He was not aware how precarious was his own tenure of life. Pizarro saw more and more clearly that, in order to become the real master of Peru, he must get rid of the reigning Inca, and put some child in his place, who would be a passive instrument in his hands. He was fairly alarmed by the religious obedience, timid but absolute, that the "child of the Sun," even in his captivity, received from all classes of his subjects. He fancied that from the recesses of his prison, and even while paying off his enormous ransom,[70] Atahualpa had sent secret orders to the most distant populations to arm themselves and come to his rescue. The interpreter through whom he communicated with his captive was out of temper with his master, for his head had been so turned by ambition, that he had demanded the hand of a _coya_, that is to say, one of the Inca's women, and had been haughtily refused. In revenge, he made malicious reports to Pizarro. But it was an accidental circumstance that brought the latter's ill-will towards his captive to a point. The Inca greatly admired the art of writing when he discovered all the uses the Spaniards made of it. One day it occurred to him to get one of the soldiers on guard over him to write the word _Dio_ upon his nail, and he was delighted and astonished to find that every one to whom he showed it read it in the same way. So they told him that every one a little above the common herd could read and write in Europe. His evil star would have it that he showed his thumb one day to Pizarro, who could make nothing of it. Pizarro, then, could not read! Atahualpa concluded that he was merely one of the common herd, and found an opportunity of telling him so. Pizarro, stung to the quick, hesitated no longer. A mock judgment condemned Atahualpa to the extreme penalty for the crimes of idolatry, polygamy, usurpation, fratricide and rebellion. In vain he appealed to the King of Spain. He was led to the stake, and Father Valverde made him purchase by a baptism _in extremis_ the privilege of being strangled instead of burned alive.
