In a sunlit gallery of the Museo Archeologico Nazionale in Italy, astronomer Brad Schaefer came face to face with an ancient statue known as the Farnese Atlas.

For centuries, the 7-foot marble figure of the mythological Atlas has bent in stoic agony with a sphere of the cosmos crushing his shoulders.

Carved on the sphere — one of only three celestial globes that have survived from Greco-Roman times — are figures representing 41 of the 48 constellations of classical antiquity, as well as the celestial equator, tropics and meridians.

Historians have long looked on the Atlas as a postcard from the past — interesting largely as astronomical art.

But as Schaefer approached, he began to notice subtle details in the arrangement of the constellations. It wasn't that anything was wrong with the statue. If anything, the positions of the constellations were too perfect to be mere decoration.<snip>
