Romulus, who along with his twin brother Remus is one of the central characters in Rome's foundation myth, celebrates his victory over King Acron of the Caeninenses by erecting a trophy made from the arms of the vanquished king.
This sketch is a modello designed by Rubens for a series of tapestries. Once the design was approved by his patron, Rubens' workshop would have created a full-sized cartoon to be sent to a specialized tapestry workshop. Working from the back of the tapestry, the weaver would have created a mirror image of the original design, thus accounting for Romulus’s sword being placed incorrectly on his right side in this sketch.
