A dryad is a tree nymph or tree spirit in Greek mythology. Drys signifies "oak" in Greek, and dryads are specifically the nymphs of oak trees, but the term has come to be used for tree nymphs in general, or human-tree hybrids in fantasy. They were normally considered to be very shy creatures except around the goddess Artemis, who was known to be a friend to most nymphs.
Types
Daphnaie
These were nymphs of the laurel trees.
Epimelides
The Maliades, Meliades or Epimelides were nymphs of apple and other fruit trees and the protectors of sheep. The Greek word melas—from which their name derives—means both apple and sheep. Hesperides, the guardians of the golden apples were regarded as these type of dryad.
Hamadryad
Dryads, like all nymphs, were supernaturally long-lived and tied to their homes, but some were a step beyond most nymphs. These were the hamadryads who were an integral part of their trees, such that if the tree died, the hamadryad associated with it died as well. For these reasons, dryads and the Greek gods punished any mortals who harmed trees without first the tree-nymphs.
The dryads of the ash tree were called the Meliae. The Meliae sisters tended the infant Zeus in Rhea's Cretan cave. Gaea gave birth to the Meliae after being made fertile by the blood of castrated Uranus. The Caryatids were associated with walnut trees.
Names
Some of the individual dryads or hamadryads are:
Atlanteia and Phoebe, two of the many wives or concubines of Danaus
Dryads are mentioned in Milton'sParadise Lost, in the works of Coleridge, and in Thackeray's novel The Virginians. Keats addresses the nightingale as "light-winged Dryad of the trees", in his "Ode to a Nightingale".In Ezra Pound's Pisan Cantos, Canto LXXXIII. In the poetry of Donald Davidson they illustrate the themes of tradition and the importance of the past to the present. The poet Sylvia Plath uses them to symbolize nature in her poetry in "On the Difficulty of Conjuring up a Dryad", and "On the Plethora of Dryads".
