About this work
Overview
Created in 1737 by English naturalist Mark Catesby, this print portrays a loggerhead turtle gliding on water. Rendered on laid paper, the image combines etched lines with hand-applied color, emphasizing the animal’s textured shell and the rippling surface beneath. The composition includes a fragment of driftwood, adding a subtle reference to the turtle’s aquatic habitat.
Subject & Meaning
The work focuses on the loggerhead turtle, highlighting the creature’s distinctive carapace pattern through fine linear detailing of each scute. The turtle’s slightly turned head conveys a sense of calm observation, inviting viewers to consider the species within its natural environment and reflecting Catesby’s intent to document New World fauna with scientific precision.
Technique & Style
Employing a combination of etching and engraving, Catesby incised the image onto a copper plate before transferring it to paper. Hand coloring was then applied to enhance the natural hues of the shell and water. The careful shading and line work create a three‑dimensional illusion, while the laid paper’s texture adds depth to the overall presentation.
History & Provenance
This series comprised 220 illustrated plates, each documenting a different species encountered during Catesby’s explorations of the American southeast.
The turtle print appears in Catesby’s multi‑volume work *Natural History of Carolina, Florida and the Bahama Islands*, issued between 1729 and 1747. This series comprised 220 illustrated plates, each documenting a different species encountered during Catesby’s explorations of the American southeast. The print has remained associated with the original publication, serving as a primary visual record of early American natural history.
Context
Catesby’s illustrations were among the first systematic visual records of North American wildlife, produced at a time when European scientific interest in the New World was expanding. By combining artistic skill with empirical observation, his prints provided valuable reference material for scholars and collectors, influencing subsequent naturalists and contributing to the development of modern zoological illustration.
