The Spirit of Here
Genus Loci, Latin for 'the spirit of the place', includes many types of creatures from around the world. They are all, in some way, bound to a location or type of location. Some can be re-bound, others cannot. Genus loci who leave their homes, to travel, almost always carry a piece of their original locale with them, to sustain them, while they are away. The closer they are to home, the more powerful what powers they have will become.
Alseids are the nymphs of glens and groves.
Nymphs of the flowers, most often hyacinth. Their hair is described as being 'like hyacinth flowers'.
Auloniads are found in mountain pastures and vales.
Tree nymphs, most specifically those of oak trees, but now including nymphs of all trees. Other named types of dryads include Caryatids (walnut trees), Meliae (ash trees), and Epimeliads (apple trees).
A type of dryad bonded particularly to a single tree. If the tree were to be injured or died, the dryad would suffer the same fate.
Dryads of the ash tree, born of the spilled blood of Uranus. It is said they were the nursemaids of Zeus.
Nymphs of the sea, the sands, and the rocky shores. This group includes any of the salt-water nymphs. They had the schools of fish, and other sea creatures in their keeping. The most famous of them were the fifty Nereids.
Nereids are the patrons of sailors and fishermen, who come to the aid of men in distress, and look after the sea's rich bounty. They are frequently depicted as beautiful young maidens, sometimes running with small dolphins or fish in their hands, other times riding on the back of dolphins, hippokampoi and other sea creatures. They are specifically linked to the Mediterranean and Aegean, and more broadly to inland seas, as opposed to the Oceanids, who attend to the great oceans.
The Oceanids are the three thousand daughters of Oceanus and Tethys. Each is the patroness of a particular spring, river, sea, lake, pond, pasture, flower or cloud. Some scholars include the Potamoi, the three thousand sons of the same parents, under the term 'oceanids', but I list them separately, under Naiads. Later documents, after the realisation that the ocean was salt water, just like the sea, attribute them as the Haliai of the encircling ocean (as opposed to the 'encircling fresh-water river').
These Haliai are the seven daughters of Atlas and Pleione. They served as nursemaids to Bacchus and guided sailors in the Mediterranean.
Specifically, the nymphs of Hesperia, a garden near the Atlas mountains. They are said to be the daughters of Nyx and Erebus, and whether there are only three of them or not, they appear in threes, whenever they are seen.
The torch-bearing nymphs of the Underworld, who light the path for Hecate on her travels. It is said the light of their torches can drive a man mad.
The nymphs who preside over fountains, wells, springs, streams, brooks, and other freshwater sources. The essence of a naiad is bound to her spring, so if a naiad's body of water dries, she will die.
Crinaeae are naiads of fountains and wells.
Marsh naiads, famed for misleading travellers with their illusions. They are also known for seducing virgin boys who trod too close to their homes.
The naiads of freshwater lakes, said to be parented by the gods of the lake's source, usually a river.
The naiads of a river's springs, they are said to descend from the Potamoi, the gods of those parent rivers.
The naiads of watering holes, especially those made by Pegasus, when he struck his hooves against the ground, while being captured by Bellerophon.
The naiads of rivers and streams, Potamides are generally more specifically classed by the names of their rivers and streams. They are favourably inclined to young women and will remove the freckles from those who bathe in their territories. Toward young men, they are much more aggressive, dragging them down into their homes. Potamides are often credited with minor powers of divination.
The Potamoi are the gods of rivers, the three thousand sons of Oceanus and Tethys. They are the fathers of Naiads, and the brothers of the Oceanids. They are listed with Naiads, because the appellation of 'theoi' is quite broad, in Greek, and they are more correctly a type of genus loci, being linked to their rivers, specifically. Frequently, they are seen as either a man-headed bull or a bull-headed man with the body of a serpent-like fish from the waist down.
A nymph of wooded valleys, glens, and grottoes.
Nymphs that live in mountains, valleys, and ravines. From 'oros', Greek for 'mountain'. They are differentiated by the name of the mountain to which they belong, i.e. the Peliades are from Mount Pelion.
