The practical pocket sea atlas by Marseilles hydrographer Joseph Roux, charting the ports and harbours of the Mediterranean, remained popular half a century after its first appearance in 1764. This edition, expanded to 163 charts, was published by a French bookseller in Napoleon’s short-lived client state, the Ligurian Republic.
