Poems of ancient Greek kings
In Homer's time, ancient Greek poetry and music activities were always carried out together with dance, which was similar to the trinity structure of ancient China poetry, music and dance. Perhaps ancient human society experienced such a stage of development. In Homer's time, music and poetry were often combined together, and they were often combined with chorus. The word chorus was often the same concept as group dance. Group dancing is described in Homer's epic: "Young people dance happily in groups. They dance alone or with girls, at weddings, at grape harvest festivals, or just to vent their youthful vitality. "
