Workshop of Frans Floris, possibly the young Frans Pourbus the Elder

This figure compares closely to the kneeling Magdalene in the central panel of the Triptych of the Penitent Sinners (Church of Saint Léonard in Zoutleeuw), painted in the second half of the 1560s by Frans Floris and his workshop.¹  It is possible that the present panel was made in Frans Floris' workshop, and the handling and coloration seems to recall that of the young Frans Pourbus the Elder, who was in Floris' studio by 1564.
