Depictions of tilling and weaving were an important means for sponsors, particularly rulers, to demonstrate their interest in the welfare of the people. To my knowledge, there has never been a serious study of the origins of this tradition and the political implications of these images and accompanying texts. In this fascinating study, Hammers does a worthy and extremely valuable job of elucidating the beginnings of the visual and textual traditions. -- Maxwell K.
