West centred view with luni-solar trajectories c.1200BCE from Doolin Stepped Barrow & Standing Stone, Clare, Ireland. Summer cross-quarters are on top of the Arran Islands. Winter ones are over a ridge end and so is the equinox / winter cross-quarter midpoint. The equinox is over the left end of an island.
