The iconography and composition of the Arcesilas Cup are widely acknowledged to have been modelled on weighing scenes found in Egyptian funerary art. However, less attention has been given to how the Arcesilas Painter came to experiment with a composition found in Egyptian funerary art, and why he would want to do so. This paper revises previous studies of the Arcesilas Cup's subject and its similarities to Egyptian illustrations of the weighing of the heart spell. Next, it explores how exchange and consumption in the sixth-century Mediterranean can be used to make sense of the cup's unique subject. Finally, it proposes contexts for the transmission of designs between Egyptian and Laconian artists.
