Author presents the astronomy side of astro-archaelogy very well. Reader is advised to have firm understanding of solar and moon mechanics. The author gives considerable details regarding origin and cultural history of Stonehenge and other sarcens. Different historians are quoted throughout book and examined in context of present archaelogy. Debate still exists over ceremonial/religious usage of Stonehenge. Author presents past ideas of a Mycenaean influence, pre-Roman conquest, and Egyptian influence.

Very enjoyable overview of archaeo-astronomy. Brown neatly debunks the lunatic fringe, reveals some of the unsung heroes of the field, and provides a clear summary of current ideas for the lay person.
