Hexagram 49: Revolution (革) & Tzolkin
Hexagram 49 Revolution (革 gé) in I Ching and Tzolkin: Lake over Fire, the turning point of change. It maps to kins 193–196 — the close of one wavespell and the start of the next.
革 gé · Revolution
Revolution (革, gé) names the moment an old order loses its mandate and must give way to the new. Lake above and Fire below are elements naturally at odds — water smothers flame, flame boils water — and it is this friction that produces change. The judgment holds that a revolution becomes believable only “on its own day”: when the time is ripe, radical transformation is natural. The image charges the superior person with setting the calendar in order and marking the seasons anew — revolution resets the cycle itself.
In the Argüelles Codon system, hexagram 49 corresponds to kins 193–196 — themselves a turning point in the Tzolkin’s own structure. Kins 193–195 (Red Skywalker, White Wizard, Blue Eagle) carry tones 11–13 — Spectral, Crystal, Cosmic — the closing days of a wavespell. Kin 196 (Yellow Warrior) opens on tone 1, a wholly new wavespell: one tone-cycle ends and collides directly with the magnetic beginning of the next.
Both traditions read this point the same way: change is not a disruption of order but its inner mechanism — a cycle ends precisely so it can begin again. That is a structural resonance, not evidence of shared origin.
The Judgment
Revolution. On your own day you are believed. Supreme success, furthering through perseverance. When the time is ripe, radical change is natural and necessary.
The Image
Fire in the lake. The superior person sets the calendar in order and makes the seasons clear.
