Derreengreanagh Standing Stone: Luni-solar rises

East centred view with luni-solar trajectories c.1200BCE from Derreengreanagh Standing Stone, Cork, Ireland. As from the nearby stone group, equinox and summer cross-quarters are in prominent dips but the position of the equinoctial solar disc has shifted by about a semi-diameter. Again the equinox / summer cross-quarter midpoint is at a break and the equinox / winter cross-quarter midpoint is at another.
