アブズ(またはアプスー)は、ティアマトの間に長老神ラームとラハム(男性:「毛むくじゃら」)を産んだ。アンシャールとキシャールは地平線で合流し、アヌ(天)とキ(地)の親になると考えられていた。

Tiamat was the "shining" personification of the sea who roared and smote in the chaos of original creation. She and Apsu filled the cosmic abyss with the primeval waters. She is "'''Ummu-Hubur''' who formed all things".
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”).
