Celebrating the fourth centenary of the death of El Greco (c.1541-1614), this volume analyzes the state of scholarly research on the artist. The Companion is carefully conceived to represent international perspectives on El Greco, who lived in different lands and, in modern times, has drawn critical acclaim from beyond the borders of his homelands. Contributors identify scholars and publications that have shaped the current understanding of El Greco, including his status as an artist, the stages of his career, his working methods, different categories of artworks, patronage, collecting, and his posthumous critical fortunes. The authors review traditional and innovative lines of inquiry, identifying primary or secondary resources available to researchers, while also suggesting directions for future projects.
