In Greek mythology, Nesaea, Nesaia or Nisaea (Ancient Greek: Νησαίη Nêsaiê means 'the dweller on islands'[1]) was the "white" Nereid of islands,[2][3] one of the 50 marine-nymph daughters of the "Old Man of the Sea" Nereus and the Oceanid Doris.
[4] Nesaea was one of the Nereids who gathered round Thetis in her sympathetic grief for Achilles' loss of Patroclus.
[5] In some accounts, Nesaea, together with her sisters Thalia, Cymodoce and Spio, was one of the nymphs in the train of Cyrene[6] Later on, these four together with their other sisters Thetis, Melite and Panopea, were able to help the hero Aeneas and his crew during a storm.
[7] This name is used to describe a genus of plants in the family Lythraceae.
