Guillaume Delisle – World map, 1720

This is a world map created by Guillaume Delisle in 1720. The map is presented in a dual-hemispheric projection, showing both the Eastern and Western hemispheres side-by-side. It features detailed illustrations of continents, oceans, and islands, with names of various regions and bodies of water inscribed in French.

What I see:

• Dual-Hemispheric Projection: The map is divided into two large circular projections, representing the Eastern and Western hemispheres. This allows for a comprehensive view of the entire globe.
• Geographical Detail: Continents like North and South America, Europe, Africa, Asia, and Australia are depicted. Islands are scattered across the oceans, and major sea routes are partially indicated.
• Inscriptions in French: All labels, including continent names, oceans (MER DU NORD, MER DU SUD, MER PACIFIQUE, MER DES INDES), and place names, are written in French, reflecting the maps origin and intended audience.
• Cartographic Elements: Lines of latitude and longitude form a grid over the map, aiding in navigation and location.
• Decorative Embellishments: At the top, a cartouche features heraldic symbols (a crown and fleur-de-lis) and allegorical figures, signifying royal patronage and status. Banners with text are also present, identifying the maps creator and purpose. At the bottom center, an ornate cartouche contains publication details.
• Color Palette: The map uses a muted color palette, with landmasses outlined in black and colored in soft tones, while oceans are a pale green.

Subtexts:

• Royal Authority and Prestige: The prominent display of MAPPEMONDE à lusage du Roy (World Map for the Use of the King) and the royal crest (crown and fleur-de-lis) explicitly indicate that this map was commissioned or dedicated to the French monarch. This signifies the importance of cartography for royal administration, navigation, and asserting national power and knowledge.
• Guillaume Delisles Expertise: The inscription par Guillaume Delisle, Premier Geographe de SM (by Guillaume Delisle, First Geographer of His Majesty) highlights Delisles prominent position as a leading cartographer of his time. This inscription serves as a mark of his authority and the quality of his work.
• Age of Exploration and Colonialism: Maps of this era were not merely geographical tools but also reflections of expanding global knowledge and the ongoing process of exploration and colonization. The depiction of Terres Australes (Southern Lands), for example, reflects the European understanding and exploration of the southern polar regions. The naming and detailing of various regions also implicitly reveal European perspectives on ownership and dominion.
• Scientific Advancement: Delisle was a cartographer known for his scientific approach. The precision of his maps, based on the latest geographical knowledge and astronomical observations, represented an advancement in cartographic accuracy for the period. The grid of latitude and longitude further underscores this scientific underpinnings.
• French Dominance in Cartography: The creation of such a detailed and elaborate map at this time also speaks to Frances position as a major European power with significant interests in global exploration, trade, and military strategy, all of which relied heavily on accurate cartographic representation.
