This unusual map of 1685 illustrates ocean currents as understood at the time based on the observations of explorers and mariners. Though necessarily conjectural in many ways, it highlights the remarkable effort made by early cartographers to make sense of an accumulation of data from such reports without the visualisation tools we have today.
