Campanella dedicated his _Atheismus Triumphatus_ to Scioppius, calling him 'the dawn-star of our age.' Schoppe was also the first credible authority to warn Sarpi of the imminent peril he ran from Roman hired assassins, as I hope to relate in my chapter upon Sarpi's life.

This man's letter to his friend is the single trustworthy document which we possess regarding the last hours of Bruno.

Its inaccuracies on minor points may be held to corroborate his testimony.
Scioppius refers to Bruno's early heresies on Transubstantiation and the Virginity of Mary.

He alludes to the _Spaccio della Bestia Trionfante_, as though it had been a libel on the Pope.[118] [Footnote 118: 'Londinam perfectus, libellum istic edit de Bestia triumphante, h.e.de Papa.

quem vestri honoris causa bestiam appellare solent.'] He then enumerates Bruno's heterodox opinions, which had been recited in the public condemnation pronounced on the heresiarch.
