How did the Greek philosopher Plutarch analyze the relationship between poetry and dance during the Roman Empire?

Plutarch believes that ugliness cannot be turned into beauty in art, but the realistic imitation of ugliness by art can also bring people aesthetic feeling. He talked about some aesthetic ideas related to dance. For example, he thinks: "The relationship between poetry and dance is closer than that between poetry and painting. The ancient Greeks sang the songs and dances of Apollo, the sun god, and Dionysus, the wine god, which was a combination of these two arts. Therefore, people can also move Jimenez's words from painting to dance, calling dance silent poetry, and poetry is a vocal dance. " His thoughts are of guiding significance to today's dance creation and performance.
