『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ヘカトンケイルを解放する<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>。ゼウスはネクタルとアンブロシアを与えて彼らの精神を蘇らせ<ref>Hesiod, ''Theogony'' [http://data.perseus.org/citations/urn:cts:greekLit:tlg0020.tlg001.perseus-eng1:617-653 639–53].</ref>、彼らは戦争で彼に協力することを承諾する<ref>Hesiod, ''Theogony'' [http://data.perseus.org/citations/urn:cts:greekLit:tlg0020.tlg001.perseus-eng1:654-686 654–63].</ref><ref group="私注">おそらく「[[不老不死の薬]]」とは、死んだ者を生き返らせることができる、と考えられていたのではないだろうか。</ref>。ゼウスはティターンに稲妻を浴びせ、へカントケイルは岩を投げて攻撃し、ティターンはついに倒され、ゼウスはティターンをタルタロスへ追放し、へカントケイルはその監視役を命じられた<ref>Hesiod, ''Theogony'' [http://data.perseus.org/citations/urn:cts:greekLit:tlg0020.tlg001.perseus-eng1:687-728 687–735].</ref><ref group="私注">ヘカントケイルとは、中国神話の共工や[[相柳]]に相当するのではないだろうか。</ref>。
アポロドロスも同様の説明をしており、ゼウスが大人になったとき、オセアニア人のメーティスの助けを借りて、クロノスに嘔吐物を与え、石とゼウスの5人の兄弟を吐き出させたと述べている<ref>Hard 2004, [https://books.google.com/books?id=r1Y3xZWVlnIC&pg=PA69 p. 69]; Gantz, p. 44; Apollodorus, [http://data.perseus.org/citations/urn:cts:greekLit:tlg0548.tlg001.perseus-eng1:1.2.1 1.2.1].</ref>。その後、ゼウスはティターンと10年戦争を続けるが、ガイアの予言により、キュクロプスとへカントケイルをタルタロスから解放し、まず彼らの監視役であるカンペを殺害した<ref>Hard 2004, [https://books.google.com/books?id=r1Y3xZWVlnIC&pg=PA69 p. 69]; Apollodorus, [http://data.perseus.org/citations/urn:cts:greekLit:tlg0548.tlg001.perseus-eng1:1.2.1 1.2.1].</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. 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>
According to the ''[[Iliad]]'', after the battle with the Titans, Zeus shares the world with his brothers, Poseidon and Hades, by drawing lots: Zeus receives the sky, Poseidon the sea, and Hades the underworld, with the earth and Olympus remaining common ground.<ref>Gantz, p. 48; Hard 2004, [https://books.google.com/books?id=r1Y3xZWVlnIC&pg=PA76 p. 76]; ''[[Brill's New Pauly]]'', [https://referenceworks.brillonline.com/entries/brill-s-new-pauly/zeus-e12216820 s.v.
