Smooth Guitarfish (Rhinobatus rhinobatus) – Original hand-colored engraving by Pierre Antoine Prêtre, Antique Print

A Quiet Hybrid of Ray and Shark

This original hand-colored engraving depicts the Smooth Guitarfish (Rhinobatus rhinobatus), a creature that appears to sit between categories — ray-like in its head and shoulders, shark-like in its tapering body and tail. Prêtre presents the subject in a single, uncluttered view, allowing the strange unity of its form to speak for itself.

The composition is almost minimalist: one figure suspended in open space, framed like a specimen in a cabinet drawer. The long, pointed snout and the broad pectoral disc create a silhouette that feels both ancient and modern, as if designed rather than evolved.

The engraving belongs to the Italian edition of the Dizionario di Scienze Naturali (Florence, Battelli press), a monumental publication in which Pierre Antoine Prêtre’s zoological subjects stand out for their refinement and display quality.

Visual and Aesthetic Analysis

The palette is deliberately restrained — warm sand and muted olive tones, gently deepening along the dorsal line. Fine stippling builds the surface texture with a soft, velvety effect, while the fins fall away into cooler grey-blue shadows, giving the body depth without heaviness.

The pose suggests motion held in suspension: the fish is angled as if gliding upward, its tail narrowing to a quiet point. This sense of poised movement, combined with the generous white field, gives the plate a calm, almost sculptural presence.

About the Subject

Guitarfishes were especially compelling to nineteenth-century naturalists because they disrupted tidy taxonomies. Neither fully ray nor fully shark, they became living evidence of nature’s continuity — forms that refused the neat divisions of the study table. In encyclopedic works, such subjects carried an additional cultural charge: they suited the era’s fascination with “intermediate” creatures, as if the sea preserved forgotten architectures of life. The Smooth Guitarfish thus reads not only as a zoological document, but as a portrait of classification itself — an object lesson in how the natural world resists simplification.

Condition Report

The engraving is in excellent antique condition, with clean margins and a fresh, well-preserved hand-coloured surface. Printed on original smooth wove paper (non-laid), consistent with Italian scientific editions of the period. No watermark has been observed. The impression is clear and the colour remains vibrant, with no visible losses.
