Scaling down the Earth's history: Visual materials for popular education by Nérée Boubée (1806–1862).

Spatial and temporal scales are essential components of geological sciences; both are almost always imbricated in complex ways, challenging geoscientific knowledge among nonspecialists and students. The present paper focuses on the efforts made by the French naturalist Simon-Suzanne Nérée Boubée (1806–62) regarding popular education on geology. Though Boubée is poorly known nowadays, he experienced some prestige during his lifetime. He worked as an independent teacher, offering private as well as free public courses. Boubée, as a nineteenth-century science popularizer, repeatedly insisted on his disposition for "spreading science for all." He extensively published books and journals on geology, all aimed at popularizing geological scientific knowledge, considered to be of paramount relevance. This paper analyzes three visual examples extracted from his works: the Tableau Mnémonique des Terrains Primitifs, destiné au géologue voyageur, avec son explication (1831), the Tableau de l'État du Globe à ses différents âges (1832), and the Tableau figuratif de la structure minérale du globe, ou résumé synoptique du Cours de géognosie de M. N. Boubée (1839), supplemented with images from the travel guide Deux Promenades au Mont Doré (1834). Our goal is to understand Boubée's efforts to synthesize information, scaling down geologic time and space into foldable materials that made geological knowledge cognitively and materially accessible to laypeople.
