The Nymphs were imagined as beautiful girls and were divided into several categories: the Nereidis were Nymphs of the sea, the Nyads were of the rivers and springs, the Oryads were of the mountains and canyons, while the Dryads were the Nymphs of the trees. The Nymphs never got older, but they weren't all immortal because they lasted as long as the element of nature which they protected. The Nymphs are the protagonists of many love stories with gods and men. Those which didn't want to fall in love followed Artemis in his hunting.
