These panels, probably complementary elements of a non-identified or lost altarpiece, show the one King David and sibyls Cumea and Helespontida and the other prophet Jeremiah and sibyls Phrigia and Erithrea. All six figures bear phylacteria with texts alluding to the Passion of Christ. From the end of the Middle Ages, the humanistic culture dominant in Western Europe boosted the recuperation of subjects from classical Antiquity. Thus, the Sibyls, ancient Greco-Roman prophetesses, were associated to the Prophets of Ancient Testament as personages who misteriously predicted among pagans the Incarnation and Salvation of Christ. Altohugh Chandler R. Post attributed these panels to Perot Gascó, authors like Rafael Cornudella have stated that the noteworthy Romanism of these figures is rather far from the normal atmosphere of gasconian works. Stylistical comparisons allow an attribution to Pere Serafí, so-called lo Grec, a painter and poet of Italian or maybe Cypriot origin, one of the most interesting personages of Catalan painting in 16th century, among other reasons due to his advanced aesthetic options. Though the precise history of these objects is unknown -apart from their presence in the MEV from its origins-, it is known that Pere Serafí was in Vic in 1544 painting the Cathedral organ's opening panels.
