This episode looks at the fascinating history of sea charts, a subject crucial to the making of the modern world. The world took shape in our minds through the development of the sea chart, which in turn led to colonization, globalisation - a great mixing of the populations of the world that has created our diverse nations and complex history of today. It is often assumed that ships alone were the tools by which the sea became arteries of trade transport and conquest, but that is to overlook the sea chart as the indispensable instrument that made this happen.
