Classifications
pseudocylindric
Graticule
Meridians: Elliptic curves.
Parallels: Equally spaced straight parallel lines, with spacing greater than earth’s reality. Perpendicular to the central meridian.
Poles: Points.
Symmetry: About the central meridian and the equator.
Distortion
Undistorted nowhere. Neither areal inflation nor angular deformation dominate.
Parameters
One enumeration to select which ratio to use for height to width: 3:4 as inferred, or measurements as given in Shirley’s The Mapping of the World.
Similar projections
Winkel II has similar parallel spacing and similar meridional curves, but its pole lines are longer.
Origin
Appears in the 1544 map by Sebastian Cabot.
