Lest anyone think that the stones of TUILYIES in Scotland or ARDRISTAN in Ireland do not represent the Pleiades as eels - Manx Gaellic calls an eel an ASTAN (like ARDRISTAN), we have another site in Carlow County which settles the issue dramatically.
The remarkable Aghade Capstone near TULLOW (recall the similar TUILYIES in Scotland) - is one of the most unique megaliths in Ireland - and represents a swarm of eels all striving for the middle of the stone.
We have to recall that the ancients saw the Pleiades as the creative product of the Phallic symbol at the bottom of Perseus, i.e. the jutting extension or phallus of the Milky Way at the point.
As Enrico Calzolari has informed me about the beliefs of e.g. Sardinia, the Pleiades were always affiliated in this manner with fertility.
People have been at a loss to describe this stone, thinking it was a spider or some other strange object, and yet, anyone who knows anything about eels, sees immediatley that these are eels. Put bluntly, the eels represent the sperm of creation. As in mankind so in the universe.
Beliefs such as this disappeared as established churches stamped them out as paganism, supplanting them with "holy ghosts". Is it an improvement? You decide.
The Irish word for eel is EASG so this is not likely AGHADE, but perhaps the Gaelic term GAD meaning "withe" or "rod" would account for the site name AGHADE.
