Bruno’s Oxford disputations collapse into public conflict

In 1583 Bruno’s appearances at Oxford — lectures and disputations on cosmology and the doctors’ Aristotle — collapsed into insult and counter-insult, a public academic conflict he later staged in La cena de le ceneri. It is not the embassy household’s cohesion, not the 1584 book as print, and not the Roman pyre. He mocked; they shut. The row stores polarization of a university public. Castelnau’s table still fed him; Dee is not this disputation; 1600 is another court.

Context

Oxford in 1583 was not a Copernican seminar. A Nolan who called doctors pedants made a camp: town-and-gown against the Italian. Castelnau’s table still fed him after the insult. That is why household cohesion and Oxford polarisation can share a year without being twins. A quarrel that later literature made famous is still a 1583 room.

Shared responsibility is part of Bruno’s Oxford disputations collapse into public conflict. Naming Giordano Bruno does not delete co-authors, institutions, or later transmitters. The lag from 1583-06-01 to any measured indicator is not treated as zero. Alternative explanations — weather, other armies, later statutes, or independent cultural change — remain live where the sources do not close them.

Why it matters

Worsening polarization path: a university against a visitor. High confidence on 1583. Modest weight. Cena remains 1584 print. Embassy remains cohesion. 1600 remains another court.
