I have just uploaded
to our Ancient Ireland files.
The representation of Gemini and Auriga on the Clonkeen Stone are similar to the image found for this portion of the heavens at the world map on the channel stone at Monte Lungo, Sardinia.
Gemini in the county system is Offaly whereas Laois is Auriga.
We have a good etymological match of LAOIS as Auriga in the so-called barbarian ALIOC for Auriga (see p. 85 of Hinckley's Star Names).
OFFALY is in Gaelic Uabh Failghe (viz. Ui Failghe) = Gemini where Uabh is like Latvian ABI "two, both".
There is also a match to Anglo-Norman Frere for Gemini, which is Gaelic VRAAR "brother(s)".
Lastly, Ovid wrote Oebalii for Gemini so that OEBALII = OFFALY.
