Answer :
Final answer:
C. The Lost City of Z's legend originated from a document called Manuscript 512. Mesopotamians called the Indus Valley civilization 'Meluhha,' while the cities likely had citadels as ceremonial centers. The Muisca people's rituals led to the El Dorado myth.
Explanation:
The mythical location whose legend began due to the discovery of a document known as Manuscript 512 is c. the Lost City of Z. This document, supposedly authored by João da Silva Guimarães, was discovered in the archives of the National Library of Brazil. It describes a grand and rich city in the Brazilian jungles, which may have inspired subsequent searches for this legendary city, similar to those hunts pursued for the fabled El Dorado.
Regarding the other historical questions, the Mesopotamians referred to the Indus Valley civilization as a. Meluhha, and the monumental ceremonial centers in Indus Valley cities were most likely c. citadels. The Muisca people, who did not have a writing system, performed religious rituals that eventually fueled the myth of El Dorado, which the Spanish sought as a city of gold without success.
