Eileithyia is the Greek goddess of childbirth and midwifery. Her Roman counterpart is Lucina.

Percy Jackson's Greek Gods

Eileithyia was born as the third child of Zeus and Hera. She became the Goddess of Childbirth.

After Leto got pregnant with Eileithyia's half-siblings, Artemis and Apollo, her mother Hera kidnapped Eileithyia to prevent the titaness from giving birth until the rest of the goddesses rescued her. After Artemis midwifed the birth of her own brother Apollo, Eileithyia came to share the same province of childbirth and midwifery with Eileithyia.

When Eileithyia arrived at Alcmene's house to help the princess deliver her half-sibling Heracles, her mother Hera forced Eileithyia to delay his birth until Eurystheus was born first instead, ensuring that Heracles wouldn't become King of Argos.


As a child of two Olympians (one of them is a member of the Big Three), Eileithyia is a very powerful goddess. She is considered a minor goddess.

  • Reproduction Manipulation: As the Goddess of Childbirth and Midwifery, Eileithyia has absolute control and divine authority over reproduction. As shown in Percy Jackson's Greek Heroes, she is able to freely alter and manipulate the process in which living organisms produce offspring. She delayed Alcmene's delivery of Heracles and accelerated Eurystheus's birth, though this affected the latter's health.


  • Eileithyia and Artemis share jurisdiction over childbirth and midwifery.
  • Her Egyptian equivalent is Tawaret.
