The facial type of Hercules in the present marble is related to Netherlandish sculpture of the late 17th and 18th centuries, in particular to the work of Artus Quellinus the Younger. The blind eyes, pursed lips and furrowed brow are remarkably close to a signed allegorical marble of Winter by Quellinus in the Rijksmuseum (Leeuwenberg and Halsema-Kubes, op.cit., pp. 252-253, fig. 338c) although the inclusion of the rocaille decoration here, would place it after the death of Quellinus himself, and may therefore indicate a younger Netherlandish artist such as Michiel Emanuel Shee, whose Two Groups of Two Naked Children at Play also display striking similarities to the present group.
