Abstract<\/strong><\/p>\n\n\n\n This study is part of a more extensive research that\naims to examine in depth the geometrical-spatial origin of skew curves\nbelonging to conical surfaces of revolution: conical spiral and conical helix.\nThe study begins with an investigation concerning the geometrical tracing, and\nthe spatial origin of both the skew curves and the ruled surfaces they\ngenerate, carrying out a comparison of the different formal characteristics\nthrough a number of algorithms that control the reference properties, written\nwithin the renown Rhinoceros<\/em> plug-in,\nGrasshopper.<\/em> Then follows an in-depth\nanalysis of an admirable example of architecture dating back to the first\nthirty years of the past century and made by the Architect Engineer Giuseppe\nMomo: the double-ramp helicoidal stair, located at the entrance of the Vatican\nMuseums in Rome (1929-1932). According to project designs found in literature,\nand through innovative graphical analyses, the geometrical-formal system of the\nwork object of study is here illustrated. <\/p>\n\n\n\n The study deepens the geometric-spatial genesis of a wonderful example of conical helical staircase at the entrance of the Vatican Museums. The Momo architect determines genial technical solutions, ensuring the security and comfort along the staircase and emphasizing at the same time the development of the spiral slab.<\/p>\n\n\n\n References<\/p>\n\n\n\n [1] CORAZZOL S.\n(2008).
