The expression also appears to have been a favorite of German art historian Aby Warburg (1866--1929), though Warburg's biographer, E.M. Gombrich, is likewise uncertain if it originated with Warburg . An earlier form, "Le bon Dieu est dans le détail" ("the good God is in the detail") is generally attributed to Gustave Flaubert (1821--1880). Bartlett's Familiar Quotations lists the saying's author as anonymous . The phrase is attested in 1965; in 1969, it is referred to as an existing proverb . </P> <P> The phrase has several variants: (The / A) Devil (is) in the Detail (s). The original expression as, "God is in the detail" most likely had the expression ending with "detail" (without an "s"), colloquial usage often ends the idiom as "details"; where the word "detail" without an "s" can be used as both a singular and collective noun . However, the singular word "detail" has evolved to mean other terms in some cultures, such as a military security detail as a duty assignment, or detailing a car as cleaning or polishing a vehicle ("to detail"), and so the plural form, "details" has been used to more clearly indicate the finer points of a topic . </P>
