The present bronze is related to a statuette on the same scale in the Abbott Guggenheim Collection (Camins, loc. cit.). That example includes the figure's outstretched arms and a lionskin, and makes it clear that he was originally shown holding the globe of the world.
The Abbott Guggenheim example has been associated with the circle of Adriaen de Vries, although it has also been suggested that the figure may have more to do with the circle of Pierre Puget.
