Both the subject and the form of this sculpture mark it as belonging to the neoclassical tradition, of which Canova was the first exponent within the medium. Its hermaic form was derived from Antiquity. Herms were male heads on marble plinths which were used as milestones to mark distances along roads. In the seventeenth century, this form came to be widely used in garden statuary. However, Canova did not just reuse an antique form but also added something new: he replaced the conventional male head with a female one, removed the plinth which functioned as a support, and integrated the head into the base, swathing the whole with a delicately sculpted mantle.
Today we can be sure that this version of the herm of the Vestal Tuccia is an authentic work by the neoclassical sculptor Antonio Canova, thanks to the archives held at Quantock Lodge, Bridgwater, a property that belonged to the great collector of classical art, Edward Arthur Vestey Stanley (Lord Taunton), who owned the Vestal Tuccia. Recent information, divulged by David Worthy, a historical researcher at Quantock Lodge, is enlightening: 'Sold by him [Canova] to Mr Webb of Langham Place, at whose sale I acquired it'. It has thus been proved, after heated discussions between experts in Canova’s work, that this is indeed the version produced for Frederick Webb in 1818, the first of a series of three that are currently known to exist.
