From Matthew Hargraves who is Chief Curator of Art Collections at the Yale Center for British Art:
"[I]t was the interest of his first wife, Mary Conover Mellon, whom he married in 1935, in thought and methods of Carl Jung that helped transform Paul Mellon into a major collector of Blake’s work.
Mary had introduced Paul Mellon to Jung’s ideas after they met in late 1933; even before marriage they had begun Jungian analysis in New York. In the early summer of 1938, Mr. and Mrs. Mellon journeyed to Switzerland and spent several weeks in Ascona above Lake Maggiore hoping the mountain air would relieve Mary’s chronic asthma. By coincidence Carl Jung was also in Ascona and the couple met the psychiatrist for the first time that summer. They returned the following year and saw Jung again before settling in Zurich in September 1939 to meet with Jung as patients several times a week. Germany’s invasion of Poland in 1939 meant this Swiss idyll could not last. In the spring of 1940 Mr. Mellon took a walking holiday with Jung but the obvious threat from Nazi Germany could not be ignored. He and Mary returned hastily to the United States shortly before the occupation of Denmark, Norway and France in May. By June 1941, feeling compelled to take action, Paul had enlisted in the US army; December saw the Japanese attack on Pearl Harbor and the United States enter the war.
While wartime service forced an end to the relationship with Jung, the year Paul Mellon enlisted was also the year he began to collect important works by Blake, an artist in whom Mr. Mellon found new interest through Jung’s exploration of the unconscious and his theories about collective archetypes. In 1941 he acquired some exceptional books. This included There is No Natural Religion (1794) [fig. 1], an “illuminated” book of eleven color-printed relief etchings with pithy text critiquing the reductive philosophical materialism of his day; a set of the engraved Illustrations to the Book of Job (1825) in its original binding; and a copy of Blake’s engravings illustrating Edward Young’s Night Thoughts (1797) , one of two copies believed to have been hand-colored by Blake himself.
At the same time that the Mellons were immersed in the worlds of Jung and Blake, Mary began to form a major collection of alchemical books and manuscripts inspired by Jung’s own collection of similar material. But the return to civilian life was soon clouded by tragedy. In October 1946 after Paul had been home only a year, Mary Mellon died suddenly from an asthma attack.
In the early 1950s Paul Mellon drifted away from Jungian influence and began almost a decade of Freudian analysis in Washington DC, a time he also got to know Anna Freud in London before becoming a significant supporter of her Foundation and what became the Anna Freud Centre for the psychiatric treatment of children. It was in 1953, as he was exploring Freudian psychology, that Paul Mellon bought his most important Blake book, Jerusalem The Emanation of the Giant Albion, a book that is at once Blake’s most difficult but also his greatest.

For Blake, Imagination was the world of real essences of which the visible world was merely a faint echo. He once argued that “This World of Imagination is the World of Eternity. . . . This World is Infinite & Eternal whereas the world of Generation or Vegetation is Finite & Temporal.” Paul Mellon’s interest in psychology is one reason why Blake held such a lifelong fascination given that Blake’s own life’s work was to free the Imaginative faculty from the forces of repression. Despite the incomprehension of his contemporaries and his poverty, Blake kept his devotion to spiritual and mental freedom alive until the day he died. This impulse has remained a vital force long after his death. And in his final months he explained to George Cumberland that his physical body might be 'feeble & tottering, but not in Spirit & Life, not in the Real Man The Imagination which Liveth for Ever.'"
