The ancient Chinese were the world’s first and best astronomers. Carl Sagan dates their astronomical record-keeping back to 1500 BC. Star catalogues listed hundreds of comets over hundreds of years, and included detailed information on dates, appearance, and location of comets.
The Chinese drew up the world’s first cometary atlas, too, the Mawangdui Silk, as it’s called, ca. 300 BC. Here’s a portion of it:
And here’s one of my favorite entries from the “Record of the World’s Changes,” by Li Ch’un, 602-667:

“The people hate life and don’t even want to speak of it.” Indeed.
