An actor's obituary in The New York Times today suggests
a review of the phrase "geometry and death" in this journal.
In that review, the phrase, by J. G. Ballard in a 2006 article,
refers to German fortifications in World War II. Ballard had
earlier used the same phrase in connection with French
nuclear-test structures in the Pacific —
— From Rushing to Paradise by J. G. Ballard, 1994.
Those interested in the religious meaning of the phrase "Saint-Esprit"
may consult this journal on the date of Ballard's death.
