The Rock Painting monuments found on the territory of Mongolia date from the early Iron Age, and bring us the message of our ancestors who lived 5000-3000 years ago. The monuments allow us to read the ancient history of Mongolia. The capable depiction of horse and ox-drawn carts attract the attention of researchers even today. While the earliest Rock Paintings depict wild beasts and birds, later paintings show increasing artistic ability and people’s life to a greater extent alongside with beasts. These works illustrate hunting scenes, sowing crops, the domestication of animals, ox-cart carriages, and even the intimate relations of men and women.
