Babylonian myths were greatly influenced by the
Sumerian religion. Sometimes they were written on clay tablets inscribed with the
cuneiform script derived from
Sumerian cuneiform. The myths were usually either written in the
Sumerian or
Akkadian language. Some Babylonian texts were even translations into Akkadian from the Sumerian language of earlier texts, although the names of some deities were changed in Babylonian texts. Many Babylonian deities, myths, and religious writings are singular to that culture; for example, the uniquely Babylonian deity,
Marduk, replaced
Enlil as the head of the mythological pantheon. The
Enûma Eliš, a
creation myth epic was an original Babylonian work. In it,
Apsu and
Tiamat created "the elements of the world", but fought for various reasons, with Tiamat winning but being slaughtered along with her army by Marduk. Marduk became the first king within Tiamat's split body, which created the earth and sky, and founded Babylon. ==Religious festivals==
