Answer:  An ornate wavy line
An ornate wavy line separates the upper section from the lower region in the wall paintings.

The rows of horse rider deities represent the cosmography of the Rathvas. The uppermost section with riders represents the world of gods, heavenly bodies and mythical creatures. An ornate wavy line separates this section from the lower region, where the wedding procession of Pithoro is depicted with minor deities, kings, goddess of destiny, an archetypal farmer, domestic animals, and so on, which represent the earth.
