The Son of the Sun

Some historians believe that acrobatic moves such as the cartwheel and somersaults were originally "invented" by the ancient Heathen priests who generally used the shape of the circle to imitate and worship the Sun. In the ancient past nobody would even think to use these moves to entertain the crowd, the acrobatic techniques were sacred and had purely ritualistic value. Such dangerous, death-defying acrobatics helped the shamans to communicate with the Sun by temporarily putting themselves in the dimension between life and death, the world that was believed to be the home of gods. Several thousand years later the moves lost their original magical value and transformed into a form of public entertainment...

About the drawing

Once a year, a chosen young man has to travel alone to the middle of the desert, where he would perform a very special dance for the Sun itself, and since it's a dance for the Source of All Life, it would have to be extremely well "polished" and the young man himself would have to be what the current era's people call "angelic" XD

So if the village's elders noticed an overly handsome boy, they might ask his parents to start training him for the dance, according to the ancient tradition. His mom would be responsible for the softness of the moves (aka choreography) and his dad for the softness of the body (aka "no pain no gain"), to make sure the boy is flexible enough to do all or most of the postures canonized in the ancient scrolls (though, some of them didn't look doable at all but were believed to have been achieved by some of the legendary dancers).

After the young man arrived to the desert, he'd change his clothes to a soft silky outfit, never worn before, and please the Sun's eye with the shapes as round as the human body can get... if succeeded, the village would have a good harvest, healthy newborns and other bonuses :]
