Yes I'm aware of them - and they add to my wonder: Why were the Inca so innovative?

As I understand them, quipu did not transmit words, so how do you communicate, for example, rope bridge construction and maintenance information over great distances and time.

Your question has been answered before in this thread. You communicate rope bridge construction and maintenance via apprenticeship. There is a master rope bridge builder who teaches personaly by demonstration and telling an apprentice rope bridge builder, then supervises their work for a bit before the apprentice is declared a master themselves. You do not need written communication for this.

In fact even to this day this is how much of the skills are communicated. I learned lost wax casting from a dude in a workshop who shown me what should be the proper consistency of the malachite-gypsum-water mixture before you slop it on your wax pieces. I didn’t learn it from a book, even though i know how to read and read a lot. Similarly i learned from a master (a different one) during personal supervision on how silver glows when it is just perfect temp to flow into a cast. Also learned from a master how to see that the metal I’m working is becoming brittle from work hardening, and what can I do to avoid or even use that effect to my benefit. None of this is rope bridge building, just illustrations that knowledge, even very important knowledge, is transmitted to this day without writing.

Why is it so hard to imagine that the Incas did the same?

What a bizarre conversation - I could understand one person not quite fathoming the question, but all these people insisting is really odd.

This thread doesn't explain the Incas at all for reasons I explained (but which should be obvious). What I'm asking are well-established, prominent subjects of research.

And then people playing down literacy ... is this that anti-modernism trend - the Middle Ages were fine, secret prehistorical societies had advanced technology, who needs literacy, etc.? It's just hard to fathom.

I'm not sure I'm (I'll speak only for myself in this thread) am 'playing down literacy'. It's great, we should have more of it. No questions asked.

Maybe there's a tone interpretation issue in the thread... 'How did the Incas do this' -- is that asking for the detailed specifics of their management culture and systems (mostly unknowable -- likely the subject of a many past and future academic careers), or is it a statement of incredulity. I think myself and most of the other commenters have interpreted the latter, whether that was your intention or not.

What I'm pointing out is that, if you've seen much of the developing world, or lived anywhere except the fully formed bubble of a 'modern developed society,' you will have had the opportunity to observe that 'life... (and by extension, civilization)... find a way.'

The Egyptian pharoahs ruled for over 3000 years. That number is unfathomable in the context of modern society. Yes they had a written language, but the vast majority of that empire very likely did not know how to read it.

The millions that lived through that era integrated, obeyed and functioned into that power structure for more than 1.5x the time since we all agreed on a numbering structure for 'years since some arbitrary point in the past.'

Christianity, and Hinduism, and Islam, and frankly every major religion spread, and brought most of humanity into their fold without most of its adherents being able to read. There wasn't a formal written bible until hundreds of years after the religion itself was formed. It passed through dozens of generations before being formalized.

All this is to say: I don't know how the Incas did it, in terms of the granular specifics of their culture and systems, but that they did it, somehow, and using methods quite normal for most of history, is far from implausible.

I understand now. No, not incredulity at all, but serious questions. It's an exceptional, very rare achievement. I was hoping for some research out there already that someone was aware of.

> I was hoping for some research out there already that someone was aware of

I think this thread got very heated, but fundamentally

1. Oral transmission via an apprentice system - a common method used throughout much of history, as mass illiteracy was the norm for most societies at the local level until the 18th-19th century

2. Quipus as a form of proto-writing - we know the Inca were able to codify and communicate categorical and numerical data using quipus. Hypothetically, they might have even been able to use quipu knots to represent an alphabet.

We simply wouldn't know because the Spanish burnt most Quipus during the inquisition and the aftermath of the conquest of the Neo-Inca State in the late 16th century and the failure of Tupac Amaru II's rebellion against the Spanish at the end of the 18th century.

The Spanish conquest of the Andes was heavily genocidal compared to their other conquests (that's saying something). It almost compared to the ferocity with which the Moriscos (Iberian Muslims) and Sephardim (Iberian Jews) were genocided in the 16th century.

To this day the Quechua homeland in Bolivia and Peru remain the least developed regions of South America, with HDIs comparable to those found in poorer states of India and China, compared to much of South America's (excluding Venezuela due to their collapse) HDI converging around 0.800-0.850.

Thanks. Are you summarizing the thread or is that based on evidence and research? I don't see the explanatory power of those theories.

> Oral transmission via an apprentice system

Oral transmission has probably existed everywhere (apprenticeship is a matter of definition, but I get the idea), but very few have achieved anything like the Incas.

> Quipus as a form of proto-writing

Quipus are just numbers, as far as I know. They are great, but don't explain how the enormous amount of other necessary information is transmitted and updated across such a vast geography.

With due respect, what we need is actual research based on actual evidence, not Internet comments (I'm not offering any theories myself!).

If everyone is misunderstanding your question then maybe the problem is with how the question is formed.

> This thread doesn't explain the Incas at all

Yeah. Nobody is going to explain a whole civilisation with everything involved in a few short sentences. You were asking specificaly how the bridge building knowledge was spread without literacy. That is what was explained to you. Repeatedly.

> And then people playing down literacy

Nobody is “playing down literacy”. It is just clear from your question that you do not understand how something can happen without it. So I have pointed out examples where skills are transmitted without reading/writing. It is called tacit knowledge and it has a huge role in all kind of skills and technology.

> the Middle Ages were fine, secret prehistorical societies had advanced technology, who needs literacy, etc.?

What are you talking about? Why are you making things up?

> It's just hard to fathom.

I can say the same about your weird whatever that list is.
