A bridge across the Afon Mynach, near Aberystwyth, Wales.
The story goes that an old woman who had lost her cow saw it
on the opposite side of the chasm but did not know how to
reach it. The Evil One appeared to her in the shape of a monk
and promised to throw a bridge across if she would give him
the first living thing that passed over it.
The old lady agreed. The bridge was completed and the
crafty fiend begged her to try it but the old woman had observed
his cloven hoof and his knee bent backward. She took
a crust from her pocket and flung it across the ravine, bidding
her little dog go fetch it. The devil was outwitted, as he generally
is in such tales.
