Erwin Panofsky's Habilitation thesis, which was previously believed lost and was discovered quite by surprise in June 2012 at the Zentralinstitut für Kunstgeschichte in Munich, was published by De Gruyter in 2014. The work, titled Die Gestaltungsprincipien Michelangelos, besonders in ihrem Verhältnis zu denen Raffaels, was never published, and may well be regarded as a milestone in the academic history of the field of art history. The epochal work is edited by Gerda Panofsky. De Gruyter publishes it accompanied by Gerda Panofsky’s own biography about her late husband’s early life, school, and student years, along with his conceptual sketches from the years 1915–17 that have been preserved in manuscript form.
