Chronology of projection development

1570: Cossin produces a world map based on the projection with verifiably sinusoidal meridians.
1606: Jodocus Hondius (Amsterdam) uses the projection for maps of Africa and South America, presumably leading to the name Mercator equal-area.
1650 (ca.): Nicolas Sanson d'Abbeville uses the projection extensively for maps of all continents.
1675 (ca.): John Flamsteed (England) uses the projection extensively in astronomical maps and praises its accuracy in correspondence with Isaac Newton.
