Nymph offering aniseed ball to prancing horse- # 315

In Twickenham, across the river from Richmond there is a grandiose fountain imported all the way from Italy in the 19th C by a wealthy fellow who appreciated art. This fountain is big, and this view is about 1/3 of it.

Actually it's quite a nice piece in its funny old way, if rather dated, and the town council recently spent a lot of money refurbishing it and fitting flood lights and new water pumps. What really amuses me is the nymph in the centre. Is she offering the horse an aniseed ball, or what?
