Bulls for sacrifice, cows for work? Morphometric models suggest that female cattle were used for traction in the Chinese Bronze Age Late Shang dynasty (ca. 1300–1046 BCE)

Abstract

Training animals to pull agricultural equipment and wheeled transport significantly shaped and advanced human economic systems. In this context the use of large domestic animals such as cattle was a milestone event in human history, part of what Sherratt memorably termed the Secondary Products Revolution: the use of the products of live animals such as milk, wool and traction power. It is commonly assumed that male cattle were generally preferred for traction because of their greater strength compared with females, and the importance of the latter for breeding and, in some societies, for milk and for dairy products, but surprisingly little is known of this aspect of the Secondary Products Revolution in prehistoric China. Here we apply established morphometric models to 10 assemblages of cattle bones from Chinese Bronze Age (ca. 2000–221 BCE) contexts. Our results indicate a process of intensified cattle labour exploitation at this time and, intriguingly, we also observe the earliest labour employment of female cattle during the Late Shang dynasty (ca. 1300–1046 BCE). It is proposed that female cattle may have been required for traction because of the large numbers of male cattle, especially bulls, that were sent for ritual sacrifice. Such a strategy reveals a sophisticated social management, upon which the Late Shang civilisation eventually developed.
