At least in a general way, no. 48 should be associated with royal correspondence on the subject of, and rituals connected with, childbirth (cf. LAS 339+ with further references). It is interesting to note also the antecedent Middle Assyrian birth rituals and incantations where the cow of Sin is prominent.[[19]] Of no. 49 not enough is preserved for confidence even as to the general nature of the original text, but one could perhaps think that this is part of a composition in which the principal figure is Nabû. No. 50 is an excerpt from an otherwise unknown historical epic.
