This exceptional 718-gram bronze cabinet plaque was created by the renowned German medalist August Vogel (⁠A. VOGEL FEC.⁠) to commemorate the 200th anniversary of the Prussian Academy of Sciences (1700–1900). The obverse features a masterful Art Nouveau allegorical relief of the Fountain of Knowledge. The reverse, styled as a triptych under the Academy’s Latin motto "Cognata ad sidera tendit", pays tribute to Germany's greatest minds: the left wing honors 18th-century founders like Leibniz, Euler, and Frederick the Great, while the right wing lists 19th-century giants including the Grimm Brothers, Helmholtz, and Virchow. Rare large presentation format 19*16.5cm, historically reserved for institutional collections and high-ranking academics. The piece remains in excellent museum-grade condition, showcasing a magnificent, untouched olive-brown aged patina that fully guarantees its historical authenticity.
