Crescent.

Waxing crescent

Waning crescent

May 8 is World Red Cross Red Crescent Day.

Because, as you can see, it was crescent shaped.

It retains its crescent shape and moves in the direction of the horns.

On the night of the crescent moon, the first part of the solstice, it will come.

And that crescent there is the moon Enceladus, which is about as big as the British Isles.

So basically, Baku is this sort of crescent bay overlooking the island of Zira, the island that we are planning almost like the diagram of their flag.

Well, to answer the slightly easier question first, about 10,000 years ago, I would say, is the beginning of this process in the ancient Near East, known as the Fertile Crescent.

If we add a crescent moon shape, and a circle with a line on it in front, the two lines now have a context, a relationship to their surroundings, and are magically revealed as the letter T.

I think all of us have been interested, at one time or another, in the romantic mysteries of all those societies that collapsed, such as the classic Maya in the Yucatan, the Easter Islanders, the Anasazi, Fertile Crescent society, Angor Wat, Great Zimbabwe and so on.

What happens is that the wind blows the sand up the shallow slope on the other side, and then, as each sand grain hits the top of the ridge, it cascades down on the inside of the crescent, and so the whole horn shaped dune moves.
