Monogrammist G.A. with the Caltrop

Monogrammist G.A. with the Caltrop is the conventional designation for an unidentified printmaker and illustrator active during a focused period in the early 16th century, documented circa 1525 through 1530. The known artistic output of this individual, focused primarily on architectural theory and ornamental study, comprises specialized prints and book illustrations.

Records show that nine prints and six books representing the Monogrammist’s work are held in institutional collections, including the Metropolitan Museum of Art. The prints are highly detailed, academic studies of classical components essential to Renaissance design. These include measured drawings such as Doric Entablature, Corinthian Base, and Doric capital with measurements, indicating the artist’s contribution to the dissemination of architectural treatises during this era.

The focus on precise geometry and classical orders suggests the artist was deeply engaged with contemporary humanistic and scientific interests. The lasting art historical relevance of these documents is affirmed by their inclusion in major institutions. Today, many Monogrammist G.A. with the Caltrop prints are preserved as museum-quality images, and many works from this period have entered the public domain, offering widely accessible downloadable artwork for historical reference.
