Pietro da Cortona
After Margaret Thatcher had exposed Blunt's espionage, he continued his art history work by writing and publishing a "Guide to Baroque Rome" (1982). He intended to write a monograph about the architecture of Pietro da Cortona but he died before realising the project. His manuscripts were sent to the intended co-author of this work, German art historian Jörg Martin Merz by the executors of his will. Merz published a book, "Pietro da Cortona and Roman Baroque Architecture" in 2008 incorporating a draft by the late Anthony Blunt.
