What does the constellation Draco represent in mythology?

In mythology, the constellation Draco represents a dragon. This is rooted in various ancient myths and stories, most notably the Greek myth involving the dragon Ladon, which guarded the golden apples in the Garden of the Hesperides. According to some interpretations, Draco is also associated with the tale of Cadmus, who transformed into a dragon after being pursued by one. The depiction of Draco as a serpent or dragon in the night sky aligns with its name, which means 'dragon' in Latin. This connection to dragon mythology highlights its significance in various cultures, reinforcing the idea that the night sky is rich with stories and personifications drawn from human imagination.

The other options do not represent Draco accurately, as there are no significant mythological connections of this constellation to a wolf, snake, or knight in the traditional context of its stories. The focus on a dragon aligns well with the historical and cultural understanding of this particular constellation.
