Diana (same as Artemis) was not only the goddess of hunting, but was considered--at least in Asia and in many other places around the Graeco/Roman world--to be the "mother goddess" of all nature, much like Gaia, the goddess currently being widely promoted as Mother Earth in the New-Age movement. The temple of Diana at Ephesus was so magnificent that it was considered one of the "seven wonders of the world" in ancient times.
