The Ceryneian Hind was an animal held sacred to Artemis. It was so fast it could outrun an arrow. It had golden antlers and so was called the Golden Hind. Eurystheus requested the capture of this animal as part of Heracles' third labor. This task was requested in a bid to have Heracles earn Artemis' distaste.
Heracles tracked the animal for one year on foot. When he finally trapped it, Artemis and Apollo appeared to him. Heracles begged forgiveness and requested their mercy as he had to capture the animal as part of his labors. Artemis agreed on condition he release the animal as soon as possible. When Eurystheus attempted to take the animal from Heracles, it darted away back to its mistress.
