## What you would see

A tall vertical black-and-white broadside printed in black ink on aged cream paper. The composition is layered in three celestial and earthly tiers. At the top, amid dense clouds and putti, two allegorical chariots drawn by fantastical figures flank a central coat of arms held by angels beneath a curved Latin banner. Just below, in a break of clouds, a winged horse — Pegasus — gallops forward with outstretched wings, with a lion and a bear-like beast trotting beneath. Two more chariots with classically draped figures hover above a thick tree canopy. In the middle ground, a natural arch formed by receding trees creates deep perspective; around it six robed academic figures gesture solemnly, three standing and two kneeling beside a central seated figure holding a book. At the bottom, a large rectangular cartouche densely filled with small text titled «CONCLVSIONES PHYSICAE» is flanked by allegorical figures, cherubs and two standing saints holding scrolls. The linework is exceptionally fine and precise, with cross-hatching typical of etching and engraving, giving textures to foliage, drapery, clouds and fur.

## How to look at it

Start at the top crest and follow the descent through Pegasus to the tree arch that frames the central group. Notice the theatrical gestures of the robed figures and the small animals beneath the winged horse. Finish by reading the lower text block as an academic poster supported by allegories.

## Context

This work is titled The Large Thesis by Jacques Callot (French, 1592–1635), dated 1625, from France, made as an etching and engraving according to data from the Cleveland Museum of Art where it is held. It is classified as a Print. Such illustrated theses were monumental broadsides used in 17th-century European universities to announce public academic defenses, in this case in physics, combining dense text with elaborate allegory. Inscriptions at the top and on the tree arch refer to patrons from Lorraine. The source provides no further details about the student or the specific textual content. The style belongs to the early Baroque and to Callot's prolific printmaking career.

## Curious detail

Jacques Callot pioneered the use of hard varnish for etching, which allowed for exceptionally fine and durable lines and enabled him to crowd hundreds of tiny, expressive figures into a single sheet.

## Questions

- How does your reading shift when academic text is staged as a celestial spectacle?
- What connection do you see between Pegasus, the chariots and the idea of knowledge?
- Whom do you think this sheet aimed to impress: examiners, patrons or the general public?
