Commodity branding has been characterized as the distinguishing cultural move of late capitalism and is widely viewed as a historically distinctive feature of the modern global economy. The brand’s rise to prominence following the Industrial Revolution and the attendant shift of corporate enterprise towards the dissemination of image based products have been further cited as contributing to the erosion of older forms of identity such as those based on kinship and class. However, comparisons between recent forms of branding and much earlier modes of commodity marking associated with the Urban Revolution of the fourth millennium BC suggest that systems of branding address a paradox common to all economies of scale and are therefore likely to arise (and to have arisen) under a wide range of ideological and institutional conditions, including those of sacred hierarchies and stratified states. An examination of the material and cognitive properties of sealing practices and the changing functions of seals in their transition from personal amulets to a means of labeling mass-produced goods helps to unpack the interlocking (pre)histories of quality control, authenticity, and ownership that make up the modern brand.
