Rare booklet of Pierre Prévost (1751-1839), physicist and philosopher of Geneva, recognized in the field of science for his contribution to the theory of heat exchange (he explained Pictet's experiment by arguing that all bodies radiate heat, no matter how hot or cold they are). He was also a renowned Hellenist, who, among other things, contributed a translation of Euripides. Early on he held the chair of literature at the University of Geneva. In 1786 he became politically active and was a member of the Council of Two Hundred. In 1793 he was appointed to the Chair of Philosophy and General Physics at the University of Geneva, a position he held until 1823. In this booklet, MÉMOIRE SUR UNE APPARENCE DOUTEUSE DE MIRAGE, Prévost explains the scientific causes for visual appearances that seem real but are not (i.e. mirages). It is known that Prévost
himself suffered from mirages, which he considered a type of visual affectation.
