Eki (also Ekhi, Eguzki, Iuski, Iguzki, Iduzki or Eguzku) are the names of the Sun in the Basque language.^[1] In Basque mythology, Eki or Eguzki is seen as a child of Mother Earth to whom they return daily.

They were regarded as the protector of humanity and the enemy of all evil spirits. The ancient Basques called her "grandmother" and held rites in her honour at sunset. They believed that when the sun set, Ekhi travelled into Itxasgorrieta ("The Reddish Seas") beneath the earth into the womb of Amalur or Lurbira, their mother.
