=== Heracles ヘーラークレース ===[[Image:Herakles strangling snakes Louvre G192.jpg|thumb|[[Heracles]] strangling the snakes sent by Hera, [[Attica|Attic]] red-figured [[stamnos]], ca. 480–470 BCE. From [[Vulci]], [[Etruria]].]]
Hera is the stepmother and enemy of [[Heracles]]. The name Heracles means "Glory of Hera". In Homer's ''Iliad'', when Alcmene was about to give birth to Heracles, Zeus announced to all the gods that on that day a child by Zeus himself, would be born and rule all those around him. Hera, after requesting Zeus to swear an oath to that effect, descended from [[Mount Olympus|Olympus]] to [[Argos, Peloponnese|Argos]] and made the wife of [[Sthenelus (son of Andromeda and Perseus)|Sthenelus]] (son of Perseus) give birth to [[Eurystheus]] after only seven months, while at the same time preventing Alcmene from delivering Heracles. This resulted in the fulfillment of Zeus's oath in that it was Eurystheus rather than Heracles.<ref name="Hom. Il. 19.95"/> In [[Pausanias (geographer)|Pausanias']] recounting, Hera sent witches (as they were called by the Thebans) to hinder Alcmene's delivery of Heracles. The witches were successful in preventing the birth until [[Galanthis|Historis]], daughter of Tiresias, thought of a trick to deceive the witches. Like Galanthis, Historis announced that Alcmene had delivered her child; having been deceived, the witches went away, allowing Alcmene to give birth.<ref name="Paus. 9.11.3">[[Pausanias (geographer)|Pausanias]], ''Description of Greece'' [https://www.perseus.tufts.edu/hopper/text?doc=Paus.+9.11.3 9.11.3]</ref>
Hera's wrath against Zeus' son continues and while Heracles is still an infant, Hera sends two [[Serpent (symbolism)|serpents]] to kill him as he lies in his cot. Heracles throttles the snakes with his bare hands and is found by his nurse playing with their limp bodies as if they were a child's toy.<ref name=":2">{{Cite book|url=https://books.google.com/books?id=cZATs1x4BnsC&q=Galanthis+greek+mythology|title=Gods, Demigods and Demons: An Encyclopedia of Greek Mythology|last=Evslin|first=Bernard|date=2012-10-30|publisher=Open Road Media|isbn=9781453264386|language=en}}</ref>

One account of the origin of the [[Milky Way]] is that Zeus had tricked Hera into nursing the infant Heracles: discovering who he was, she pulled him from her breast, and a spurt of her milk formed the smear across the sky that can be seen to this day.<ref>{{cite journal|jstor=867195|title=The Origin of the Milky Way in the National Gallery|last1=Mandowsky|first1=Erna|journal=The Burlington Magazine for Connoisseurs|year=1938|volume=72|issue=419|pages=88–93}}</ref> Unlike any Greeks, the [[Etruscan civilization|Etruscan]]s instead pictured a full-grown bearded Heracles at Hera's breast: this may refer to his adoption by her when he became an Immortal. He had previously wounded her severely in the breast.
