This chapter focuses on the individuals immortalized in the portrait panels in the new library of the Collège de Sorbonne. Built on a north-south axis, the long sides of the new library’s upper floor feature thirty-eight windows that not only provided necessary light but also serve as the library’s principal ornamentation. Twenty-five of the windows were embellished with portrait panels, presenting in each window an individual who had some ‘claim on the college's gratitude’. These individuals are Robert of Sorbon, William of Saint-Amour, Henry of Ghent, Godfrey [of Fontaines], Thomas of Ireland, Henry of Hesse, John of Pouilly, Peter Plaoul, John Luillier, Francis of Fon-tenay, Martin of Andocilia, John Noseret, Francis of Segovia, John of Pardo, John Jassa, John Quentin, John of La Rochelle, Gilbert Guérin, Peter Voleau, Dominic Beguin, Andrew of Château-Neuf, Gilles Boileau de Bouillon, John Charron, Gilbert Fournier, and John Standonck.
