Actually, my idea is that archaeoastronomy is no more than a useful tool, or component, for a wider-view discipline, now in fashion, called Archaeology of Landscape. Regarding ancient Egypt, this connection has been shown in ShaltoutM.BelmonteJ. A., ‘On the orientation of ancient Egyptian temples: (1) Upper Egypt and Lower Nubia’, Journal for the history of astronomy, xxxvi (2005), 273–98.

It is interesting that the hieroglyphic name of the ancient Egyptian province which had Latopolis as capital was represented by a bull's foreleg. From Giza (or from Memphis, the ancient capital), Latopolis and its region are located to the north, where the constellation of Meskhetyu (The Bull's Foreleg) was clearly visible in the sky every night. Was the foreleg a synonym of north just as septentrional (from the Latin septem triones or seven oxen) or arctic (from the Greek arktos or bear) are synonymous with ‘northern’, all these terms being related to different names of the same constellation (or parts of it), the Big Bear?.
