a simple treatise on minerals and metals. It provided a uniform generic classification for all known minerals and fossils. It also introduced a "notevole discorso sulle variazioni della superficie e del sottosuolo terrestre causate da lunghe epoche di evoluzione geologica". The text is illustrated with 150 exquisite engravings of rocks, minerals, fossils, and corals, all rendered in admirable detail (the 20 included in the supplement are repeated or re-engraved). Since this is the Vatican mineralogical collection, Mercati included several marble statues from the Vatican collections, including the Belvedere Torso and the Laocoon.
Sinkankas: “The collection reflects the state of knowledge extant at that time and therefore includes objects of presumed magical or medicinal virtue as well as those which are correctly identified and described. The plates can scarcely be equalled for fidelity to originals and the exquisit care employed in their engraving and printing”.
The plates outside the text are: Frontispiece with the Pope enthroned receiving the book; Portrait of Mercati, between pp. xx-xxi; Allegorical title page after p. xlv; Folded view of the Museum; Portrait of Lancisi; Armarium ‘Terrae’, between pp. 6-7; Armarium ‘Sal et nitrum’, between pp. 24-25; Double-page view of the mines of Pozzuoli, after p. 78; a coral, after p. 100.
