This delightful work, in which I recognised Roubiliac's hand long before identifying the subject, must have been taken from the marble before it was mounted on its pedestal, as the position, with the head lower, and the admirably unobtrusive foot show. In the Trinity bust the drapery ends well above the pedestal and the head is raised, and any cast taken after 1756 would inevitably reproduce these features; the cast must therefore have been executed in Roubiliac's studio before the original went to Trinity. Although the surface is injured by varnish, the play of light and shade and the delicacy of the detail give the work an artistic value rare in a plaster cast and enhanced by the softened dignity of the pose.
