Gender terms have been used to interpret some aspects of the archaeology of Neolithic and Early Bronze Age monuments. Frequently male and female inhumations are aligned cardinally and standing stones may be ‘male’ pillar and ‘female’ lozenges. However, the astronomical alignments at monuments are frequently on lunar standstills and solstices which bisect the cardinal alignments. The anthropology of gender suggests that the concept of a ‘gender of power’ is useful in explaining how ritual power is realised through the scrambling of sexual identities. Proficiency in aligning monuments on lunar-solar cycles may well have been a device to appropriate ritual power.
