Sinusoidal Projection
Oldest Equal-Area
One of the oldest projections still in use, appearing in atlases as early as 1570. Parallels are equally spaced horizontal lines; meridians curve as sine waves. Equal area is preserved exactly, but the shearing distortion at the edges gives continents a pinched, windswept look.
