… in Order for the making of a Busto of him to be placed in the said College (Fig. 9).17 The two busts of Ray and Willoughby illus- trate well how Roubiliac could use a variety of earlier visual sources and then create a likeness of an historical figure that has all the immediacy and animation of an ad vivum portrait. That of Willoughby seems to have been based on a late seventeenth-century portrait (probably made ac- cessible to Roubiliac by the sitter’s descendants), which shows him holding a book.18 The painted source is, however, enlivened by the treatment of the hair and collar so as to suggest that they are caught by a breeze from the sitter’s right hand side, to which Willoughby turns his head. Ray’s image is rather more static. The lower part of this bust in fact replicates a pattern used for a con- temporary figure: Jonathan Tyers, the proprietor of Vauxhall Gardens and very much still living (Fig. 10).19 The introduction of the collar and the chiselling of the inner side of the drapery envel- oping the bust – a feature introduced in the mar- ble version but not yet present on the model – means that there is no disparity between bust and head. In this case, the head is based on the portrait (then in the British Museum) but, here Fig. 6: Interior of the Wren Library with busts of Francis Bacon and Sir Isaac Newton at the far end, Trinity College, Cam- bridge, 1815, aquatint.
