The Spinario of the Galleria Estense is one of the best known examples of a sculptural typology depicting a young man sitting on a rock intent on removing a thorn from the sole of his left foot. Derived from Hellenistic models, the subject enjoyed immense fortune during the Renaissance, especially from the donation of the Lateran bronzes by Sixtus IV (141-1484) in 1471, when the Spinario in bronze currently kept at the Capitoline Museums it became one of the most studied and appreciated works of the antiquarian culture of the time. The work became part of the Este collections through Cardinal Ippolito II d'Este (1509-1572). On the death of the cardinal he appears in the inventories of the duke Alfonso II (1533-1597) and in the late sixteenth century he remembers the restoration commissioned by the duke Cesare d’Este (1562-1628) to the Ferrarese sculptor Francesco Casella.
