'Lahamu' was the first-born daughter of
Tiamat and
Apsu in
Akkadian mythology. With her brother
Lahmu she is the mother of
Anshar and
Kishar, who were in turn parents of the first gods. Lahamu is sometimes seen as a serpent, and sometimes as a woman with a red sash and six curls on her head. It is suggested that the pair were represented by the silt of the sea-bed.
She and her brother/husband are never mentioned separately.
'Lahamu in Literature'
In
China Miéville's
The Scar, it is briefly mentioned that there exists a large and undescribed sea creature called a lahamu.
