Lessing is not the first person to question the homogeneity of poetry and painting, because the original text says that "laocoon by German scholar Lessing in the18th century is the first important work in the theoretical literature of modern poetry and painting", which shows that poetry and painting are not of a nature, but come from reading laocoon.

Lessing is a German dramatist, literary critic and aesthetician. By analyzing the difference between classical sculpture and poetry, laocoon demonstrated the boundary between plastic arts and poetry, that is, the boundary between space art and time art, and concluded that painting is more suitable for expressing beauty.
