Why Horses are Better than Llamas
Brad DeLong has had several excellent posts recently on Jared Diamond’s Guns, Germs, Steel (see here and here). Here is my thousand words from Lima’s National Museum of Archaeology, Anthropology and History.
What I believe this shows is how an Incan/Andean would ride a Llama, the peculiar postion being necessary because Llamas are not very strong and this is the best way to spread one’s weight across the Llama’s back. The caption did read "Llama usado como transporte" but I could not find any other information.
