Tullycommon Bone
The Tullycommon Bone is an archaeological find, discovered in 1934 during excavations of the fortification of Cahercommaun in the townland of Tullycommon, County Clare, Ireland. It is a complete metacarpal bone of a sheep with an Ogham inscription on each side. The find dates from the 7th to the 10th century.
Inscription
The Tullycommon bone has a short Ogham inscription next to various decorative elements such as zigzag lines on each side.The characters are clearly Ogham characters. A fact that is also typical of Ogham inscription lines with those used start and stemlines whose tips go through the main line. In order to mark the beginning of one of the two inscriptions, instead of the arrow running to the right, as with the Buckquoy spindle-whorl, an X next to the stemline is used.
The signs for C and S are clearly recognizable as Ogham signs on one side of the bone. On the other side may also be recognized the sign for the sound sequence EA as well as the sign for M.
It is not possible to decipher the inscription. According to Macalister, "It makes no sense to decipher a short inscription of this kind...". If these are not doodles, the signs may actually have been used for magical purposes. Perhaps the bone was one of a whole series of bones used for fortune-telling.
