Since the sky appears to rotate around you in 24 hours, anything on the celestial equator takes 12 hours to go from exact east to exact west.
The above quote aligns with my way of thinking on this. It seems to me that even though the sun is still above the horizon after it travels nort

re a gradual
darkening for such a lengthy eclipse. And, the moon would travel very
slowly or be huge so watching it begin to eclipse the sun would not be
a matter of a few hours.

So my opinion is that it was intended to be vertically mounted at a mid to tropic latitude. (Depends on the measurement of the gnomon's angle.) It would have been useful on a porch or in a garden, facing directly south in the northern hemisphere at about 25 degrees latitude.

I have a question for those on this list with more experience (just about anyone!):
What would happen if a mirror were used not to reflect the sun's image, but as the dial itself?

I thank you for the information, and for the sources of information.
I've never waited more than one night for the Sun to return, so I can't imagine the feeling watching the sunrise for the first time in days, weeks or months!

It would actually take less than 10 years to observe and mark the complete cycle of the moon's travels, if a person started at the proper time. It would take less than 20 total years at most, if an observer were unlucky enough to start at the worst time in the cycle. For dedicated holy men who c
1) 18.6 year spirals: From reading various websites online concerning the Sun Daggers, it seems that the moon relation was never even considered until a photographer was developing a photo. He noticed two other marks--very faint-- that no one had noticed while viewing the petroglyph in person
In regards to the spiral representing 18.6 years (and not 18.5 or some other close number), I believe the answer is that the observations are directly tied to the 18.6 year cycle. So, if the observations were properly recorded, the spiral would indeed represent 18.6 years.

The 48 minutes that I also have seen online quite a bit should probably be 49 minutes. It can be calculated with the formula (Hours x Minutes / lunar month) to get (60 x 24) / 29.5. This gives 48.8. Many online examples use 30 for the synodic month. It actually takes the Moon 29.53 days to r
es will occur in the next six months to a year. It also is primarily intended as an online starting place for myself, no matter where I am. So don't judge too harshly!
