You're absolutely right—most of the Antikythera-like examples don’t fit the bill since they rely on mechanical devices or routines they could observe directly. You're specifically interested in ''knowledge they had no method to acquire''—like accurate astronomical predictions or astrological insights, but without the tools or math to justify them. That narrows the list significantly to civilizations with legitimate—but puzzling—astronomical foresight. Here are the major ones:

==== - '''What they knew:''' They forecast lunar and solar eclipses via the Saros cycle—approximately every 18 years 11 ⅓ days—based on centuries of naked-eye observations, though they lacked a theoretical orbit model wired.com<ref>{{cite web|title=wired.com|url=https://www.wired.com/story/when-exactly-will-the-eclipse-happen|publisher=wired.com|access-date=2025-12-06}}</ref>eclipsewise.com<ref>{{cite web|title=eclipsewise.com|url=https://skyandtelescope.org/astronomy-news/how-did-the-ancients-predicted-eclipses-the-saros-cycle/|publisher=skyandtelescope.org|access-date=2025-12-06}}</ref>. ====
* '''Why it's mysterious:''' They translated these into detailed omens—"If eclipse happens on X date, disaster for king"—and integrated them into royal decision-making .

==== - '''What they did:''' Recorded eclipses as early as ~2137 BCE, predicting them by correlating lunar cycles. ====
* '''Mystery factor:''' Lacking orbital theory, they still managed reasonably accurate forecasts—else risked execution for failure! eclipsewise.com<ref>{{cite web|title=eclipsewise.com|url=https://www.eclipsewise.com/extra/SEhistoryReis.html|publisher=eclipsewise.com|access-date=2025-12-06}}</ref>.

==== - '''Claimed achievement:''' Predicted a solar eclipse so precisely that it supposedly halted a battle wired.com<ref>{{cite web|title=wired.com|url=https://en.wikipedia.org/wiki/Eclipse_of_Thales|publisher=en.wikipedia.org|access-date=2025-12-06}}</ref>. ====
* '''Dubious yet impressive:''' Mechanism unknown—likely based on Babylonian cycles, but Greek sources credit Thales directly, and yet no concrete method survives.

==== - '''What they did:''' Eclipse tables in the Dresden Codex allowed day‑level prediction. ====
* '''Mystery:''' They developed this without telescopes or telescopic math—purely empirical calendar science nexusnewsfeed.com<ref>{{cite web|title=nexusnewsfeed.com|url=https://nexusnewsfeed.com/article/ancient-mysteries/how-ancient-people-predicted-eclipses-without-modern-science/|publisher=nexusnewsfeed.com|access-date=2025-12-06}}</ref>spaceyv.com<ref>{{cite web|title=spaceyv.com|url=https://www.newscientist.com/article/2422699-first-nations-astronomers-predicted-eclipses-without-using-writing/|publisher=newscientist.com|access-date=2025-12-06}}</ref>.

==== - '''What they knew:''' Texts like ''Surya Siddhanta'' used geometric and trigonometric rules to calculate eclipses. ====
* '''Puzzle:''' The mental transmission of such sophisticated methods, including awareness of lunar nodes (i.e. points where eclipses occur), is remarkable for a pre-telescope, pre-Newtonian era skyandtelescope.org<ref>{{cite web|title=skyandtelescope.org|url=https://modun.blog/321/|publisher=modun.blog|access-date=2025-12-06}}</ref>.

===== - '''Aboriginal Australians & First Nations''' had oral traditions tracking eclipse patterns—even understanding the Moon’s connection to tides—without written records or mathematics nypost.com<ref>{{cite web|title=nypost.com|url=https://www.newscientist.com/article/2422699-first-nations-astronomers-predicted-eclipses-without-using-writing/|publisher=newscientist.com|access-date=2025-12-06}}</ref>. =====
* '''Assyrian/Babylonian omen tablets''' dating from ~763 BCE record eclipses in year-lists, anchoring events precisely—but again using pattern-recognition not theoretical modeling .

==== - Predicting eclipses without orbital mechanics or sighting devices, relying solely on empirical cycles or oral tradition. ====
* Translating celestial observations into meaningful forecasts, used to guide kings, wars, rituals—based on timing alone.

Those are solid candidates for knowledge they couldn’t have “logically” known by modern standards.

Would you like a deeper dive into any of these (e.g., Maya tables, Thales' eclipse, Chinese prediction methods)? I can also show how modern tests confirm their accuracy!
