In recent years, researchers have rediscovered the important cartographic collection of Élisée Reclus (1830Reclus ( -1905 and Charles Perron (1837Perron ( -1909, which contains more than 10,000 maps of all kinds from the sixteenth to the twentieth century, including several reproductions of early maps from Antiquity and the Middle Ages. This paper explores the contribution of these two geographers to the history of cartography as a critical discipline, analyzing the construction of the Reclus-Perron cartographic collection. Then, it looks at some examples of its social and political utilization at the beginning of the twentieth century, namely at the Cartographic Museum of Geneva (1907Geneva ( -1922. These materials provide an original social interpretation of the history of cartography as a critical discipline endowed of a social utility, as well as an opportunity to explore a different way of conceiving maps and geography, one which diverged from the uncritical hagiographies of geographical discoveries and cartographic accuracy which were typical of that time.

If we consider that now our planet houses more than 7 billion people, we can infer that Reclus' arguments were not mere ideology. This map anticipated the idea of the Paris "Great Globe"as a symbol of human brotherhood, which I analyze in the next chapter.
A cartographic collection and the third dimension of the worldTo understand the value of the cartographic collection of Reclus and Perron, we must first see it in its historical context, as well as in relation to the broader scientific production of these authors. As stated by Harley and Woodward, the word cartography 'is a neologism, coined by These works stood among the references for Perron in constructing the Cartographic Museum, and many of the exposed pieces, reproducing early maps, were drawn directly from these sources.
