36 x 24 (91.5cm x 61.0cm) Oil on canvas board.
Right side of a triptic set on the Trevi Fountain at Rome.
The design of the trevi fountain is based on three architectural elements: a façade made of travertine; statues of carrara marble.
Neptune his carried on his tryumphal charriot by two horses jockeid by two Tritons. One horse is restless, one is calm. One triton is strong and young, one is older and holds a twisted shell that is using to announce their passage.
Ocean is also standing in the median portion of a tryumphal arch.
In the left part of the arch there is the statue of Abundance holding the horn of plenty. At her feet a toppled vase lies by a source of water. Above her there is a relief showing Agrippa commanding his generals to build the acqueduct.
