There is next another scene in the garden of the convent, in which Yma
Sumac importunes Pitu Salla to tell her the secret of the prisoner.
Pitu Salla at last yields and opens a stone door. Cusi Coyllur is
discovered, fastened to a wall, and in a dying state. She had been
imprisoned, by order of her father, Inca Pachacuti on the birth of Yma

Next the Inca Tupac Yupanqui is discovered in the great hall of his
palace, seated on his tiana or throne, with the Uillac Uma in

himself enters and receives the thanks of his sovereign. Then the
prisoners are brought in guarded-Ollantay, Hanco Huayllu, Urco Huaranca,

asks the Uillac Uma for his judgment. The High Priest recommends mercy.
Rumi-naui advises immediate execution: The Inca seems to concur and they
are ordered off, when suddenly the Inca cries 'Stop.' He causes them
all to be released, appoints Ollantay to the highest post in the empire

consents to go with the child.

The final scene is in the gardens of the convent. The Inca enters with
