This isn't entirely right. Back then, Astronomy was your calender for the most part, everyone had at least a working knowledge of moon cycles, and the major visible planets. Comets, while extremily rare, were known as a disctinct phenomenon. While it is true they had tons of myths about comets being an evil sign, comets were comets. Similarly, planets were planets.
So, how do any of these things inspire a midevil painter to paint an image of a metallic egg-shaped object with a pilot onboard?
So people know less now than they did then? Is that what you are saying? That 'everyone' statement is a bit dangerous, is that what you really meant?
Comets, shooting, stars, etc, are not rare. With less light pollution than today, they'd have been far more visible. So any one of these fairly regular sightings could inspire anyone to come up with all manner of art. I mentioned 'artistic impression' earlier in the thread. The object witnessed most likely bore no resemblance to what was painted.
A link to that picture would be good, too. And it's 'medieval', btw.
