Lecture given in May 1997 by Commander Christopher Terrell, Head of the Department of Navigation at the National Maritime Museum at Greenwich until 1987, on the evolution of the sea chart from its origins to nowadays. In a long journey that began from the early thirteenth-century sea charts on vellum to reach the nineteenth-century sophisticated British hydrographical surveys, chart-making underwent a variety of phases ranging from the Mediterranean portolans to the great contribution of the French eighteenth-century school of organised hydrography.
