Stonehenge is a massive neolithic monument in the county of Wiltshire, England, consisting of large stone columns arranged in a circular pattern. Built by the ancient Britons around 2500 BC, the monument's original purpose has been lost to modern knowledge. Two theories of the reasons behind Stonehenge's construction suggest that it was built for religious and scientific purposes, respectively.
The Lapiths built Stonehenge on the Tin Isle. Cheiron the Centaur found the structure impressive in the extreme, even more so than the kings' tombs and massive statues of themselves which the Sphinxes built. Cheiron asked Geraint about its origins. He expected to hear that the mans had been ordered to build it by their gods. Instead Geraint informed Cheiron that they had built it to gain understanding of the physical universe through scientific inquiry, a concept which Cheiron had difficulty understanding because he had never encountered it in a mortal species before. This added to his belief in the inherent superiority of mans to other beings.
