This sculpture was part of the S. Roque Fountain in Porto, demolished around 1875. It was located in the square of the same name, which also disappeared to make way for the opening of Rua Mouzinho da Silveira.
The sculpture represents a naked human figure, missing its head, with a sash across its body from the shoulder. It is sitting on the back of a dolphin, whose body is decorated with scales and with its lateral fins next to its head. Its mouth, partially mutilated, has an orifice through which water used to flow.
