This is the first fresco in the series of 3 Botticelli
painted for Pope Sixtus IV for the Sistine Chapel. It is
directly opposite the 3rd frescoe, the Temptation of Christ
and itself deals with the theme of temptation.
Reading the painting from right to left it depicts Moses
in a shining yellow garment striking an Egyptian overseer,
his flight to the Midianites, the dispersal of shepherds who
were preventing the daughters of Jethro form drawing water
at the well. Following the devine revelation in the burning
bush (top left) Moses leads the people of Israel in
procession from
slavery.
