The Dragon is paired with chen, the fifth earthly branch, whose double-hour runs from seven to nine in the morning and whose phase is earth. It is the only mythical creature among the twelve and much the most prestigious. The Chinese dragon, long, is not the hoard-guarding monster of European legend but a benevolent power of water, rain, rivers and the sea; it was the emblem of the emperor, whose throne, robes and face were spoken of in dragon terms, and the five-clawed dragon was reserved to imperial use. In the sky it is the Azure Dragon of the east, one of the four directional creatures, and its rising in spring was tied to the agricultural year. The traits given to the sign, ambition, confidence, magnetism and a certain refusal to be constrained, follow from this imperial and elemental standing.
Unlike the other eleven animals, none of which is native to China in every case (the tiger and ox are, the dragon of course is not a living creature at all), the dragon's status as a wholly invented composite creature, said to combine features of nine different real animals in later systematised descriptions, snake's body, deer's horns, eagle's claws among them, makes it the clearest instance in the whole cycle of a sign built by cultural imagination rather than borrowed from an actual creature encountered in daily life, which is part of why it alone required elevation from popular animal folklore to the exclusive property of the throne.
