Isohemera bifrons·the Hinge of the Year

Hinge of the Year, the whole specimen
Plate XII. Isohemera bifrons, the whole specimen.

Day and night are equal only at the instant the year passes from one side to the other, so a balance can be a crossing that no one can stay in.

Balance is not a state but a crossing.

behavior Turns slowly to keep one half lit and one half dark, and holds level for a single moment twice a year.

provocation

What else in your life is balanced only at the moment it changes sides?

Each draw is the being derived afresh by the current laws at another seed (laws §11); the chosen one leads (where they sit in the morphospace).

I Dissection

Each organ answers one question about the idea. The framed one, its boundary, is the dominant organ: the being's class, the one the idea could not lose and stay itself.

Kernel of Equinox

Fig. 1. Kernel

Subsolar point

Which premise, if it were false, would kill this idea?

For one day the sun stands over the equator, and light and dark are shared equally across the whole earth.1

Boundary of Equinox

Terminator

❦ dominant organ

What sets it apart from what it is not, and how does it keep that distinction?

It is set apart from every other day by a line, the edge between day and night running from pole to pole; the day before and the day after already lean.1

Intake of Equinox

Fig. 3. Intake

Axial tilt

What must it feed on to work? What has to be present, noticed or supplied?

It feeds on the tilt of the earth and its path around the sun, and on someone watching where the sun rises against the horizon.4

Mechanism of Equinox

Fig. 4. Mechanism

Libra's scales

How does it turn what it takes in into what it gives out?

The tilted earth carries each half of the world from leaning toward the light to leaning away; the equinox is the instant the leaning changes sides.1

Output of Equinox

Fig. 5. Output

Vernal point

What does it make possible, visible or knowable?

It makes the year measurable, a fixed point from which seasons, calendars and the date of Easter are counted.2

drawn as: rays · view: detached

Dispersal of Equinox

Fig. 6. Dispersal

Light serpent

What part of it travels into other minds, ideas and fields, and by what vector?

It travels in festivals and aligned stones, Nowruz, Easter, the serpent of light that descends the steps at Chichén Itzá.4, 2

drawn as: meteor shower · view: in situ

Decay of Equinox

Fig. 7. Decay

Precession

What can it not digest, where does it fail, and what does it leave behind for others?

It cannot hold still against the stars; it slides slowly backward, the precession Hipparchus found, so every calendar built on it drifts and must be corrected.1, 3

Lineage

A founder, dissected by hand.

Offspring

Food web

  • feeds its output → the intake of Ritual
    Equinox gives a fixed point from which seasons and feasts are counted; Ritual needs a time set apart. The sky supplies the rite's time.
  • feeds the output of Memory → its intake
    Memory gives the stories a group tells about itself; Equinox feeds on someone watching the horizon, and only a group that remembers keeps watching.
  • friction its decay rubs against the boundary of Ritual
    The equinox drifts against the stars, while a rite holds to its fixed form; over centuries the feast and the season part.
