Revising Friedlander. The "Underdrawing Connoisseurship" and the Master of the Turin Adoration

Friedländer proposed that the panels with the Scenes from the Lives of Saint Catherine and Saint Agnes(Genoa, Galleria di Palazzo Reale; Strasbourg, Musée des Beaux-arts) and the Adoration of the Magi (Turin, Galleria Sabauda) originally formed an altarpiece and attributed it to the conventional Master of the Turin Adoration. So far, and on the basis of traditional connois-seurship, Friedländer’s hypothesis has not been unani-mously accepted, the Genoese panels also suggested to have created the ad hoc Master of the Scenes from the Lives of Saint Agnes and Saint Catherine. The paper pre-sents the result of the IR examination conducted on the panels in Turin and Genoa. Applying a method of ‘under-drawing connoisseurship’, the paper discusses how, and to what extent, analogies in underdrawing might support Friedländer’s proposal or whether they must merely be regarded as proof that the panels were executed in the same workshop.
