Cresques Abraham of the cartographic school on Majorca drew the Atlas Catalan,
a world atlas. It was drawn in 1375 and it was the first time that a map used
a compass rose. Completely unfolded the atlas is 65cm high (2 feet) and
3m long (10 feet). It does not only contain maps with miscellaneous figures and
motives but also instructions for navigation, calendars and interpreting star
constellations. The French national library has an original of this atlas.
The central motive of the atlas' calendar wheel is the geocentric world of Ptolemy. In the center an astronomer with a quadrant and the four elements earth, water, air and fire. Further shown the orbits of the seven known celestial bodies moon, mercury, Venus, sun, mars, Saturn and Jupiter.
The next ring shows for each of the bodies a figure and text about positions and appearance of the bodies.
The following ring shows the 12 signs of the zodiac and a ring with the various moon phases.
