Boa Island and the Caldragh Cemetery Stone Figures. Boa is named after Babdb, Celtic goddess of Battles and frequently found in the company of (or disguise as) a crow. The strange monument is often described as a "Janus", referring to the two-faced Roman god. The statue is more than likely pre-Christian. The much smaller statue , equally enigmatic was "imported" from nearby Lusty Beg island - fittingly named the "Lusty Man".
