About this work

Overview

Cornelis Galle II produced this copper‑plate engraving in 1647 as a title page for the mathematical treatise *Opus Geometricum Quadraturae Circuli* by G. de St. Vincent. Executed on laid paper as a proof before the addition of textual elements, the print measures roughly a sheet of modest size and functions as a decorative frontispiece for the work on circle squaring.

Subject & Meaning

At the composition’s centre stands a winged female figure clutching a shield and a globe, poised upon a pedestal. She is surrounded by cherubic putti and robed scholars, some gesturing or kneeling, while a radiant sun casts beams across a sky that includes distant architecture and a ship. The assemblage operates as an allegorical celebration of knowledge, geometry and the celestial order.

Technique & Style

Galle employed the fine line work and cross‑hatching typical of mid‑seventeenth‑century Flemish engraving to model volume and light. The careful modulation of ink creates a sense of depth, especially in the drapery and architectural background, while the crisp outlines delineate the numerous figures, reflecting the period’s emphasis on clarity and decorative richness in printed frontispieces.

History & Provenance

The print was created as a preliminary proof, intended to be printed before the title text and other typographic elements were added. It remained in the original binding of early editions of de St. Vincent’s treatise, and later examples have appeared in collections of scientific literature and in the archives of the Galle family’s print workshop.

Context

During the 1640s, the intersection of scientific inquiry and visual culture was common in the Low Countries, where engravers supplied elaborate title pages for scholarly works. Galle’s collaboration with de St. Vincent reflects this trend, pairing mathematical content with a visual allegory that would have appealed to patrons interested in both learning and decorative art.
