The outstanding upright stone at Stonehenge is so called.
Geoffrey of Monmouth says the devil bought the stones of an old
woman in Ireland, wrapped them up in a wyth, and brought them to
Salisbury plain. Just before he got to Mount Ambre the wyth
broke, and one of the stones fell into the Avon, the rest were
carried to the plain. After the fiend had fixed them in the
ground, he cried out, “No man will ever find out how these
stones came here.” A friar replied, “That's more than thee canst
tell,” whereupon the foul fiend threw one of the stones at him
and struck him on the heel. The stone stuck in the ground, and
remains so to the present hour. Source: Dictionary of Phrase and
