The 2009 Compass Rose Geocoin™ design comes from a mid 1600s Portuguese map of Brazil. It is made with translucent colors and multiple angles in the background. The names of each wind direction encircle the compass rose representing the cardinal and ordinal directions. You can interpret the direction names at the 5th Anniversary Compass Rose Geocoin™ page.
The backside image is an armillary sphere. Armillary spheres were developed a few hundred years before the birth of Christ, modified several times as new discoveries were made, and used until the late 1700s. Earlier models have the earth placed at the center of the universe, and then later models reflect the sun in the center of the universe. They were used for navigation, but not as effective as other methods. In addition, they also helped to understand the heavens. They were great at measuring distances in the heavens and tracking movements of planets, comets, and other objects. But notably related to our special coins, they were used extensively for training navigators. The armillary sphere design on this coin is from the same era of the compass rose used on the front side.
