A Comedy by Bruno the Nolan

Academic of no Academy; known as "the Annoyed One."

Bruno often used the moniker "the Nolan" to signify his birthplace in Nola, near Naples. His self-description as an "Academic of no Academy" is a satirical strike against the rigid, dogmatic scholarly institutions of his time. "The Annoyed One" (il fastidito) reflects his characteristic impatience with social hypocrisy and academic pedantry.

original Latin: "In Tristitia hilaris: in Hilaritate tristis." This motto reflects the philosopher’s belief in the "coincidence of opposites"—the idea that every emotion or state contains its own contrary.

This is the mark of the printer Guillaume Julien. It usually depicted two hands joined in friendship (the "Sign of Friendship"), but is poorly preserved here.

original: "Appresso Guglelmo Giuliano." Julien was a prominent French bookseller and printer active in the late 16th century.
