Now Tupac Yupanqui would not be the only Inca who cherished a certain scepticism concerning his ancestor the Sun. Herrera tells us that the Inca Viracocha denied that the Sun was God;[66] and according to a story preserved by Garcilasso,[67] the Inca Huayna Capac, the conqueror of Quito, who died shortly after Pizarro's first disembarkment, must have been quite as much of a rationalist. One day, during the celebration of a festival in honour of the Sun, he is said to have gazed at the great luminary so long and fixedly that the chief priest ventured on some respectful remarks to the effect that so irreverent a proceeding must surprise the people. "I will ask you two questions," replied the monarch. "I am your king and universal lord. Would any one of you have the hardihood to order me to rise from my seat and take a long journey for his pleasure?... And would the richest and most powerful of my vassals dare to disobey if I should command him on the spot to set out in all speed for Chili?" And when the priest answered in the negative, the Inca continued: "Then I tell you there must be a greater and a more mighty lord above our father the Sun, who orders him to take the course he follows day by day. For if he were himself the sovereign lord, he would now and again omit his journey and rest, for his pleasure, even if he experienced no necessity for doing so." Once more: I will not vouch for the exact form of these audacious speculations of the free-thinking Inca. But such reminiscences, collected independently by various authors, correspond to the conjectures forced upon us by the extreme political sagacity of the Incas. None but theocrats, in whose own hearts faith in their central principle was waning, could develop such astuteness and diplomacy. A sincere and untried faith has not recourse to so many expedients dictated by policy and the fear lest the joint in the armour should be found. It is to be presumed, however, that these heterodox speculations of the Incas themselves never passed beyond the narrow circle of the family and its immediate surroundings. Nothing of the kind would ever be caught by the ear of the people. But the evidence as to Huayna Capac's scepticism derives a certain confirmation from the fact that he was the first Inca who departed (to the woe of his empire, as it turned out) from some of the hereditary maxims that had always been scrupulously observed by his ancestors.
