 The publishing of "El Greco and His School" in 1962 had a huge impact in scholarly circles.In 1937 a highly influential study by art historian Rodolfo Pallucchini had the effect of greatly increasing the number of works accepted to be by Spanish Renaissance painter El Greco.Palluchini attributed to El Greco a small triptych in the Galleria Estense at Modena on the basis of a signature on the painting on the back of the central panel on the Modena triptych ("Χείρ Δομήνιχου", Created by the hand of Doménicos).
