"Portraiture is by far the most important and productive genre of Egyptian art, just as biography is the most ancient and productive genre of Egyptian literature. Both genres are self-thematizations of an individual subject, one in the medium of art, the other in the medium of language. To be sure, the Egyptian portraits are not self-portraits in our sense of the term, nor are the biographical inscriptions autobiographies in our sense. It is not the self of an artist or writer which is revealed by a statue or speaking in an inscription, but the self of the patron, who had the portrait sculptured or the inscription carved. What matters is the “self” that gives the order, not the one that executes it....We can deal rather with the order-giving, self-thematizing self, which wants to convey these qualities in its iconic self-thematization. No one will deny that self-thematization prevails in the artistic and inscriptional evidence of Ancient Egypt to an extraordinary degree and that both genres of self-thematization account for the singular character of Egyptian culture. For underlying almost every Egyptian inscription and every monument there is such an “order-giving self.” Since, as has rightly and repeatedly been stressed, Egyptian art is always functional and never decorative, it is this notion of self which seems to determine its functional contexts to the greatest extent."
Is it possible that the Abrahamic text was ordered by Abraham and inscribed by somebody else? According to Assmann, this would be the norm.
