Nine Daughters of Ægir and Rán

In Norse mythology, the Æsir goddess Rán and the jötunn Ægir both personify the sea, and together they have nine daughters who personify the sea waves, the names of their daughters are poetic terms for sea waves. The sisters are attested in the Poetic Edda, compiled in the 13th century from earlier traditional sources; the Prose Edda, composed in the 13th century; and in the poetry of skalds.
