Pannels with hemicycles in Northumberland (UK)
The hemicycle (or horse-shoe) seems to be present, at different levels, in prehistoric carvings, buildings and landscapes.

The hemicycle in the landscape is, like the bends of the rivers/serpents, often connected with important ritual prehistoric sites.
