PLATE XXXVIII
"Temple of the three Windows," Machu Picchu. Windows are not a frequent feature of Inca architecture, and when Bingham discovered at Machu Picchu the temple with three conspicuous windows, here shown, this discovery seemed to give added plausibility to the theory that Machu Picchu is indeed the Tampu-Tocco of the Incas.
