Knowth, while less well known than Newgrange is possibly even more spectacular. The main cairn sits in the middle of a complex of 17 mounds, most of which are considerably smaller. It was a fortified grange in the medieval period. Knowth contains 25% of all neolithic art in Europe including 2 calendar stones, both of which show the cycles of the moon. As most of the art at these sites is abstract, we have few clues as to the thinking processes of these peoples apart from these important calendars. Clearly the moon was very important to them. Usually greater attention to the moon than the sun is associated with societies where the female element is strong as menstruation cycles are tied to the lunar cycle. Societies in which the sun is supreme tend toward male dominence. While it is not much to go on, this evidence is suggestive of a strong female role in their society.
