楔形文字に記録された神話では、エンキ(後のエア)が、アプスーが若い神々を殺害しようと企て、その騒々しさに腹を立てていると正しく信じ、彼を捕らえて自分の神殿E-Abzu(「アブスの神殿」)の下に閉じ込めたとされる。これを怒った息子のキングはティアマトに報告し、ティアマトはアプスの仇を討つために11体の怪物を作り、神々と戦わせた。 以下は、ティアマト自身の子孫である。バスム(Bašmu、毒蛇)、ウシュムガル(Ušumgallu、大龍)、ムシュマッヘ(Mušmaḫ、高貴な蛇)、ムシュフシュ(Mušḫuššu、猛烈な蛇)、ラフム(Laḫmu、毛深い者)、ウガル(Ugallu、大天候の獣)、ウリディンム(Uridimmu、狂気のライオン)、ギルタブルル(Girtablullû、サソリ男)、ウム・ダブルツ(Umū dabrūtu、「激しい嵐」)、クルル(Kululû、「魚男」)、クサリック(Kusarikku、「牛男」)。
ティアマトは「運命の石版」を持っており、原初の戦いで、自分の恋人であり、軍団のリーダーとして選んだ神であり、自分の子供の一人でもあるキングにそれを与えたのである。
In the myth recorded on [[Cuneiform|cuneiform tablets]], the deity [[Enki]] (later Ea) believed correctly that Apsu was planning to murder the younger deities, upset with the noisy tumult they created, and so captured him and held him prisoner beneath his temple, the [[É (temple)|E-Abzu]] ("temple of Abzu"). This angered [[Kingu]], their son, who reported the event to Tiamat, whereupon she fashioned eleven monsters to battle the deities in order to avenge Apsu's death. These were her own offspring: [[Bašmu]] (“Venomous Snake”), [[Ušumgallu]] (“Great Dragon”), [[Mušmaḫḫū]] (“Exalted Serpent”), [[Mušḫuššu]] (“Furious Snake”), [[Lahmu|Laḫmu]] (the “Hairy One”), [[Ugallu]] (the “Big Weather-Beast”), [[Uridimmu]] (“Mad Lion”), [[Girtablilu|Girtablullû]] (“Scorpion-Man"), [[Umū dabrūtu]] (“Violent Storms"), [[Kulullû]] (“Fish-Man") and [[Kusarikku]] (“Bull-Man”).
Tiamat possessed the [[Tablet of Destinies (mythic item)|Tablet of Destinies]] and in the primordial battle she gave them to Kingu, the deity she had chosen as her lover and the leader of her host, and who was also one of her children. The terrified deities were rescued by Anu, who secured their promise to revere him as "[[king of the gods]]". He fought Tiamat with the arrows of the winds, a net, a club, and an invincible spear. Anu was later replaced by [[Enlil]] and, in the late version that has survived after the [[First Babylonian dynasty|First Dynasty]] of [[Babylon]], by [[Marduk]], the son of Ea.
