The Devil’s Arrows

In Burl’s 1991 Yorkshire Archaeological Journal paper on the Arrows, he speculates on the fate of the fourth stone
“Exactly what happened to that stone is not certain but it is probable that in the early 17th century it was dragged to St. Helena, Boroughbridge, for the foundation of a bridge over the River Tutt”.
In the same paper Burl states that “the Devil’s Arrows possesses the features of a classical stone row:
1. it leads uphill from water;
2. it has a blocking or terminal stone at it’s lower end;
3. the stones of the row are graded in height with the tallest at the head of the gradient near a stretch of level ground;
4 The row has an apparent alignment on the most southerly midsummer rising moon”.
