In Greek mythology, the Oreads, or Orestiads, were the nymphs that inhabited mountains, valleys, and ravines, and were sometimes associated with the goddess Artemis. They were often classified from where they dwelled; for example, the Idaeae lived in Mt. Ida, while the Peliades were from Mt. Pelion.
