I thought this story featured at The Daily Grail (www.dailygrail.com) last week (Feb 25) was noteworthy:
The existance of a matching Sphinx on the opposite of the Nile would explain the later importance of the "Avenue of Sphinxes". Unfortunately, the story didn't generate much discussion at the Daily Grail. A pair of Sphinxes would seem to suggest a "gateway" into Egypt with the Sphinxes positioned as guardians of the Nile passageway. Probably there is some celestial parallel to this as well.
