Apparently this is a monument to the Inca nobleman Cahuide
...an Inca nobleman and warrior of the 16th century (1536) in Cuzco, Peru, who participated in the battle of Sacsayhuamán, led by Manco Inca. In one of his battles when the castle he was defending fell into the hands of Conquistador, he jumped from the top of one of the three towers of Sacsayhuamán, called Muyuq Marka, so as not to surrender to his enemies.
Reportedly the sculpture is by three brothers: Luis Alberto Yanqui Yucra, Raúl Oswaldo Yanqui Yucra, and Rodolfo Edwin Yanqui Yucra, and it was made fairly recently (source in Spanish).
The name of the sculpture is "Cahuide against the Spaniard". Here's a picture of the sculptors with the statue:
There is nobility in the resistance. We don't say "LOL Warsaw Uprising was lame because they lost". We lionize it, because men and women took it into their own hands to defend themselves against impossible odds. Likewise we should see the Inca and Neo-Inca.
Fuck the Aztecs though. No sympathy for them, only sympathy for their vassal states and neighbors that got screwed.
