Those who consider that Stonehenge was a temple have certainly much better grounds for such a theory than it would be possible to establish in respect to Avebury. Indeed, looking at the ground plan above, there is something singularly templar in its arrangement. In the centre is a choir, in which a dignified service could be performed, and a stone lies now just in such a position as to entitle it to the appellation it generally receives of the altar stone. Unfortunately for this theory, however, it lies flush with the ground, and even if we assume that the surface has been raised round it, its thickness is not sufficient to entitle it to be so called, judging from any analogous example we know of elsewhere. Around the choir is what may fairly be considered the procession path; and if its walls had only been solid, and there were any indications that the building had ever been roofed, it would be difficult to prove that it was not erected as a temple, and for worship. As, however, it has no walls, and it is impossible to believe that it was ever intended to be roofed, all the arguments that apply to Avebury in this respect are equally applicable here, with this one in addition. Unless its builders were much more pachydermatous, or woolly, than their degenerate descendants, when they chose this very drafty and hypæthral style of architecture, they would certainly have selected a sheltered spot on the banks of the Avon close by, where, with trees and other devices, they might have provided some shelter from the inclemency of the weather. They never would have erected their temples on the highest and most exposed part of an open chalk down, where no shelter was possible, and no service could be performed except at irregular intervals, dependent on the weather throughout the year. As, however, it differs not only in plan but in construction--being hewn and having imposts--from all the rude stone circles we are acquainted with elsewhere, no theory will be quite satisfactory that does not account for this difference. My belief is, that this difference arises from the fact that alone of all the monuments we know of its class, it was erected leisurely and in time of peace by a prince retaining a considerable admixture of Roman blood in his veins. All, or most of the others, seem to be records of battles erected in haste by soldiers and unskilled workmen: but of this hereafter. Owing to its exceptional character, the usual analogies apply less directly to Stonehenge than to almost any other monument. [Illustration: 25. Tomb of Isidorus, at Khatoura.]
