Not immediately clear when first observed, I'll bet it wasn't until Cassini got there in 2004.
I appreciate the creativity in a new-to-me conspiracy theory, but be a little more careful about the historical record.
It's quite egotistical and foolish to assume we're more advanced and know more than our ancient ancestors, or that what is written in our history books is objective truth.
In fact, even scholars have suggested that Babylonians could and did observe at least one of Saturn's rings - https://articles.adsabs.harvard.edu/cgi-bin/nph-iarticle_que...
I have a hypothesis, which incorporates the fact that the Dogon were not reported to have such knowledge until the 1930s, well after the discovery of Sirius B.
> depicted in symbolism by different cultures dating back to Babylon
A bit of searching is coming up short, beyond a claim about shackles on the ankles of a Roman statue of Saturn (the god) symbolizing the rings; I find this less convincing than the idea that they symbolize shackles (the ones with which he was bound in Tartaros).
