In Greek and Roman mythology, the Oceanids (Ὠκεανίδαι, pl. of Ὠκεανίς) were the three thousand daughters of the Titans Oceanus and Tethys. One of these many daughters was also said to have been the wife of the god Poseidon, typically named as Amphitrite. Each of these nymphs was the patroness of a particular spring, river, ocean, lake, pond, pasture, flower or cloud. Oceanus and Tethys also had 3000 sons, the river-gods Potamoi (Ποταμοί). Whereas most sources limit the term Oceanids or Oceaniades to the daughters, others include both the sons and daughters under this term.[1] Sibelius wrote an orchestral work called Aallottaret (Oceaniades) in 1914.
