Critical theory, by Lucy R. Lippard, focusing on "contemporary art and it's connection to prehistoric sites and symbols. ... From megalithic monuments such as Stonehenge to Richard Long's minimalism, from the earliest examples of cave drawings to Ana Mendieta's Cuban site art, from matriarchal fertility rituals of the ancient Celts to Judy Chicago's 'Dinner Party', Lippard shows a continuum in the forms, materials, symbols, and imagery that artists have employed for thousands of years." -- publisher's statement.
