Michelangelo's fresco "The Last Judgment" resides in one of the holiest places in the Christian world -- the Sistine Chapel at the Vatican. Now a researcher is claiming that Michelangelo's inspiration for some of the figures in the 16th century masterpiece came from a far less exalted realm -- the brothels and bathhouses of Renaissance-era Italy.As reported in Britain's the Guardian and Daily Telegraph, author Elena Lazzarini, a researcher from Pisa University, has published a study stating that Michelangelo was inspired by his frequent visits to gay brothels and Turkish baths.
