Dryads in Wikipedia
Dryads (Δρυάδες, sing.: Δρυάς) are tree nymphs in Greek
mythology. In Greek drys signifies 'oak,' from an Indo-
European root *derew(o)- 'tree' or 'wood'. Thus dryads are
specifically the nymphs of oak trees, though the term has
come to be used for all tree nymphs in general. "Such deities
are very much overshadowed by the divine figures defined
through poetry and cult," Walter Burkert remarked of Greek
nature deities. They were normally considered to be very
shy creatures, except around the goddess Artemis, who was
known to be a friend to most nymphs...
