But again, the list continues. The tomb of the Egyptian King Unas contained a hymn in praise to the king as a cannibal. Cannibalism was routine in Roman sieges, the Crusades, as well as in China during the Tang dynasty, where cannibalism included eating an enemy's heart and liver as punishment. Now many attribute cannibalistic rituals to the Mesoamericans. Now there is evidence of human sacrifices being part of that culture, but there is no evidence of cannibalism. And many reports of cannibalism against the islanders of the Caribbean and the cultures of the New World were first made by Christopher Columbus himself. So they must be evaluated with a critical eye, as this information was being fed to Europe to depict the inhabitants of the New World as savage animals, justifying genocide.
