PEGOMANCY — [Noun] Divination by interpreting the appearance or behavior of fountains or springs. From the Ancient Greek πηγή (pēgḗ, "fountain, spring") + -mancy ("divination"). Unlike "hydromancy" (which casts a wide net over all watery auguries) or "lecanomancy" (which confines itself to the artifice of bowls), pegomancy is the art of reading nature’s own liquid script. It is the sudden clarity of a spring running cloudy with silt, the way bubbles rise in a pattern like cuneiform, or the eerie stillness of a sacred well that refuses to ripple even when stones are dropped—proof that the earth, too, has its moods and warnings, if only we knew how to listen.
