The Conde de Nieva did not long enjoy the happiness he expected in his government, and he came by his death not many months afterwards by means of a strange accident, of which he was himself the cause; but as it was of a scandalous nature I do not chuse to relate the particulars.

After his death, however, in 1561, his successor, Don Zuñiga, Count de Nieva, was assassinated almost as soon as he took possession of his post. It was during the government of one of Zuñiga's successors, Toledo, that the young Inca, Tupac-Amaru, was executed in the great central square of Cuzco. The horror which this act is said to have instilled in the minds of the Indians is indescribable.

On the death of Don Diego de Azevedo, Don Diego de Zuniga by Velasco, Conde de Nieva, was appointed to supersede the Marquis of Cannete as viceroy of Peru, and departing from Spain to assume his new office in January 1560, he arrived at Payta in Peru in the month of April following.

The Relaciones, so often cited in this History, were prepared at the suggestion of the viceroys, the first being addressed to the Marques de Canete, in 1561, and the second, ten years later, to the Conde de Nieva.

The central chain, that of the Paramos de Callacalla, and Piscoguanuna, scarcely attains 1800 toises, and lowers gently to 800 toises; so that the mountainous and temperate tract of country which extends on the north of Chachapoyas towards Pomacocha, La Vellaca and the source of the Rio Nieva is rich in fine cinchona trees.
