Horn Turns an Axinite Crystal Toward the Light

Morning is quiet enough for the notebook to stay blank a little longer.

By the window, Horn turns a small axinite crystal between finger and thumb. Brown, then violet. Blue arrives at an angle almost missed. Another turn loses it.

Its little axe edge suggests a tool waiting for a handle. Horn, accustomed to shaping boards, keeps a gentler grip. No work for this blade today.

Inside is a triclinic lattice: unequal axes, oblique angles, an order that owes nothing to a neat square. The changing colours are not three stones taking turns. They are one stone answering light differently along different directions.

Horn thinks of the energy bound into that structure—not a secret fuel to uncork, but matter holding its arrangement while light finds a way through.

In the notebook, at last: Before calling something brown, turn it.
