Read the full account
At dawn on 17 February 1600 Giordano Bruno was taken to Campo de’ Fiori, gagged, stripped, and burned alive after Clement VIII’s congregation had declared him an impenitent, pertinacious heretic and handed him to the secular arm. He is the person killed, not the officer who lit the fire. It is not a later monument on the same piazza, not Galileo 1633, and not a heliocentrism-only sentence. The court condemned; the city saw the smoke. The row stores humanitarian harm done to him. His contribution is that of the stubborn defendant, already stored in 1599, not that of an executioner. A gag, a stake, and chants are the same killing, not extra Facts; later statues are other authors.
Context
A burning is a body-harm. Humanitarian-access here is the destruction of a person after a religious trial on mixed articles — worlds, theology of Christ and Trinity, sacraments, magic, and more, in the documentary tradition — not a laboratory dispute about one sun. Bellarmine assembled propositions; he did not need to hold the torch to be a related Inquisition actor. Later Campo statues are other authors. Galileo’s file is another court. He is the killed defendant, not the executioner, and heliocentrism-only is refused as the whole story.
Later competitions, monuments, translations, UNESCO listings, museums, and adaptations are not converted into extra lifetime acts.
Why it matters
Worsening humanitarian path: public burning of a condemned teacher. High confidence. Medium-to-high weight at the scale of one killing, still not a war. He is not the executioner. 1599 refusal is his speech-act; 1592 is the arrest; 1584 books are knowledge-access. Later statues are other authors.
Confidence is stated on the impact path, not hidden in adjectives. 17 February 1600 is not a later statue and not a Copernicus-only legend. Mixed effects of Bruno is burned at Campo de’ Fiori as an obstinate heretic are separate paths.

What the sources establish
Roma Capitale’s public portal locates Campo de’ Fiori as the city’s civic stage. SEP independently dates 17 February 1600, the gag, and the burning, and rejects a heliocentrism-only legend. Official: https://www.comune.roma.it/ (opens in a new tab). Independent: https://plato.stanford.edu/entries/bruno/ (opens in a new tab). Catholic Encyclopedia and Britannica are further finding aids. The records establish the execution. They do not establish a unique later martyr-index as welfare science. Death in bed would change the row; a later statue is not this fire; heliocentrism-only is refused. A showing he died in prison unburned would change the row.
Established: Bruno was burned at Campo de’ Fiori on 17 February 1600 as an obstinate heretic after a complex theological process. Not established: that the sentence was heliocentrism-only, or that a later statue is this killing. A contradictory death in bed would change the row.
Shared responsibility is part of Bruno is burned at Campo de’ Fiori as an obstinate heretic. Naming Giordano Bruno does not delete co-authors, institutions, or later transmitters. The lag from 1600-02-17 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.
That reading is an impact-path choice, not a property stored on the Fact itself.
