The history of cartography is a fascinating journey that traces the evolution of map-making from ancient times to the present day. The earliest known maps date back to the Babylonians around 2500 BCE, where clay tablets depicted the surrounding regions and celestial bodies. These rudimentary representations were not merely artistic expressions; they served practical purposes, aiding in navigation and territorial claims. As civilisations advanced, so too did their cartographic techniques. The Greeks, particularly figures like Ptolemy in the 2nd century CE, made significant contributions by introducing a more systematic approach to mapping. Ptolemy’s work, “Geographia,” laid the groundwork for modern cartography by incorporating a grid system and latitude and longitude, which allowed for more accurate representations of the Earth’s surface. As the Middle Ages unfolded, cartography experienced a period of stagnation in Europe, largely due to the dominance of religious perspectives that viewed the world through a theological lens rather than a geographical one. However, during the Renaissance, a revival of interest in science and exploration sparked a new era for map-making. Explorers like Christopher Columbus and Vasco da Gama expanded the known world, prompting cartographers to create more detailed and accurate maps. The invention of the printing press in the 15th century further revolutionised cartography by making maps more accessible to the public. This period also saw the emergence of thematic maps that conveyed specific information, such as population density or trade routes, marking a significant shift in how maps were perceived and utilised. Summary Cartography has a rich history dating back to ancient civilizations, with maps evolving from simple drawings to sophisticated tools for navigation and exploration....
