"Ouroboros", taken on my hike in the Storr, Scotland is my favorite photograph.
On the left you see a rock formation called "The Old Man of Storr" and on the right a younger man conquering the weather that happened to be rather dramatic.

The clouds formed a circle-like pattern that reminded me of an ouroboros symbol. Ouroboros is an ancient symbol depicting a serpent or a dragon eating its own tail. The meaning of the symbol is eternal cyclic renewal or a cycle of life, death, and rebirth.
