This stone group is related, stylistically, to sculpture of the late 14th and early fifteenth centuries in central and southern France. In particular, one can compare the stylised hair and beard of St. James to several alabaster figures from the tomb of the cardinal Philippe Cabassole, thought to have been executed by the workshop of Barthélemy Cavalier in the 1370's (Paris, op. cit., no. 72). Similarly, the drapery style is reminiscent of the drapery executed on a kneeling figure of Charles VI, also originating in the area of Avignon (Paris, op. cit., no. 100).
The attribution to southern France is further supported by the strong ties which the region had to the pilgrimage site of Santiago de Compostela, and the fact that St. James is holding an ivory, siculo-arabic casket.
