Focus on this artwork and discuss the The modern staircase.
The modern double helix staircase, also in the Pio-Clementine Museum, and commonly referred to as the "Bramante Staircase", was designed by Giuseppe Momo, sculpted by Antonio Maraini and realized by the Ferdinando Marinelli Artistic Foundry in 1932 and was inspired by the original Bramante Staircase.
This staircase, like the original, is a double helix, having two staircases allowing people to ascend without meeting people descending; as with the original, the main purpose of this design is to allow uninterrupted traffic in each direction. 
It encircles the outer wall of a stairwell approximately fifteen meters wide and with a clear space at the centre. The balustrade around the ramp is of ornately worked metal. 
A canopy located above provides the necessary light to illuminate the stairs. 
The staircase is located at the end of the museum visit and all visitors leave by this route.Several architecture professors have speculated that Momo’s staircase (particularly the skylight and atrium, and the helical nature of the ramp and the technical aspects of its construction) was the inspiration for Frank Lloyd Wright’s design for the Solomon R. Guggenheim Museum in New York.
