 Fernando Marias and Agustín Bustamante García, the scholars who transcribed El Greco's handwritten notes, connect the power that the painter gives to light with the ideas underlying Christian Neo-Platonism.Modern scholarly research emphasizes the importance of Toledo for the complete development of El Greco's mature style and stresses the painter's ability to adjust his style in accordance with his surroundings.Harold Wethey asserts that "although Greek by descent and Italian by artistic preparation, the artist became so immersed in the religious environment of Spain that he became the most vital visual representative of Spanish mysticism".
