The Cubiculum of Jonah

Catacombs wall paintings

In the first image Jonah exits from the great fish. In the other one, he sleeps under the gourd tree in the nearer panel, in the same posture that we see in pagan sarcophagus images of Endymion and of the sleeping Ariadne. In the farther panel he is climbing a cliff. There are no cliffs in the story. Could the image refer to Jonah 4:5, "Then Jonas went out of the city, and sat toward the east side of the city"?
