This Italian commemorative stamp from 1942 honors Galileo Galilei’s tenure at the University of Padua (1592–1610), one of the most productive periods of his scientific life. Printed in a rich red-orange tone, it depicts Galileo lecturing to his students, framed in an ornate Baroque cartouche with the emblem of Poste Italiane overhead. Issued during the 300th anniversary of Galileo’s death, the design by Corrado Mezzana blends historical reverence with classical Italian artistic style. A popular piece among thematic collectors of science, astronomy, and Italian history, this stamp remains a fine example of Italy’s wartime commemorative issues.
