The whole length of “the Stones of Karnak,” as the temple is called, measures, if we include its sinuosities, eight miles. The width varies from 250 to 350 feet. The highest stones are as much as seventeen feet high, and from thirty to forty feet in circumference. Vacant spaces have unfortunately been cleared by ruthless spoliators for the erection of the adjacent villages of Ploermel and Karnak, and the boundary walls of the neighbouring fields. But what toil and time must have been originally expended on its construction, we may infer from the fact that it consisted of eleven rows of stones, about ten thousand in number, of which upwards of three hundred averaged from fifteen to seventeen feet in height, and from sixteen to twenty or thirty feet in girth; one stone even measuring the huge circumference of forty-two feet. A glance at any engraving of this famous antiquity will show that the course of the avenues is distinctly sinuous, and that it defines the figure of an enormous serpent undulating over the ground. Necessarily, however, the resemblance is more striking to one who views the original _in situ_. To such, the alternations of the high and low stones, regularly disposed, may seem to mark with sufficient accuracy “the swelling of the serpent’s muscles as he moves along,” though this seems rather a flight of imagination. But at all events the spectator will acknowledge the evidence of design which clearly appears in the construction of the avenues. The Dracontium contains ten regularly defined areas; one near the village of Karnak, which is shaped like a bell or horse-shoe; the other, towards the eastern extremity, which approaches the figure of a rude circle, and is in reality a parallelogram with rounded corners. The circle and the horse-shoe were both sacred figures in the Druidical religion, as may be seen in Stonehenge, where they are united, the outer circles enclosing inner horse-shoes. The connection between the latter symbol and the Celtic faith is not very clear, unless it be intended as a representation of the moon. It has been conjectured that from this symbol, whatever may have been its signification, arose the superstition--even not now wholly defunct--of nailing a horse-shoe over a door as a protection against evil spirits.
