A sea chart of the Indian Ocean. There are two title cartouches, one in Dutch and one in French. Although the coastal outlines are very detailed, the main focus is on the islands of the Indian Ocean: the Seychelles, the Maldives, Sri Lanka and the Andaman Islands. The Maldives are shown as an overly large chain of islands, highlighting their importance in local trade. The Maldives were a source of cowrie shells and coir, a fibre made from dried coconut husk. Coir was used to make ropes as it was resistant to sea water, and was used for ships in the Indian Ocean.

The chart is taken from the second volume of Mortier's maritime atlas, the "Neptune Francois", which covered non-European waters. Mortier based many of the charts on manuscript maps drawn by the French diplomat Nicolas Perron d'Ablancourt after Portuguese sources.
