This confusion and rivalry of the Peruvian gods has left its traces in the crude and obscure legend of the Collas, or mountaineers of Pacari Tambo, to the south-west of Cuzco. "From the caves of Pacari Tambo (i.e. 'the house of the dawn') issued one day four brothers and four sisters. The eldest ascended a mountain, and flung stones towards the four cardinal points, which was his way of taking possession of all the land. This aroused the displeasure of the other three. The youngest of all was the cunningest, and he resolved to get rid of his three brothers and reign alone. He persuaded his eldest brother to enter a cave, and as soon as he had done so closed the mouth with an enormous stone, and imprisoned him there for ever." This seems to refer to the quasi-subterranean cultus of Pachacamac, the internal fire, the first revelation of whom must have been a volcano hurling stones in every direction.--"The youngest brother then persuaded the second to ascend a high mountain with him, to seek their lost brother, and when they stood on the summit he hurled him down the precipice and changed him into a stone by a spell." I cannot say to what special deity this part of the legend alludes, unless it simply refers to an ancient worship of stones or rocks, many vestiges of which remained under the Incas, though it ceased to have any official importance in presence of the radiant worship of the Sun promulgated and favoured by the ruling family.--"Then the third brother fled in terror." This fleeing god must be Viracocha, the god of showers, who flees before the Sun.--"Then the youngest brother built Cuzco, caused himself to be adored as child of the Sun under the name of Pirrhua Manco, and likewise built other cities on the same model."[84] This last trait puts it out of doubt that the legend is really an attempt to explain how the religion of Manco Capac established at Cuzco had succeeded in eclipsing all others, owing to the superior skill of its priesthood. It is a formal confirmation of all that I have told you of the consummate art with which the Incas gradually extended the circle of their political and religious dominion. _Pirrhua_ is the contraction of Viracocha, taken in the generic sense of "divine being." Pirrhua Manco was an alternative name of Manco Capac. Of course this legend was not officially received under the Incas. The latter, being unable or unwilling to abolish the worship of Viracocha and of Pachacamac, took up a far more conciliatory attitude than that of the legends I have given. The supreme god, the Sun, was admitted to have had three sons, Kon or Viracocha, Pachacamac and Manco Capac; but the latter was declared to have been quite specially designed by the common father to instruct and govern men. By this arrangement every one was satisfied,--and especially the Incas. III. We may now return to the other deities who were officially incorporated in the family or retinue of the Sun.
