I've been really interested in pre-colonial american history recently amongst other ancient societies. I even wrote an essay recently on the origins and meaning of the cave motif in Olmec altar thrones. In short, I believe it materially comes from the fact that the Olmecs had only relatively recently left cave dwellings and temporary housings to form the first cities in the Americas. However it also served the purpose of legitimizing the power of the Olmec rulers as caves were very religiously significant. Other mesoamerican mythologies viewed caves as a place that is close to Xibalba, the Mayan form of underworld. Xibalba was viewed as a place like earth that resided within the primordial sea through which the middle world (viewed as a creature drifting in the primordial sea) floats. Xibalba was full of people and creatures which could be communicated with and even bargained with. The shaman-rulers of Olmec society would likely consume hallucinogens and/or deliriants like Datura and then either enter or sit at the entrance of the cave to communicate with Xibalba. Knowing the effects of Datura and plants like it, this had to have been an incredibly unpleasant and probably terrifying experience. I am doubtless that the feat was considered brave. Anywho, the Olmec rulers would have a cave carved at the front and center of their throne, often with someone standing in front of it or exiting it. Fun fact: Sometimes, likely after or slightly before the death of that ruler, their throne would be turned on its side so that it is vertical and carved into what may be the face of that ruler. You can still see the scar of the cave carving on the side of the head for some of them. Here's some pictures!

I also love the Incans but I know less about them. Their textiles are wonderful though.
