The Great Race: Why the Zodiac Animals Are in That Order
Every Chinese zodiac guide starts with the same folk tale, and it explains the order of the animals better than any list.
The Jade Emperor announced a race across a wide river. The first twelve animals to cross would each get a year of the calendar named after them, in the order they finished.
The Rat could not swim well, so it rode on the back of the kind-hearted Ox. Just before the far bank, the Rat jumped off and scampered to the finish first — which is why the Rat leads the cycle and the reliable Ox comes second. The powerful Tiger struggled against the current and arrived third. The Rabbit hopped across on stepping stones and a floating log, finishing fourth. The Dragon could have flown straight there but stopped to bring rain to a village and to blow the Rabbit's log to shore, so it came fifth. The Snake had hidden around the Horse's hoof; it slithered out at the last moment, startling the Horse, and took sixth while the Horse took seventh. The Goat, Monkey and Rooster shared a raft and worked together to cross, finishing eighth, ninth and tenth. The Dog was a strong swimmer but stopped to play in the water, arriving eleventh. Finally the Pig grew hungry, ate, fell asleep on the bank, and woke up just in time to finish twelfth.
The Cat is not in the zodiac at all: in most versions it was tricked or forgotten by the Rat, which is offered as the reason cats and rats have been enemies ever since.
