D. Marcus Elieser Bloch's, ausübenden Arztes zu Berlin, Oeconomische Naturgeschichte der Fische Deutschlands, Berlin, Auf Kosten des Verfassers und in Commission bei dem Buchhändler Hr. Hesse, 1782-1795., A striking illustration of a fish, characterized by its vibrant colors and intricate detailing. The fish features a streamlined body with a blend of reddish and silvery hues, accentuated by prominent scales and elongated fins. Its large eye, framed by a golden ring, adds a focal point to the composition. Delicate line work showcases the textures of the fins and body, while subtle shading provides depth. In the upper left corner, a blank oval suggests a space for further identification or annotation, indicating the fish's scientific classification or common name. The overall composition highlights both the beauty and anatomical features of this aquatic creature.
