Struggling with pictures in the early Académie royale des sciences: The case of Giovanni Domenico Cassini's Grand Selenography (1679).

Abstract

In 1679, the astronomer Giovanni Domenico Cassini published a large print detailing the entire visible surface of the moon with unprecedented meticulousness. This Grand Selenography is undoubtedly one of the most spectacular pictures ever produced within the Académie royale des sciences. However, it has remained widely neglected by historians up to now. This study offers the first account of the making and early reception of the print. It argues that the Grand Selenography remains uncompleted because it failed to satisfy Cassini and his contemporaries. Furthermore, its history allows us to shed new light on the range of issues that scientific pictures might have raised during Louis XIV's reign.
