It has been noted that the fact that in addition to Urash Anu could be paired with another earth deity, Ki, could sometimes lead to confusion, though ultimately the two were separate figures. It has been proposed that Anu paired with Ki represented heaven and earth as a unity prior to their cosmological separation, with Anu and Urash reflecting their later separated state instead. Another proposal is that Urash only represented the arable surface of earth, rather than its totality.
