He attended south-German nobility and prelates, corresponded with Johannes Reuchlin, and stood among the notable physicians of Renaissance Ulm.\u003c\/p\u003e\n  \u003cp style=\"font-size:12px; letter-spacing:1.8px; text-transform:uppercase; margin-top:30px; margin-bottom:8px; color:#555;\"\u003eThe amalgam passage\u003c\/p\u003e\n  \u003cp style=\"font-size:17px; margin-top:0;\"\u003eThe work’s enduring importance is a single, remarkable passage, and it is present in this copy. The chapter itself declares the context before the recipe is reached: at p. 129, \u003cstrong\u003eCap. XIX — \u003cem\u003eDe Dolore Dentium, \u0026amp; Dentibus perforatis\u003c\/em\u003e\u003c\/strong\u003e (“On toothache, and on perforated teeth”). Four pages of remedies follow — hops in vinegar, oak leaves, colocynth after Mesue, ragwort root, garlic with frankincense, the \u003cem\u003eExperimentum Divi Imperatoris\u003c\/em\u003e — and then, at the foot of p. 132 under the rubric \u003cem\u003eAd dentes perforatos\u003c\/em\u003e, running over to p. 133:\u003c\/p\u003e\n  \u003cp style=\"font-size:16px; margin:18px 0 18px 0; padding:14px 18px; border-left:3px solid #c9bfae; background:#faf8f4;\"\u003e\u003cem\u003e“Fac canalem de auro fino, \u0026amp; per canalem cauterizetur dens cum alio auro usque ad mortificationem radicis dentis, postea imple foramen cum \u003cstrong\u003eAmalgama, facta ex Vitriolo, \u0026amp; Mercurio\u003c\/strong\u003e, ita ut sequitur. ℞ vitrioli, \u0026amp; dissolue cum aceto forti in patella, adde Mercurii quantumvis.

Then let it be boiled, and the mercury will be turned into an amalgam; and place that amalgam in the cavity of the tooth, \u003cstrong\u003eand it hardens like stone\u003c\/strong\u003e, and it serves for every cavity.”\u003c\/p\u003e\n  \u003cp style=\"font-size:17px;\"\u003eIt is not merely a filling material but a complete operative sequence — a gold cannula, cauterisation of the pulp through it, then the amalgam restoration — and it is \u003cstrong\u003ewhat scholarship records as the earliest known Western prescription for filling a tooth with amalgam\u003c\/strong\u003e. Since Stocker died in 1513, the prescription originates fully a century before the printed text offered here.\u003c\/p\u003e\n  \u003cp style=\"font-size:17px;\"\u003eToll’s apparatus is keyed to this very chapter. The printed note-letter \u003cem\u003ec\u003c\/em\u003e on p. 132 attaches to \u003cem\u003eLap. Magn.\u003c\/em\u003e — lodestone as an ingredient in the preceding mouthwash — and note \u003cem\u003ec\u003c\/em\u003e on p. 133 opens a long commentary on the magnet that runs to p. 137, marshalling Dioscorides, Pliny, Galen, Agricola, Boëtius de Boodt, Gesner, Cardano, Scaliger, Clusius, Cesalpinus, Camerarius and Paré, and citing at p. 137 \u003cem\u003e“Gilbertus quidam Anglus totum librum de magnete scripsit”\u003c\/em\u003e — William Gilbert’s \u003cem\u003eDe Magnete\u003c\/em\u003e — together with Fabricius Hildanus’s celebrated case of a steel splinter drawn from a peasant’s cornea by lodestone. A practical medical handbook engaging with the founding text of magnetism half a century after its publication.\u003c\/p\u003e\n  \u003cp style=\"font-size:17px;\"\u003eStocker was a physician of markedly rational cast: his pupil and successor Wolfgang Reichart records that when a peasant’s uncanny singing convinced villagers he was possessed — they stood ready to cart him off for exorcism — Stocker explained from medical philosophy that melancholics may utter prophecies and strange tongues through natural disease, not through any demon.\u003c\/p\u003e\n  \u003cp style=\"font-size:12px; letter-spacing:1.8px; text-transform:uppercase; margin-top:30px; margin-bottom:8px; color:#555;\"\u003eEdition and collation\u003c\/p\u003e\n  \u003cp style=\"font-size:17px;\"\u003eAlthough this copy lacks its title-leaf, the edition is fixed with confidence by its collation. The work appeared in three editions — Frankfurt 1609 (first; 236 pp., octavo), Leiden 1634 (second; small octavo), and Leiden 1657 (third; 361 pp., duodecimo). The present copy’s 361-page duodecimo collation matches the third edition of 1657 exactly (union-catalogue records, K10plus \/ VD17).\u003c\/p\u003e\n  \u003cp style=\"font-size:17px;\"\u003eWhat sets this edition apart is textual, not merely bibliographic. Stocker’s casebook first appeared in 1609 (Frankfurt) as the bare \u003cem\u003ePraxis morborum particularium\u003c\/em\u003e, printed from his posthumous papers; in 1634 the Leiden physician Adrian Toll (Adrianus Tollius, d. 1635) re-edited it, furnished it with running commentaries, and gave it the title it now bears — \u003cem\u003ePraxis Aurea\u003c\/em\u003e. The present 1657 is Toll’s recension in its final, enlarged-and-corrected state (“editio tertia, auctior et emendatior”) — the fullest form the text ever attained.\u003c\/p\u003e\n  \u003cp style=\"font-size:17px;\"\u003eIt is genuinely scarce. Across all three editions WorldCat locates the work in only some nineteen libraries worldwide; the 1657 third edition itself is recorded in the K10plus union catalogue in just three — the Staats- und Universitätsbibliothek Göttingen, the Herzogin Anna Amalia Bibliothek at Weimar, and the Marienbibliothek Halle (OCLC 831622215). It is uncommon in commerce as well: across Rare Book Hub’s archive of more than sixteen million auction records, Stocker’s \u003cem\u003ePraxis\u003c\/em\u003e surfaces only three times — Hodgson \u0026amp; Co. in 1960, the 1634 second edition at Catawiki in 2024, and once within a group lot at Bonhams in 2025 — none identifiable as the 1657 third edition, and none presently offered in the trade but modern print-on-demand reproductions.\u003c\/p\u003e\n  \u003cp style=\"font-size:12px; letter-spacing:1.8px; text-transform:uppercase; margin-top:30px; margin-bottom:8px; color:#555;\"\u003eLiterature\u003c\/p\u003e\n  \u003cp style=\"font-size:17px;\"\u003e\u003cem\u003eDeutsches Literatur-Lexikon.
