Rationale
Several reasons support the name sinusoidal:
- Alternatives attribute Sanson and/or Flamsteed, yet neither developed the projection.
- The originator is not known with certainty.
- The name is descriptive.
- The projection is so obvious as to render attribution meaningless.
- Modern texts surveyed preferred sinusoidal by a 1.25¹: 1² margin. As the 20th century progressed we see a strong shift toward sinusoidal. (Steers and Mainwaring did not commit to one name.)
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.
- ca. 1650: Nicolas Sanson d'Abbeville uses the projection extensively for maps of all continents.
- ca. 1675: John Flamsteed (England) uses the projection extensively in astronomical maps and praises its accuracy in correspondence with Isaac Newton.
