On the Universe

An engraving depicts the French polymath Guillaume Postel. He appears as an elderly man with a long, grey beard, wearing a scholar's cap and a robe featuring a large cross on the chest. He leans his right hand on a table covered with a fringed cloth, while his left hand holds a pair of dividers. On the table stands a thick book. The background features a shelf holding two armillary spheres, and in the foreground, a large globe sits on a wooden stand. The scene depicts the subject in a scholarly environment associated with cartography and astronomy.
