Another characteristic of El Greco's mature style is the use of light. As Brown notes, "each figure seems to carry its own light within or reflects the light that emanates from an unseen source". 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. The later works of the painter turn this use of light into glowing colors. In "The Vision of Saint John" and the "Fifth Seal of the Apocalypse" the scenes owe their power to this otherworldly stormy light, which reveals their mystic character. The renowned "View of Toledo" (c. 1600) also acquires its visionary character because of this stormy light. The grey-blue clouds are split by lightning bolts, which vividly highlight the noble buildings of the city. His last landscape, "View and Plan of Toledo", is almost like a vision, all of the buildings painted glistening white. According to Wethey, in his surviving landscapes, "El Greco demonstrated his characteristic tendency to dramatize rather than to describe". Professor Nicos Hadjinicolaou notes the manner in which El Greco could adjust his style in accordance with his surroundings and stresses the importance of Toledo for the complete development of El Greco's mature style.
