Who said "I and my companions suffer from a disease of the heart which can be cured only by gold

Hernán Cortés

Explanation:

Hernán Cortés was a Spanish conquistador that took over the Aztec Empire in the name of Charles V.

Cortés orchestrated an expedition in the early XVI century with an aim to explore the New World. His expedition granted the Spanish Empire with the territory of Mexico, ancient Aztec Empire.

This quote was uttered by Hernán Cortés to the delegates of Moctezuma after they had gifted the Spaniards with massive amounts of gold. This only awoke the greed of the future Spanish colonists.
