Known primarily to literary historians as the longtime companion of
poet James Merrill, Jackson also produced, though never published, a
wealth of ms. material himself, including poems, stories, and novels.
However, his greatest claim-to-fame as a writer is a most enigmatic one.
Together with Merrill, Jackson helped to “write” the
epic Changing Light of Sandover (1982) with
the aid of a Ouija Board. Though Merrill is most often singly credited
with writing Sandover, Jackson’s own role in the process of composition
makes such a facile designation problematic.
