About this work
Overview
Created in 1860, this hand‑colored lithograph depicts a pair of birds resting on rocky outcrops beside water. The composition is set against a modest backdrop of reeds and a pale sky, emphasizing the tranquil natural scene. The work is attributed to the German illustrator Joseph Wolf, known for his detailed animal studies.
Subject & Meaning
The foreground bird displays a predominantly green plumage, a yellow underside, an orange bill, and red legs, while the smaller companion behind it combines gray‑green feathers with a vivid orange facial area. The juxtaposition of the two species highlights subtle variations in coloration and form, reflecting a 19th‑century fascination with the diversity of avian life.
Technique & Style
Executed as a lithograph, the image was first drawn with greasy ink on a flat stone, then chemically treated to retain the drawing while repelling water. After printing, the artist applied watercolor by hand to enhance the hues. The delicate palette and precise rendering align with Romantic-era naturalist illustration, which prized both scientific accuracy and aesthetic appeal.
History & Provenance
Joseph Wolf produced the print during a period when illustrated natural histories were in high demand across Europe. While specific ownership records are limited, the work has appeared in several 19th‑century catalogues of wildlife prints and is now held in museum collections that focus on scientific illustration and Romantic art.
