Nautical chart plotter

Mathematics

1570-1699

Nautical chart plotter, maker unknown, Italy, 1570-1699. The square of the plotter is marked with the names of the eight traditional winds of the Mediterranean, as follows: [TRAM]ONTANA (North – partially obscured in the photos by the arm of the plotter) GRECO (North-east) LEVANTE (East) SIROCCO (South-east) OSTRO (South) AFRICO (South-west) PONENTE (West) MAESTRO (North-west) The name of the South-west wind preserves the classical name (AFRICO), in place of the more modern equivalent Libeccio (“Libyan”). The arm of the plotter is marked with four linear scales for measuring distances on a nautical chart along a chosen bearing. The provision of four different scales allows distances to be measured more conveniently on charts of different scale. There is no interaction in use between the scales marked on the arm and the angles marked on the square.
