This should really be the Well of Many Names or some such. The well itself is very attractive and much easier to identify than any of the other wells on Tara.
Just below the well is a spring or spout.
The well has undergone a major face lift. Access is now easy via a gate from the road and a nice fence encloses the area. I just hope they don't plant it up and make a 'feature' of it.
The names of this well are:
1) Caprach-Cormaic - Cormac's Well
2) Liagh - The Physician
3) Tipra-bo-finne - Well Of The White Cow
4) Deare-dubhe - The Dark Eye
This could also be the well called - "Poll tocair na tuiliche" which was used for trial by ordeal. The person under inquisition would enter the water and if guilty would emerge with a black spot upon their body; the innocent would come out of the water 'fairer then ever'.
This is an explanation of (and a bit of a disclaimer for) the coordinates I provide.
Where a GPS figure is given this is the master for all other coordinates. According to my Garmin these are quite accurate.
Where there is no GPS figure the 6 figure grid reference is master for the others. This may not be very accurate as it could have come from the OS maps and could have been read by eye. Consequently, all other cordinates are going to have inaccuracies.
The calculation of Longitude and Latitude uses an algorithm that is not 100% accurate. The long/lat figures are used as a basis for calculating the UTM & ITM coordinates. Consequently, UTM & ITM coordinates are slightly out.
UTM is a global coordinate system - Universal Transverse Mercator - that is at the core of the GPS system.
ITM is the new coordinate system - Irish Transverse Mercator - that is more accurate and more GPS friendly than the Irish Grid Reference system. This will be used on the next generation of Irish OS maps.
