Rome
before the Republic's end
Limen was the stone at the foot of a door, the threshold of a house and of a temple. It was sacred: a bride was carried over it so that her foot never touched the line between one life and the next. The word kept its work in the law: in limine, at the threshold, is still how a court says before anything else is decided.
Leipzig
1860
The first measurements of the threshold of sensation were published here. Science gave the threshold the Latin name limen, and everything beneath it a name of its own: subliminal, what the body registers before the mind does.

The anthropologist Arnold van Gennep found that every rite of passage, in every culture he could read, has the same three movements, separation, threshold and return, and named the middle one liminal. Victor Turner, sixty years later, called it betwixt and between: the state in which a person is no longer what they were and not yet what they will be.
Now
Liminal space is the name for the places built for passing through: the corridor, the stairwell, a shower at six in the morning. Empty on purpose. The Practice is made for them.
