Rare separately published double hemisphere celestial map, first published in Amsterdam by Frederick De Wit in 1680, and here reissued by Covens & Mortier in 1721.
An exceptionally decorative, oversized, very rare celestial chart, produced by Frederik de Wit illustrating the two hemispheres surrounded by six supplementary models, illustrating the Copernican hypothesis, the Ptolemaic hypothesis, the Tycho Brahe hypothesis, the phases of the moon relative to the Sun, the rotational pattern of the day, and the rotation pattern of the Moon around the Earth.
Each major hemisphere is centered on the ecliptic pole and rendered on a polar stereographic projection with an external orientation. The constellations are drawn and colored to emphasize the signs of the Zodiac and other famous constellations.
De Wit's illustration of the constellations is clearly derived from the celestial hemispheres appearing as supplementary material on Joan Blaeu's 1658 wall map of the world (Shirley 371).
This is the second of two states. The plate was originally composed by De Wit. This is the Covens & Mortier issue.
