The vertical grooves and squared-off walls are very characteristic of quarry faces where blocks of stone have been extracted. In Italy, where Fellini filmed much of Satyricon, these kinds of landscapes were common, especially in volcanic or tuff quarries. The stepped and striated look comes from systematic cutting rather than erosion. So it isn’t a mountain naturally shaped that way, but an artificial industrial cut in the rock that Fellini incorporated into his surreal, ancient world.
