I seem to recall seeing something about Chinese records of that period. It may have been when I was seeking information about Cassiodorus’ writings of the time.
There's a new find of terracotta figures in a Han Chinese tomb -- but they're miniatures. Pretty neat looking the photo I saw. And the article noted that the ruler had died shortly after a comet (making it possible to date the sighting). They kept good records in China of eclipses, comets, and such, and as their interest was astrological, the records tended to survive.
I didn’t know that!
I will have to do some more reading.
Thank You Very Much!
