 There was consensus that the triptych was indeed an early work of El Greco and, therefore, Pallucchini's publication became the yardstick for attributions to the artist.Nevertheless, Wethey denied that the Modena triptych had any connection at all with the artist and, in 1962, produced "El Greco and His School", a reactive catalogue "raisonné", with a greatly reduced corpus of materials.Whereas art historian José Camón Aznar had attributed between 787 and 829 paintings to the Cretan master, Wethey reduced the number to 285 authentic works and Halldor Sœhner, a German researcher of Spanish art, recognized only 137.
