=== 権力への昇級 ===
『テオゴニア』によれば、ゼウスが成人した後、クロノスは「ガイアの策略によって、しかしゼウスの技術と力によって」5人の子供と石を吐き出す<ref>Gantz, p. 44; Hard 2004, [https://books.google.com/books?id=r1Y3xZWVlnIC&pg=PA68 p. 68]; Hesiod, ''Theogony'' [http://data.perseus.org/citations/urn:cts:greekLit:tlg0020.tlg001.perseus-eng1:492-506 492–7].</ref>。おそらく、最初に石を吐き出し、次に5人の子供たちをそれぞれ飲み込むのと逆の順序で吐き出したと思われる。そしてゼウスは、この石をデルフォイに設置し、「以後、人間へのしるしと驚異として」機能するようにした<ref>Hard 2004, [https://books.google.com/books?id=r1Y3xZWVlnIC&pg=PA68 p. 68]; Hesiod, ''Theogony'' [http://data.perseus.org/citations/urn:cts:greekLit:tlg0020.tlg001.perseus-eng1:492-506 498–500].</ref>。ゼウスは次にキュクロプスを解放し、そのお礼にガイアが隠していた雷鳴をゼウスに渡す<ref>Hard 2004, [https://books.google.com/books?id=r1Y3xZWVlnIC&pg=PA68 p. 68]; Gantz, p. 44; Hesiod, ''Theogony'' [http://data.perseus.org/citations/urn:cts:greekLit:tlg0020.tlg001.perseus-eng1:492-506 501–6]. The Cyclopes presumably remained trapped below the earth since being put there by Uranus (Hard 2004, [https://books.google.com/books?id=r1Y3xZWVlnIC&pg=PA68 p. 68]).</ref>。そして、ゼウス率いるオリンピアンとクロノス率いるティターンが宇宙の支配権をめぐって争う「ティタノマキアー」が始まり、ゼウスとオリンピアンはオリンポス山から、ティターンはオトリス山から戦っている<ref>Hard 2004, [https://books.google.com/books?id=r1Y3xZWVlnIC&pg=PA68 p. 68]; Gantz, p. 45; Hesiod, ''Theogony'' [http://data.perseus.org/citations/urn:cts:greekLit:tlg0020.tlg001.perseus-eng1:617-653 630–4].</ref>。戦いは10年間続き、明確な勝者は現れなかったが、ガイアの助言により、ゼウスはキュクロプス同様地中に幽閉されていた百人隊を解放する<ref>Hard 2004, [https://books.google.com/books?id=r1Y3xZWVlnIC&pg=PA68 p. 68]; Hesiod, ''Theogony'' [http://data.perseus.org/citations/urn:cts:greekLit:tlg0020.tlg001.perseus-eng1:617-653 624–9], [http://data.perseus.org/citations/urn:cts:greekLit:tlg0020.tlg001.perseus-eng1:617-653 635–8]. As Gantz, p. 45 notes, the ''Theogony'' is ambiguous as to whether the Hundred-Handers were freed before the war or only during its tenth year.</ref>。
According to the ''Theogony'', after Zeus reaches manhood, Cronus is made to disgorge the five children and the stone "by the stratagems of Gaia, but also by the skills and strength of Zeus", presumably in reverse order, vomiting out the stone first, then each of the five children in the opposite order to swallowing. Zeus then sets up the stone at [[Delphi]], so that it may act as "a sign thenceforth and a marvel to mortal men". Zeus next frees the [[Cyclopes]], who, in return, and out of gratitude, give him his thunderbolt, which had previously been hidden by Gaia. Then begins the [[Titanomachy]], the war between the Olympians, led by Zeus, and the Titans, led by Cronus, for control of the universe, with Zeus and the Olympians fighting from [[Mount Olympus]], and the Titans fighting from [[Mount Othrys]]. The battle lasts for ten years with no clear victor emerging, until, upon Gaia's advice, Zeus releases the [[Hundred-Handers]], who (similarly to the Cyclopes) were imprisoned beneath the Earth's surface.<ref>Hard 2004, [https://books.google.com/books?id=r1Y3xZWVlnIC&pg=PA68 p. 68]; [[Hesiod]], ''[[Theogony]]'' [http://data.perseus.org/citations/urn:cts:greekLit:tlg0020.tlg001.perseus-eng1:617-653 624–9], [http://data.perseus.org/citations/urn:cts:greekLit:tlg0020.tlg001.perseus-eng1:617-653 635–8]. As Gantz, p. 45 notes, the ''Theogony'' is ambiguous as to whether the Hundred-Handers were freed before the war or only during its tenth year.</ref> He gives them nectar and ambrosia and revives their spirits,<ref>[[Hesiod]], ''[[Theogony]]'' [http://data.perseus.org/citations/urn:cts:greekLit:tlg0020.tlg001.perseus-eng1:617-653 639–53].</ref> and they agree to aid him in the war.<ref>[[Hesiod]], ''[[Theogony]]'' [http://data.perseus.org/citations/urn:cts:greekLit:tlg0020.tlg001.perseus-eng1:654-686 654–63].</ref> Zeus then launches his final attack on the Titans, hurling bolts of lightning upon them while the Hundred-Handers attack with barrages of rocks, and the Titans are finally defeated, with Zeus banishing them to Tartarus and assigning the Hundred-Handers the task of acting as their warders.<ref>[[Hesiod]], ''[[Theogony]]'' [http://data.perseus.org/citations/urn:cts:greekLit:tlg0020.tlg001.perseus-eng1:687-728 687–735].</ref>
Apollodorus provides a similar account, saying that, when Zeus reaches adulthood, he enlists the help of the Oceanid [[Metis (mythology)|Metis]], who gives Cronus an emetic, forcing to him to disgorge the stone and Zeus's five siblings.<ref>Hard 2004, [https://books.google.com/books?id=r1Y3xZWVlnIC&pg=PA69 p. 69]; Gantz, p. 44; [[Bibliotheca (Pseudo-Apollodorus)|Apollodorus]], [http://data.perseus.org/citations/urn:cts:greekLit:tlg0548.tlg001.perseus-eng1:1.2.1 1.2.1].</ref> Zeus then fights a similar ten-year war against the Titans, until, upon the prophesying of Gaia, he releases the Cyclopes and Hundred-Handers from Tartarus, first slaying their warder, [[Campe]].<ref>Hard 2004, [https://books.google.com/books?id=r1Y3xZWVlnIC&pg=PA69 p. 69]; [[Bibliotheca (Pseudo-Apollodorus)|Apollodorus]], [http://data.perseus.org/citations/urn:cts:greekLit:tlg0548.tlg001.perseus-eng1:1.2.1 1.2.1].</ref> The Cyclopes give him his thunderbolt, Poseidon his trident and Hades his helmet of invisibility, and the Titans are defeated and the Hundred-Handers made their guards.<ref>Hard 2004, [https://books.google.com/books?id=r1Y3xZWVlnIC&pg=PA69 p. 69]; [[Bibliotheca (Pseudo-Apollodorus)|Apollodorus]], [http://data.perseus.org/citations/urn:cts:greekLit:tlg0548.tlg001.perseus-eng1:1.2.1 1.2.1].</ref>
