Within the circular earthwork, lying in a line north-west and south-east, are two small untrimmed Sarsens, while outside the earthwork stands yet another unworked Sarsen, already referred to as the "Hele Stone" or "Friar's Heel." The fact that these three Sarsens are unworked, while all the others show very marked traces of dressing and trimming, is one that should be remembered. These three stones occupy no haphazard position either. As already stated, the "Hele Stone" marks the rising of the sun on the Summer Solstice. The remaining two mark both its rising on the Winter Solstice, and its setting on the Summer Solstice. THE HELE STONE OR FRIAR'S HEEL This stone, as being the largest of this group of three, and such a conspicuous feature in the structure, demands something more than mere passing mention. It is a monolith of unwrought stone standing sixteen feet high. Such untrimmed stones are to be found all the world over in connection with religious rites. Even the Jews were not untainted with this early cult of stone worship. "Among the smooth stones of the valley is thy portion; they are thy lot; even to them hast thou poured a drink offering, hast thou offered a meat offering," writes Isaiah. In Christian times the custom continued. The Council of Tours as late as A.D. 657 categorically excluded from Christianity all worshippers of upright stones; while later, Canute forbade the barbarous worship of stones, trees, fountains, and heavenly bodies. At once, therefore, this huge unwrought monolith suggests religion, and probably one of the earliest, and most primitive forms of worship. And thus being obviously connected with non-Christian rites, it is not surprising to find that it has a "devil-legend" attaching to it. THE LEGEND OF THE FRIAR'S HEEL
