The ancient Slavs were pagans. They believed in animated nature and worshiped the Earth and Heaven, the Sun and the Wind, rivers and forests. The Slavs understood quite early that the main source of life on earth is the sun, which gives light and warmth. Therefore, when the gods appeared in them, among them there were immediately three incarnations of the sun.

Horse was considered the embodiment of the sun as a star. He was a deity of yellow sunlight. On his behalf, such words as "good", "round dance", "mansions" occurred. The word "horo" denoted a solar disk or circle. From him came the name of the dance, based on the movement in a circle, and circular buildings. Horse did not appear in heaven alone, he was always in the company of other gods. Since the sun cannot exist without daylight, Horse could not do without Dazhdbog.

Dazhdbog is the god of white light, the bearer of blessed solar heat. It was believed that he was traveling through the skies in a chariot in which four white winged horses with golden manes were harnessed. Dazhdbog constantly carries a fire shield with him, from which sunlight comes. At dawn and at sunset, this sunny god crosses the Ocean-Sea on a wonderful boat harnessed by geese, ducks and swans. A constant boar of Dazhdbog was a wild boar - a wild boar, and his sacred bird - a rooster, with his cry, informing people about the sunrise in the sun, i.e. about the approach of a deity.

Since time immemorial, the cross has been considered the sacred sign of the sun. The Solar Cross was often placed in a circle, and sometimes depicted rolling as a wheel of a solar chariot. This rolling cross is called the "swastika". The wheel could move on the sun ("salting") or against the sun ("salting"), depending on whether it depicted a "day" or "night" star. Unfortunately, the Nazis used the swastika in their symbolism, and now it causes rejection in most people.

The third solar deity in Slavic mythology is Yarilo. He was revered as the god of spring, the embodiment of her fruitful powers. Depended on him for her timely arrival. In addition, Yarilo was a cheerful and reckless god of spring passion. He was represented by an unusually handsome young man who, dressed in white clothes, rode a snow-white horse. Yarila has a flowery wreath on light brown curls, rye ears in her left hand, and a symbol of a human head in her right hand. When Yarila gets off the horse and steps barefoot through the fields, flowers bloom all around and golden rye rises.

The image of the Yarila-sun is present in the spring tale of Alexander Nikolayevich Ostrovsky "The Snow Maiden", based on Slavic mythology. There he appears to be a fair, but rather cruel deity, demanding a human sacrifice, which becomes the beauty Snegurochka melted in his rays.
