aegir (mythology)

Ægir (anglicised as Aegir; Old Norse 'sea'), Hlér (Old Norse 'sea'), or Gymir (Old Norse less clearly 'sea, engulfer'), is a jötunn and a personification of the sea in Norse mythology. In the Old Norse record, Ægir hosts the gods in his halls and is associated with brewing ale. Ægir is attested as married to a goddess, Rán, who also personifies the sea, and together the two produced daughters who personify waves, the Nine Daughters of Ægir and Rán, and Ægir's son is Snær, personified snow. Ægir may also be the father of the beautiful jötunn Gerðr, wife of the god Freyr, or these may be two separate figures who share the same name (see below and Gymir (father of Gerðr)).

One of Ægir's names, Hlér, is the namesake of the island Læsø (Old Norse Hlésey 'Hlér's island') and perhaps also Lejre in Denmark. Scholars have long analyzed Ægir's role in the Old Norse corpus, and the concept of the figure has had some influence in modern popular culture.
