OLLANTAI (ol-yan-ti'), Peruvian soldier, lived in Cuzco in the 15th or, as some authors assert, in the 8th century. According to tradition and a drama translated from the Quechua language by Jose S. Barranca (Lima, 1862), Ollantai was general of the army of Inca Pachacutic, and fell in love with the inca's daughter, Cuci-Ccoyllar, who returned his passion, but the father refused her hand to his subject. The priests, to whom the inca applied, were unable to cure the princess of her love, and when the latter informed her lover that she was about to become a mother, Ollantai revolted against his sovereign and shut himself up in the fortress Ollantaitamba, the colossal ruins of which still exist near Cuzco. Pachaeutic died of sorrow over the dishonor of his daughter in 1423, and his successor, Inca Yupanqui, besieged the fortress with his whole army and captured the rebel, whom, together with the princess, he kept prisoner for many years. At last, when their daughter, Ima Sumac, had grown to womanhood, she obtained from her uncle the pardon of her parents, and the inca gave his sister in marriage to Ollantai. There exists scarcely a doubt of the truth of these facts, but Tschudi, Rivero, and other investigators of inca history contend that the drama is only a version of an extremely old popular tradition, and that Barranca adapted it to the reign of Pachacutic and Yupanqui.
