Derreenataggart Stone Circle: Luni-solar sets

West centred view with luni-solar trajectories c.1200BCE from Derreenataggart West Multiple Stone Circle, Cork, Ireland. A long hill to the west is largely obscured but the equinox is at the basal break of the northern summit which is a quarter-month further while the southern top is a half-month further south. The half-month north of the equinox is axially indicated [Pic]. Equinox / cross-quarter mid­points are at near / distant intersects.
