Nymphs are mythological spirits in ancient Greek and Roman mythology, often associated with nature. They are typically depicted as beautiful young women who inhabit various natural elements, such as rivers, trees, and mountains. Each type of nymph is linked to a specific aspect of nature, like Naiads for freshwater, Dryads for trees, and Oreads for mountains. These beings are usually portrayed as playful and benevolent, often interacting with gods and mortals. Nymphs are not immortal but can live for a very long time, and they are often seen as symbols of fertility and the beauty of the natural world.
