Focus on this artwork and discuss the Commissioning.
Bernini had already been commissioned by Cardinal Montalto to create the Neptune and Triton fountain for his gardens at the Villa Montalto on the outskirts of Rome, and was involved in the commissioning of the David statue that eventually ended up in the Villa Borghese. But the precise reason behind this bust is unclear; given that Cardinal Montalto died in 1623, it has been suggested the bust was created as part of a funerary tomb. However, Montalto may well himself have commissioned the bust prior to his death.
