As to the kinds of stone actually employed in the building of Stonehenge, the whole of the outer circle and the four stones lying beyond that circle are undoubtedly “Sarsen” (which are the boulder stones left by the ice-sheet of the glacial period on the Wiltshire downs). There are, in the inner circle, four stones which have been called “horn-stone.” The remainder are “diabase,” commonly called “bluestones,” and similar are found in Wales, and in parts of Cumberland and Cornwall, the so-called Altar Stone being a kind of grey sandstone, not sarsen. The large outlying stone, known traditionally as the “Friar’s Heel,” from a legend that when the devil was busy erecting Stonehenge he made the observation that no one would ever know how it was done. This was overheard by a friar lurking near by, and he incautiously replied in the Wiltshire dialect, “That’s more than thee can tell,” and fled for his life; the devil, catching up an odd stone, flung it after the friar, and hit him on the heel. This stone is also named the “Pointer,” because from the middle of the Altar Stone the sun is seen at the summer solstice (21st of June) to rise immediately above it. The Hele Stone is the true name, “Hele” meaning “to hide,” from Heol or Haul of Geol or Jul, all names for the sun, which this stone seems to hide. From the Friar’s Heel it is about 66 yards to a low circular earthen boundary, enclosing the area within which Stonehenge stands. Just within the entrance to this earthen ring lies a large prostrate stone called the “Slaughter Stone,” supposed by some to have been used for the slaughter of victims about to be offered in sacrifice at the altar. The Slaughter Stone (at the end nearest to the Friar’s Heel) bears evidence of tool-marks, there being six small round cavities made in it by blows from a flint tool. On the margin of the earthen ring, one 55 yards on the left, the other 95 yards on the right of the entrance, are two small, unhewn stones. [Picture: Ground plan as presumed to have been originally.
