=== Challenges to Power 権力への挑戦 === [[File:Zeus contra Poryphion Pergamonaltar.JPG|thumb|upright=1.5|Zeus (centre-left) battles against Porphyrion (far-right), detail of the Gigantomachy frieze from the [[Pergamon Altar]], [[Pergamon Museum]], [[Berlin]].]]
Upon assuming his place as king of the cosmos, Zeus' rule is quickly challenged. The first of these challenges to his power comes from the [[Giants (Greek mythology)|Giants]], who fight the Olympian gods in a battle known as the Gigantomachy. According to Hesiod, the Giants are the offspring of Gaia, born from the drops of blood that fell on the ground when Cronus castrated his father Uranus;<ref>Hard 2004, [https://books.google.com/books?id=r1Y3xZWVlnIC&pg=PA86 p. 86]; [[Hesiod]], ''[[Theogony]]'' [http://data.perseus.org/citations/urn:cts:greekLit:tlg0020.tlg001.perseus-eng1:173-206 183–7].</ref> there is, however, no mention of a battle between the gods and the Giants in the ''Theogony''.<ref>Hard 2004, [https://books.google.com/books?id=r1Y3xZWVlnIC&pg=PA86 p. 86]; Gantz, p. 446.</ref> It is Apollodorus who provides the most complete account of the Gigantomachy. He says that Gaia, out of anger at how Zeus had imprisoned her children, the Titans, bore the Giants to Uranus.<ref>Gantz, p. 449; Hard 2004, [https://books.google.com/books?id=r1Y3xZWVlnIC&pg=PA90 p. 90]; [[Bibliotheca (Pseudo-Apollodorus)|Apollodorus]], [http://data.perseus.org/citations/urn:cts:greekLit:tlg0548.tlg001.perseus-eng1:1.6.1 1.6.1].</ref> There comes to the gods a prophecy that the Giants cannot be defeated by the gods on their own, but can be defeated only with the help of a mortal; Gaia, upon hearing of this, seeks a special ''pharmakon'' (herb) that will prevent the Giants from being killed. Zeus, however, orders [[Eos]] (Dawn), [[Selene]] (Moon) and [[Helios]] (Sun) to stop shining, and harvests all of the herb himself, before having [[Athena]] summon [[Heracles]].<ref>Hard 2004, [https://books.google.com/books?id=r1Y3xZWVlnIC&pg=PA89 p. 89]; Gantz, p. 449; [[Bibliotheca (Pseudo-Apollodorus)|Apollodorus]], [http://data.perseus.org/citations/urn:cts:greekLit:tlg0548.tlg001.perseus-eng1:1.6.1 1.6.1].</ref> In the conflict, [[Porphyrion]], one of the most powerful of the Giants, launches an attack upon Heracles and Hera; Zeus, however, causes Porphyrion to become lustful for Hera, and when he is just about to violate her, Zeus strikes him with his thunderbolt, before Heracles deals the fatal blow with an arrow.<ref>Hard 2004, [https://books.google.com/books?id=r1Y3xZWVlnIC&pg=PA89 p. 89]; Gantz, p. 449; Salowey, p. 236; [[Bibliotheca (Pseudo-Apollodorus)|Apollodorus]], [http://data.perseus.org/citations/urn:cts:greekLit:tlg0548.tlg001.perseus-eng1:1.6.2 1.6.2]. Compare with [[Pindar]], ''Pythian'' [http://data.perseus.org/citations/urn:cts:greekLit:tlg0033.tlg002.perseus-eng1:8 8.12–8], who instead says that Porphyrion is killed by an arrow from [[Apollo]].</ref>
