For human in all ages, the Sun was more than a mere celestial body. It was a deity and source of life. However, one may see this deity only at the hours of its emergence on the horizon during the sunrise and the sunset. How did the people in ancient times observe, for instance, an incredible phenomenon of eclipse with their eyes safe? One might pour water into a bowl and watch the reflection. That was the very thing that they did for thousands of years, until the representatives of the Catacomb Archeological Culture improved the method.
