In existographies, Geoffroy Vallee (c.1545-c.1574) was an French anti-religion writer, characterized an “Epicurean deist” (Ѻ), discussed by Pierre Bayle (1697), who found unbelief in god in Ecclesiastes and the first psalm (Hecht, 2003), who burned at the stake for atheism or for not believing in god in 1571 or for heresy in 1574, depending. [1]

Overview
In c.1570, Vallee published Erre Geru: the Scourge of the Colorful Foy (Erre Geru, le fieau de la Foy bigarr'ee), which was full of blasphemies and impieties against Jesus Christ.

Valee claimed that believers were “like parrots” reciting the irrational views they had memorized before they left the cradle. He asserted that one should only believe that which could be learned by the senses and those ideas for which one could show rational proof. [1]
