ヘーラーはレートーの妊娠と父親がゼウスであることを知ると、自然霊を説得して、レートーがテラファーム、本土、海上の島、太陽の下のどの場所でも出産できないようにした<ref>Gaius Julius Hyginus, ''Fabulae'' 140).</ref>。ポセイドーンがレートーを憐れみ、本土でもない本物の島でもない浮島デロス島に導き、そこでレートーは子供を産むことができた<ref>Hammond.

When Hera discovered that [[Leto]] was pregnant and that Zeus was the father, she convinced the nature spirits to prevent Leto from giving birth on [[Solid earth|terra-firma]], the mainland, any island at sea, or any place under the sun. Poseidon gave pity to Leto and guided her to the floating island of [[Delos]], which was neither mainland nor a real island where Leto was able to give birth to her children. Afterwards, Zeus secured Delos to the bottom of the ocean. The island later became sacred to Apollo. Alternatively, Hera kidnapped [[Eileithyia]], the goddess of childbirth, to prevent Leto from going into labor. The other gods bribed Hera with a beautiful necklace nobody could resist and she finally gave in.<ref name=":4">{{cite journal|jstor=639206|title=Pindar on the Birth of Apollo|last1=Rutherford|first1=Ian|journal=The Classical Quarterly|year=1988|volume=38|issue=1|pages=65–75|doi=10.1017/S000983880003127X|s2cid=170272842}}</ref>
Either way, Artemis was born first and then assisted with the birth of Apollo.<ref>Pseudo-Apollodorus, ''Bibliotheke'' 1.4.1; [[Antoninus Liberalis]], ''Metamorphoses'', 35, giving as his sources Menecrates of Xanthos (4th century BCE) and Nicander of Colophon; [[Ovid]], ''[[Metamorphoses]]'' vi.317-81 provides another late literary source.</ref> Some versions say Artemis helped her mother give birth to Apollo for nine days.<ref name=":4" /> Another variation states that Artemis was born one day before Apollo, on the island of [[Ortygia]] and that she helped Leto cross the sea to Delos the next day to give birth to Apollo.
