Armillary spheres have become an icon of science with their elegant rings and beautiful silhouettes. Eratosthenes may have invented armillary spheres around 255 BC. These instruments are made up of a set of graduated rings representing circles on the celestial sphere, such as the meridian, equator, ecliptic horizon, tropics, and colures. With the aid of an armillary sphere, one can track the path of the sun for any given day of the year or determine a stars coordinates. The Earth is represented by the brass sphere located at the centre of the armillary sphere. This is a replica of a European Demonstrational Armillary Sphere. It was used to measure the relationships of the objects in the sky. It features a rich antique finish that does not tarnish or show fingerprints. Its a great addition to any nautical collection.

I found that based on the price, the description of the article & the quality of the craftsmanship, there was a significant difference of opinion and dis-satisfaction. I’m sorry to have to say this, but the item seems like an okay rendering.. Matthew. Brampton, ON. 2020-06-15 10:50:35
