The stone is a spike of shale tall. On the west face is a cross with a V-shaped ornament beneath it, and on the east face is a Latin cross in a double circle and four concentric circles; this probably indicates a "pagan" monument that was later appropriated by Christians. Cloondacon is a townland in the Parish of Aughagower and Barony of Burrishoole in County Mayo. It is bordered to the northeast by Mace South, to the south by Tevinish East, to the southwest by Aughagower, to the west by Gorteen, and to the northwest by the Deerpark. Cloondacon is situated on Tochar Phádraig, the ancient route from Ballintubber Abbey through Aughagower to Croagh Patrick. The name Cluain Dá Chon refers to an ancient legend according to which a pagan chieftain set two wolfhounds on Saint Patrick. Instead of attacking Patrick, the hounds licked his hands. The chieftain was moved by this and became a Christian. According to an alternative version, St. Patrick made the sign of the cross over them, and the two hounds were swallowed up in an oval shaped hole called Poll na gCon (the hole of the hounds).
