Hamadryads

Hamadryads are tree nymphs in Greek mythology, a specialized class of dryads whose existence is inseparable from a particular tree. The name is derived from the Greek hamadryas, literally meaning “tree-nymph” or “tree-spirit.”

The life of a hamadryad is bound to the life of her tree: when the tree thrives, she thrives; when the tree dies or is cut down, the hamadryad dies. Because of this bond, hamadryads are often regarded as guardians of their grove rather than independent spirits.

They are typically depicted as female nature spirits associated with forests or groves, with the oak frequently noted as a favored home. They may appear to mortals, warn about danger to the tree, or intervene to protect the grove; their conduct ranges from gentle and shy to protective or even vengeful if their tree is harmed.

In classical sources, hamadryads are cited as part of the broader family of nymphs that inhabit the natural world. The concept also appears in later literature and modern fantasy, where hamadryads are treated as distinct beings tied to particular trees.
