In Greek mythology, Ianthe (Ancient Greek: Ἰάνθη Ianthê) or Janthe[1] was one of the 3,000 Oceanids, water-nymph daughters of the Titans Oceanus and his sister-spouse Tethys.[2][3][4] Her name means ‘she who delights’,[5] or probably from ianthên 'heat' or ianthos 'violet'.
Along with her sisters, Ianthe was one of the companions of Persephone when the daughter of Demeter was abducted by Hades.[6]
