In his introduction John Ashbery calls the book "the finest work of Surrealist fiction," noting that de Chirico "invented for the occasion a new style and a new kind of novel . . . his long run-on sentences, stitched together with semi-colons, allow a cinematic freedom o f narration . . . his language, like his painting, is invisible: a transparent but dense medium containing objects that are more real than reality." Hebdomeros is accompanied by an appendix of previously untranslated or uncollected writings, including M. Dudron's Adventure, a second, fragmentary novel translated by John Ashbery.

    Isolated and secure, the residents lack nothing, yet one day, a doctor at the clinic goes on a suicidal shooting spree. Dr. Jane Sinclair is hired as his replacement, and her husband Paul uncovers the dangerous psychological vents that maintain Eden-Olympia's smoothly-running surface.
