BRONTOMANCY — [Noun] The practice of divining the future or interpreting omens by the sound or occurrence of thunder. From the Ancient Greek βροντή (brontḗ, "thunder") and μαντεία (manteía, "prophecy"). Unlike "astrapomancy" (which reads lightning’s jagged script) or "ceraunoscopy" (which deciphers the fall of thunderbolts), brontomancy listens to the sky’s deep, rolling voice. It is the low growl of distant storm clouds, the sudden crack that splits the horizon, the prolonged rumble that lingers like a warning—the ancient art of hearing the divine in what we now dismiss as mere weather.
