If we assume that 1) eclipses were very important visible or not and 2) it was possible to predict this particular eclipse, then the lack of mentions seems strange.
Sure, fair. Yes, approach has been consistent for millennia. Secondly, yes, possible to predict. Most of the work is understanding the behaviour of planetary bodies, it would have no predictive value otherwise. I am not sure that our author did his predictions himself though, if any of these turn out to be charts (horoscopes). Many people have pointed out the sloppiness of his technical drawing, I agree, it looks like my first study notebook. All the circles with missing chunks, overlaps, or terribly uneven angles. They could be teaching diagrams, though.
With regards to contemporary mentions, there are a few points. Astrology almost disappeared in Europe following the 5th century, and when it was revived in the 12th century it relied heavily on Latin translations of Arabic texts. The Arabic texts contained what little had survived from the Hellenists. Many of these Arabic manuscripts were systematically destroyed during the 13th century during the reconquest of Spain. Some astrological works don't fare well in history, at some point they become contentious at best, and heretical at worst.
Eclipses happen often enough and with enough diversity, that each must be appraised on its own merits. A handful every year. Each of them carries a different interpretive meaning. It could have been something mundane and routine, such as a fortuitous eclipse for sowing crops. It could have been personal, such as the eclipse that predated our author's birth. Without knowing what the text says, we are guessing at it, though the 1419 chart can be assessed of course, for whatever good that would do. If You are not allowed to view links.

Anyway, truly not married to the idea of it being 1419. Just wanting to pitch in.
