f68r: eclipse from 1419?

[oshfdk]

It appears it was possible. I got this from Gemini:

This doesn't include any specific citations though and the text seems to suggest that somehow it was possible in the XV century to compute whether an eclipse would be visible in Europe or not, which I think wasn't possible until three hundred years later when Newtonian mechanics of the solar system allowed for precise enough computations of the orbits.

Saros tables existed before the XV century at least in the Arabic/Greek world, but these only covered the eclipse series for which precedents (past eclipses in the same series) had been recorded. We need an example of a saros eclipse table from the XV century Europe, I haven't seen any yet.

Overall, how sure are you of the validity of this analysis by Gemini?
