 On 10 September 1656, having twice mentioned Morin’s astrological revolution for the Queen, Des Noyers wrote of Morin’s astrology, and later, with a touch of battlefield humor, alluded to the dispute between Morin and Gassendi, 22 June 1659.

After embracing that code of honor, Morin claims that Copernicans, “devoid of natural light,” will recognize in Boulliau’s work a “worthless gush of unfounded logic” that forces him now to “descend into the arena a second time” to oppose a moving earth and to defend Tycho.
