Detail of the feet of Andrea Doria as Neptune.
The entire sculpture is unfinished and was a commission from the grateful city-fathers of Genoa for expelling the French and reestablishing the republic under imperial protection. It seems there were two periods when Bandinelli worked on the piece in 1529 and in 1537-1538 before abandoning the project. The left hand dolphin is slight squashed and seems to have been squeezed into the composition.
