Nymph: singular, a nature spirit in the Greek pantheon
Nymphai: plural form of nymph
First, let’s talk about what a Nymph is. A nymph is usually described as a ‘lesser’ Goddess in Hellenism. They tend to be localized nature spirits, though that’s not the only type of Nymph out there. What does that mean for your worship? Well, it means that most Nymph worship is going to be for the specific Nymphai in your area. While you may choose to worship some more famous Nymphai and ones from other areas, you’re likely to find that there are plenty in your own area that you can worship as well.
Here are some types of nymphs connected to nature:
Alseides (nymphai of glens and groves)
Anthousai (flower nymphs)
Auloniades (nymphai of pastures)
Crinaeae (nymphai of fountains)
Daphnaeae (laurel tree nymphai)
Dryades (nymphai associated with trees)
Epimeliades (nymphai of highland pastures, protectors of flocks)
Haliai (nymphai of shore lines)
Hamadryades (oak nymphai)
Heleionomai (nymphai from wetlands)
Hesperides, the (nymphai of sunset)
Hyades, the (celestial nymphai of the constellation Aquarius)
Leimakides (nymphai of meadows)
Limnades (nymphai who reside in lakes)
Meliades (apple tree nymphai)
Meliai (nymphai of honey, bees, and ash trees)
Naiads (fresh water nymphai)
Napaeae (mountain valleys)
Nereids (ocean nymphai who are the daughters of Nereus)
Oceanids (ocean nymphai who are daughters of Oceanus)
Oreads (nymphai of grottoes)
Pagaeae (nymphai who belong to springs)
Pleiades (yup, like the constellation)
Potameides (river nymphai)
The second type of Nymphai are those who are associated with cities, or who serve in retinue to a specific Theos. Such as:
Lampades (torch bearer nymphai in retinue to Hekate)
Maenads (nymphai in retinue to Dionysos)
For the purpose of this post I’m going to talk about the Nymphai connected to the earth and nature.
Some Nymphai are specifically named in myth. These are usually Nymphai who are associated with specific plants, but also one’s who’ve played a role in a Theos’ story at one point or another, and one’s who are patrons to specific towns and cities. This is just a sampling of some of the Nymphai who are named in myth.
Aba- Naiad of the town Ergisce in Ciconia, Thrace
Aigeiros- Hamadryad of black poplar
Asopis- Naiad Nymph of a town by the same name
Balanos- Hamadryad of evergreen oak
Bateia- Naiad of Sparta in Lacedaemonia
Daphne- Naiad who became the laurel tree
Io-Argive Princess and Naiad who was loved by Zeus
Karya- Hamadryad Nymph of nut trees, including hazelnut, walnut, and chestnut
Khloris- Oceanid and Goddess of flowers
Klytie- Oceanid who loved Helios and transformed into the heliotrope flower when He left Her
Kraneia- Hamadryad Nymph of cherry trees
Leuke- the white poplar tree
Lotis- Naiad who transformed into the lotus

Ptelea- Hamadryad of elm trees
Syke- Hamadryad of fig trees
How to Worship Nymphai: Building a Shrine or Altar
When you’re talking about worship in Hellenism, a lot of people think about shrines and altars, since they give us a place to actually give offerings. Altars were historically built with the idea in mind of “how do I get this offering to the Theos it belongs to?” That means that Ouranic (heavenly) altars were raised up towards the sky. Khthonic (relating to the earth and death) altars were usually dug into the ground as the Khthonic Theoi were thought to reside under ground.
Altars for entities like Heroes and Nymphai were kind of odd. Some people would build them as khthonic altars, some people would build them as Ouranic, and it was’t uncommon to find that their worship was mixed with elements of both Ouranic and Khthonic ritual. Shrines and altars to the nymphai were almost exclusively built outside though from what I’ve seen. They were also built near where a Nymph was thought to reside when possible.
Personally, I like to have my altar for the local Nymphai outside, and raised up, similarly to how Ouranic altars are built. You don’t have to do it that way, it’s just the way I handle it. I also try to build any altars dedicated to the Nymphai with natural materials. So, for example, an altar for the local Nymphai in my area may be a flat stone on the edge of the forest near my home.
Since Nymphai are regarded as living in or around the area where you would be making offerings, the need for Ouranic ritual, which is designed to send the offerings upwards, isn’t really there. There’s two ways I’d say you could approach this.
The first would be that you can give offerings in a khthonic manner, since Nymphai are khthonic in their connection to the Earth. This would mean pouring libations to the soil, and either burning or burying other offerings.
The other way you can approach offerings is to simply set any offerings before your altar or shrine, and leave them there for the Nymphai. An example of this would be to set an apple on your shrine as an offering, and leave it for a set amount of time before cleaning it up. If you are leaving offerings outside in local habitats be sure that you're using foods or plants already native to the area, and things that won't poison any animals who might eat it up.
Personally, I follow khthonic ritual when giving offerings to the Nymphai. I pour libations into the soil, I bury fruit, and I give the offering in it’s entirety to the Nymphai. I don’t consume any of what is meant for the Nymphai. Again, you don’t have to do things the way I do.
Any of the classic offerings can be given to Nymphai. These include:
Statues (please don't be littering and leaving statues in the woods though)
You can also give them offerings from the surrounding area. If you have blueberries that grow wild in the area, then blueberries may prove to be a great offering. Again, I suggest sticking with things that are natural. Since Nymphai are nature spirits, giving them something plastic may not go over real well, especially if you’re leaving the offering outside in nature. Basically, be sure you’re not littering and leaving things that aren’t going to decompose when leaving offerings in nature. And please make sure you're not accidentally introducing invasive species of plants via fruit/seeds/ect.
Devotional activities would probably relate closely to the Nymph in question, though I do have a few general ideas.
Clean up the area where you believe the Nymph resides
Get involved in local conservation efforts
Go on nature walks and admire the influence and beauty of the Nymphai in your area
Nymphs, like many rustic deities, were considered to be connected to prophecy. Nympholepts were devotees of local Nymphai who also worked as prophets. Astragaloi, a form of divination using knuckle bones from sheep, was popular for communicating with Nymphai, and sets of astragaloi bones have been found in multiple caves where Nymphai were worshiped.
That’s certainly not the only option you have though when approaching Nymphai with the intent of divination and prophecy, and a little exploration and trial & error may turn up local Nymphai willing to communicate via other methods of divination.
