The author states, "Although we do not know how the Mesolithic people explained them, in later prehistory they were named after Anu/Danu, the principle mother goddess in early Irish mythology (Danu was also worshipped on the Continent). In Medieval texts, the province of Munster (stretching away on all sides of the Paps of Anu), is described as particularly prosperous due to the bounty provided by Anu. Given their form, it seems likely that earlier people would also have made the association between these mountains and a female goddess. At some point in prehistory, cairns were built on both mountain tops, making them resemble breasts even more."
