The traveller had begun to distrust doors.
Not because they were dangerous.
Because they were too easy.
A door suggested a simple world.
One side.
Another side.
An opening between them.
You stood here.
You went there.
Then you closed the door.
It was reassuring.
The city had taught her that reassurance was usually a warning.
So when she saw the door in the wall behind her, she did not turn around immediately.
She was walking along a street she had come to know well.
Or thought she knew.
It ran beside the river, past a row of old houses, then climbed towards the northern quarter.
She had walked it many times.
There had always been a blank wall on her left.
Now there was a door.
She kept walking.
Then stopped.
She looked back.
The door was still there.
It was a heavy wooden door, painted green.
She approached it slowly.
There was no handle.
No keyhole.
Only a small brass plate bearing a single word:
BEFORE
The traveller touched it.
The door opened.
She stepped through.
She found herself standing in the same street.
She turned around.
The door was gone.
The wall was blank.
She looked ahead.
The street was exactly as she remembered it.
Then she noticed something.
The houses were different.
Not greatly.
But enough.
The windows were smaller.
The road was narrower.
The river ran closer to the wall.
A tree stood where there had been a fountain.
She looked towards the north.
The tower was missing.
She knew the tower.
It had been there every day since she arrived.
She turned around.
There was no door.
She walked back along the street.
A shop stood where the bakery had been.
She stopped.
The sign above the door was unfamiliar.
She entered.
An old man was sitting behind the counter.
“Excuse me,” she said.
He looked up.
“Yes?”
“Where is the bakery?”
“What bakery?”
“The bakery on this street.”
“There has never been a bakery here.”
The traveller stared at him.
“Yes, there has.”
“No.”
“I have seen it.”
“Perhaps.”
“But it is there.”
The old man shook his head.
“Not here.”
She left.
Outside, the street seemed even stranger.
She continued walking.
The library was gone too.
The corridor was gone.
The courtyard was gone.
The two buildings had never been connected.
She stood in the middle of the street.
Her memory insisted that they had.
The city disagreed.
She hurried back towards the river.
The river was there.
The wall was there.
The door was not.
She touched the stone.
Nothing.
She knocked.
Nothing.
She stepped back.
A woman was walking towards her.
The traveller recognised her.
It was the woman who had shown her the room that wasn't there.
“You.”
The woman stopped.
“You look surprised.”
“Where am I?”
The woman smiled.
“You know where you are.”
“No. I mean—when am I?”
The woman looked at the wall.
“Before.”
“Before what?”
“Before the corridor.”
The traveller felt a sudden chill.
“So this is the city before?”
“Before some things.”
“But the buildings are different.”
“Yes.”
“The bakery isn't here.”
“No.”
“The library isn't here.”
“No.”
“The corridor doesn't exist.”
“No.”
The traveller looked towards the wall.
“But I remember them.”
“Of course.”
“Then how can they not have happened?”
The woman shrugged.
“They have.”
“Then this isn't the past.”
“What is it?”
The woman considered.
“A past.”
The traveller frowned.
“That's the same thing.”
“No.”
She began walking.
The traveller followed.
They came to a square.
A fountain stood in the centre.
The traveller recognised it.
It was the fountain that had been missing when she first entered the city.
She stopped.
“This is the fountain.”
“Yes.”
“It was here before.”
“Yes.”
“But I couldn't find it.”
“You couldn't find it then.”
“Why?”
The woman looked at her.
“Because you were looking for a city that had already changed.”
The traveller stood silently.
The woman continued walking.
“You thought the past was a place the present came from.”
“Isn't it?”
“Not quite.”
“Then what is it?”
“A history.”
“What is the difference?”
The woman stopped.
“Places are where things are.”
She pointed towards the fountain.
“Histories are how they became.”
The traveller looked at the water.
“But if the history has already happened, how can it change?”
The woman smiled.
“Can it?”
The traveller thought.
She remembered the bakery.
The library.
The corridor.
The rooms.
The doors.
She remembered the first door that had not been on the map.
She remembered the locked door.
She remembered the child saying that some things were “not yet”.
“What changed?” she asked.
“Your relation to it.”
“But that only changes what I know about the past.”
“Does it?”
The traveller hesitated.
The woman pointed towards the fountain.
“When you first arrived, you thought the city had always been this way.”
“Yes.”
“Then you discovered the fountain was missing.”
“Yes.”
“Later you learned that it had once been here.”
“Yes.”
“Now you are standing beside it.”
“Yes.”
“Is this the same fountain?”
The traveller looked at it.
“Yes.”
“But your city is different.”
She looked around.
The square seemed familiar and unfamiliar at once.
“The fountain has acquired a history,” she said.
The woman smiled.
“Exactly.”
The traveller understood.
Or thought she did.
The fountain itself had not travelled backwards in time.
Nothing supernatural had happened to it.
What had changed was the network of relations through which the fountain belonged to the city.
At first it had been an absence.
Then a mystery.
Then a remembered place.
Now it was part of a history she could recognise.
The object had not simply acquired new information.
It had acquired a different place in the becoming of the city.
She looked at the woman.
“Then the past is not fixed.”
“The past happened.”
“That isn't what I asked.”
“No.”
The woman smiled.
“The past is not fixed.”
They walked on.
The traveller began to notice other things.
A street that she had thought had always been there ended at a wall.
A house she remembered as old was still being built.
A bridge she had crossed every day did not yet exist.
And yet there was something else.
She knew where the bridge would be.
She knew that the street would eventually turn.
She knew that the house would one day have a red door.
She knew because she had already lived there.
The future seemed to be leaking backwards into the past.
She stopped.
“This is impossible.”
The woman looked at her.
“Why?”
“Because I know what will happen.”
“Do you?”
“Yes.”
“Then perhaps it already has.”
The traveller laughed.
“You make everything sound circular.”
“Only because you keep asking linear questions.”
They reached the edge of the square.
There was a door in a wall.
The traveller had not seen it before.
It was blue.
She recognised it immediately.
The locked door.
She approached it.
It had no keyhole now.
No inscription.
No lock.
She put her hand on it.
The door opened.
Beyond it was the street where she had first arrived.
She could see herself.
She was standing at the city gate.
She was holding the map.
She watched herself unfold it.
She watched herself walk towards the fountain.
She watched herself discover the passage.
The traveller stepped back.
She was looking at her own past.
Not remembering it.
Watching it.
She saw herself reach the courtyard.
She saw the first door appear.
She saw herself hesitate.
Then open it.
The scene continued.
The traveller stood perfectly still.
She had expected to see the past as something complete.
Instead she saw possibilities branching through it.
At one moment she remembered turning left.
But here, in the scene before her, she had not yet turned.
She could have gone right.
She could have stopped.
She could have left.
She could have done something else.
The past, while it was being lived, had been open.
Only afterwards had it become the past she remembered.
She suddenly understood something that frightened her.
The past had not always been inevitable.
It had become inevitable only from the position of the present.
She watched herself choose the left-hand street.
The scene closed.
The door remained open.
She looked at the woman.
“Did I change the past?”
“No.”
“Then what changed?”
“You did.”
The traveller looked through the door again.
She saw the street.
The choice.
The opening.
The city becoming what she remembered.
She realised that the past she carried with her was not a record of what had been waiting to happen.
It was the history of what had become.
And every new relation she entered changed what that history meant.
The door began to close.
She reached for it.
“Wait.”
The woman held her arm.
“Leave it.”
“But I want to see.”
“You already have.”
The door closed.
The wall became blank.
The traveller stood before it.
She turned around.
The square had changed.
The fountain was gone.
In its place stood a small tree.
She looked at the woman.
“What happened?”
“Nothing.”
“But the fountain.”
“It has a history.”
The traveller looked at the tree.
A leaf fell.
She picked it up.
For a moment she thought she heard the sound of water.
Then it was gone.
She began to walk.
Behind her, somewhere in the wall, a door opened.
She did not turn around.
For the first time, she understood that turning around would not necessarily take her back.
The past was not a room.
It was not a place behind a door.
It was the history of the doors through which the city had become what it was.
And history, she now suspected, was not what remained after becoming had finished.
It was one of the ways becoming continued.
