The set of seven prints of the liberal arts was published by Hieronymus Cock in Antwerp in 1565. In that set the Geometria print is numbered “6” lower right, with the name of the publisher Cock on the spine of the book in the lower left corner. The offered plate is apparently from a later edition — either a later state or re-engraved sometime between the original 16th-century edition and the 18th century — numbered “5” lower left, without the publication credit for Cock.
Frans Floris I was one of the more prominent members of the Floris family, which produced many artists including his father and brother. Painter, draughtsman and etcher, Floris was one of the leading exponents of Romanism in Antwerp, and his history painting influenced a generation of Flemish artists. He was largely responsible for the introduction of studios organized in the Italian manner, with skilled assistants — a practice subsequently adopted by other Netherlandish artists, most notably Rubens.
Cornelis Cort was a Dutch painter and engraver. He was a student of Hieronymous Cock, then went to Venice and studied with Titian. After several years there, he went to Rome where he founded an engraving studio and made important engravings after Italian, Flemish, and German engravings. He also mentored other engravers.
