Berlin: 1782-85; Paris: 1785-97.
Engravings with original hand-coloring, some embellished with silver and gold
Bloch's ambitious work is the most notable of all books on ichtyology. Published in twelve volumes, each of the 432 hand-colored illustrations is identified in several languages. Many of the plates bear dedications to the patrons who paid to have a particular plate engraved and included in the collection.
Bloch made every effort to be comprehensive in this study, searching out species from "the four corners of the globe." He attributes his success in this undertaking to the help of many individuals, including the Emperor Frederick the Great, who ordered all of his regional finance departments to send Bloch "...all the types of fish of their provinces and to include instructive remarks." Bloch's introduction goes on to thank numerous individuals for the fish that they sent him from Denmark, England, Guinea, Surinam, New York, the Malabar coast in India, and other locations.
This monumental work reflects the growing interest in fishing as a leisure activity in the 18th century. But the lavishness and sheer magnitude of this work transcend mere trend to reveal an artist who was passionately involved with his subject matter. The silver and gold touches Bloch employed to mimic the reflective qualities of fish scales lend a dramatic sparkle to many of these impressive and richly colored images. Bloch's "Ichthyologie" is a highly important work, and one of the most engaging of all 18th-century natural history works.
