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.
Kui kunstiajaloolane José Camón Aznar pidas El Greco omaks 787–829 maali, siis Wethey vähendas selle arvu 285 autentse tööni ning sakslasest hispaania kunsti uurija Halldor Sœhner omistas kreeta meistrile vaid 137 tööd.
