They're the same size other times, too :)

This is the only one that's really a long-odds coincidence. So far the
empirical odds are 1/N, where N=total number of moons in the solar system ...
(it might be interesting to figure out if any of the others come close). One
could quibble with EXACTLY here, too, since the moon's orbital eccentricity
produces both full and annular eclipses.

Already explained, tidal lock. Oh, and it's not exact, either, the moon
wobbles.

The caduceus in its modern form looks somewhat like a double helix (it's
usually tapered, though). The archaic depictions of it do not generally have
the serpents so neatly coiled; most of the time they are just in a rough
figure 8. The coincidence with the ida and pingala of Kundalini yoga is at
least as striking.
The arts and ritual of the ancient world were full of spiral forms in general.
Oh, and the CLOSEST coincidence to the form of the intertwined serpents is ...
*** Snakes mating ***
Well, OK, that involves DNA too :-)

Of course it matches the tides; the moon's gravitational field is the
main driver of tides.

Actually, lunar calendars were common in ancient times, but they don't line
up with the seasons. The moon's mean period is NOT 28 days, it's slightly
over 29, and variable, so the fit is actually pretty bad. A lot of lunar
calendars have 12 months instead of 13.
Fun. Got more/better ones?
