The place assigned by all the chroniclers as the location of the traditional Tampu-tocco, as has been said, is Paccaritampu, about nine miles southwest of Cuzco. Paccaritampu has some interesting ruins and caves, but careful examination shows that while there are more than three openings to its caves, there are no windows in its buildings. The buildings of Machu Picchu, on the other hand, have far more windows than any other important ruin in Peru. The climate of Paccaritampu, like that of most places in the highlands, is too severe to invite or encourage the use of windows. The climate of Machu Picchu is mild, consequently the use of windows was natural and agreeable. So far as I know, there is no place in Peru where the ruins consist of anything like a "masonry wall with three windows" of such a ceremonial character as is here referred to, except at Machu Picchu. It would certainly seem as though the Temple of the Three Windows, the most significant structure within the citadel, is the building referred to by Pachacuti Yamqui Saleamayhua. ------ FIGURE The Masonry Wall with Three Windows, Machu Picchu ------ The principal difficulty with this theory is that while the first meaning of tocco in Holguin's standard Quichua dictionary is "ventana" or "window," and while "window" is the only meaning given this important word in Markham's revised Quichua dictionary (1908), a dictionary compiled from many sources, the second meaning of tocco given by Holguin is "alacena," "a cupboard set in a wall." Undoubtedly this means what we call, in the ruins of the houses of the Incas, a niche. Now the drawings, crude as they are, in Sir Clements Markham's translation of the Salcamayhua manuscript, do give the impression of niches rather than of windows. Does Tampu-tocco mean a tampu remarkable for its niches? At Paccaritampu there do not appear to be any particularly fine niches; while at Machu Picchu, on the other hand, there are many very beautiful niches, especially in the cave which has been referred to as a "Royal Mausoleum." As a matter of fact, nearly all the finest ruins of the Incas have excellent niches. Since niches were so common a feature of Inca architecture, the chances are that Sir Clements is right in translating Salcamayhua as he did and in calling Tampu-tocco "the hill with the three openings or windows." In any case Machu Picchu fits the story far better than does Paccaritampu. However, in view of the fact that the early writers all repeat the story that Tampu-tocco was at Paccaritampu, it would be absurd to say that they did not know what they were talking about, even though the actual remains at or near Paccaritampu do not fit the requirements.
