First Maps

Every map you have ever trusted began as an act of imagination.Before satellites, before printed atlases, before anyone had seen the Earth whole, people drew their world anyway — a Babylonian scribe centring the universe on his own city in wet clay, a Greek philosopher daring to draw the Earth as a circle, a Chinese official carving a coastline into stone so accurate it still impresses surveyors. They were not failing to make modern maps. They were answering different questions: Where is home? Who rules what? Which way do I sail, pray, march, or bury my dead?The First Maps tells the story of the world's first mapmakers in forty chapters — one map, tradition, maker, or idea at a time. Thomas Meridian follows the clay tablets of Mesopotamia, the measuring genius of Eratosthenes, Ptolemy's fateful grid, Rome's road-books, the grid masters of China, al-Idrisi's silver world made for a Norman king, the sermon-maps of medieval cathedrals, the suddenly accurate portolan sea charts, and the Pacific navigators who held their maps in sticks, shells, stars, and memory. Along the way it explains, in plain language, how scale, projection, and longitude were invented — and why the longitude problem defeated mapmakers for two thousand years.Inside you will discover:The Babylonian world map, the Nippur city plan, and Egypt's gold-mine papyrus — the oldest maps that surviveHow Eratosthenes measured the Earth's circumference with a shadow, and why Ptolemy's errors steered ColumbusChina's grid cartography, from Pei Xiu's six principles to a coastline carved in stone in 1136The Islamic atlas tradition — the Balkhi school, al-Idrisi, al-Biruni, and Piri Reis, told without the mythsMappaemundi, the Catalan Atlas, and Fra Mauro — maps as sermons, jewels, and interviews with sailorsStick charts and star compasses: the Pacific's maps that were never drawn on a pageThe Vinland Map forgery, Behaim's 1492 globe, and the 1507 map that named AmericaWho this book is forFor history readers, map lovers, museum wanderers, and anyone who has ever stood in front of an old map longer than they meant to. No prior knowledge is assumed — every term is explained as it appears, and contested evidence is flagged honestly rather than smoothed over.The first maps were wrong in fascinating ways — and right about the one thing that matters: a map is never just geography. It is a worldview, drawn.
