Read the full account
In 1584 Bruno published La cena de le ceneri in London, an Italian dialogue staging an Ash Wednesday supper debate on Copernicus, the earth’s motion, and a Nolan cosmology that already exceeded heliocentrism toward infinite worlds. It is not De l’infinito as a separate 1584 title stored nearby, not Oxford’s 1583 quarrel, and not the 1600 pyre. He wrote vernacular argument; a London shop manufactured. The row stores one educational dialogue. Copernicus is an influence, not a co-author and not the sole later charge.
Context
Elizabethan London, via the French embassy, let an Italian exile print what Italy would not. Education here is vernacular access to cosmology, not a claim that the Roman Inquisition later burned him only for Copernicus — the charges were a thicker theological bundle. Castelnau hosted; Sidney and Greville are related hearers. John Dee is a neighbouring English magus, not this colophon. Castelnau hosted; Copernicus is an influence, not a co-author and not the sole later charge; 1600 is another instrument.
Why it matters
Improving education path: vernacular cosmology. High confidence on 1584. Modest-to-medium weight because the book became a public argument, still not a university statute. Execution remains a later harm done to him on complex charges. Infinite-universe treatise is a neighbouring 1584 title.

He wrote the Ash Wednesday Supper in Italian. London printers issued it. Complex author in Castelnau’s orbit, not Copernicus and not a later scientist-martyr brand.

A vernacular cosmological dialogue made Copernican and Nolan arguments copyable to a non-Latin public, a modest education path. It is not a heliocentrism-only martyr file.

What the sources establish
A public-domain Ash Wednesday Supper is on Internet Archive. SEP independently dates the 1584 London Italian dialogues and warns against reducing Bruno to a Copernican martyr. Official/public carrier: https://archive.org/details/ashwednesdaysupp0000brun (opens in a new tab). Independent: https://plato.stanford.edu/entries/bruno/ (opens in a new tab). The records establish 1584 Cena. They do not establish that 1600 was heliocentrism-only. Infinito and Causa are neighbouring 1584 titles, not this supper; a missing Cena would change the row. A contradictory first-edition year would change the row.
Established: Bruno published La cena de le ceneri in London in 1584. Not established: that this book is the unique cause of 1600, or that he died solely for heliocentrism. A showing of no 1584 Cena would change the row.
Confidence is stated on the impact path, not hidden in adjectives. Cena is not the 1600 execution and not a claim he died solely for Copernicus. Mixed effects of Bruno publishes La cena de le ceneri in London are separate paths.
Later competitions, monuments, translations, UNESCO listings, museums, and adaptations are not converted into extra lifetime acts.
That reading is an impact-path choice, not a property stored on the Fact itself.
Shared responsibility is part of Bruno publishes La cena de le ceneri in London. Naming Giordano Bruno does not delete co-authors, institutions, or later transmitters. The lag from 1584-01-01 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.
