Shun arguments that waste time going nowhere. I had a quick look. The third week in Feb is usually a cold spell. Most often the last one before spring. It is possible that what you say is true but it seems to be a silly reason to build a temple. How would they have persuaded the tax payers?

Perhaps it was built in celebration of 1 kings special day, birthday, marriage or death perhaps but that is unlikely too. And why build a temple to figure solar declinations anyway? All you need is a callendar.

It is more likely to have provided lunar and stellar data for use in navigation and for religious ceremonies, etc.


Concerning the alignment of the Sphinx.

What about all the other ecclipses that occures during the time between when the idea for it was concieved until it was finally aligned on site?
