Nymph
In Greek mythology, a nymph is a large class of female nature spirit, sometimes bound to a particular location or landform. Nymphs often accompanied various gods and goddesses, and were the frequent target of lusty satyrs.
They are personifications of the creative and fostering activities of nature. The word is possibly connected with the root of vt os, nubes ("cloud"), and originally meant "veiled," referring to the custom of a bride being led veiled from her home to that of the husband: hence, a married woman, and, in general, one of marriageable age. Others refer the word (and also Latin nubere and the German Knospe) to a root expressing the idea of "swelling" (according to Hesychius, one of the meanings of vvn r/ is "rose-bud"). The home of the nymphs is on mountains and in groves, by springs and rivers, in valleys and cool grottoes. They are frequently associated with the superior divinities, the huntress Artemis, the prophetic Apollo, the reveller and god of trees Dionysus, and with rustic gods such as Pan and Hermes (as the god of shepherds).
The different species of nymph were distinguished according to the different spheres of nature with which they were connected. Sea nymphs were Oceanids or Nereids, daughters of Oceanus or Nereus. Naiads (from the Greek vaeiv, flow, cf. va^.o., "stream") presided over springs, rivers and lakes. Oreads (opos, mountain) were nymphs of mountains and grottoes, one of the most famous of whom was Echo. Napaeae (vairri, dell) and Alseids (aXcros, grove) were nymphs of glens and groves. Dryads or Hamadryads were nymphs of forests and trees.
The Greek nymphs, after the introduction of their cult into Latium, gradually absorbed into their ranks the indigenous Italian divinities of springs and streams (Juturna, Egeria, Cavmentis, Fons), while the Lymphae (originally Lumpae), Italian water-goddesses, owing to the accidental similarity of name, were identified with the Greek Nymphae. Among the Romans their sphere of influence was restricted, and they appear almost exclusively as divinities of the watery element.
