"Tae-ung-a."

"Hm?"

"Wait a second."

Choi Harin called to me.

She had been studying the screen closely until a moment ago, and now she got up from her seat. The way she was looking at the painting had changed.

"Can you ask them to zoom in on that painting a little?"

"Where?"

"Upper right. The part with the bell tower."

"Please zoom in on the upper right."

I made the request toward the dais. She spoke fluent English too.

But right now, it apparently hadn't even occurred to her to ask herself.

She was that focused. The screen zoomed in.

A small village appeared beneath a golden sky. Beyond it rose a single pointed church bell tower.

"That painting?"

"No. A copperplate engraving made later, based on the original."

She didn't take her eyes off the screen.

"Our foundation had a reproduction of that engraving."

"And you remember it?"

"My grandfather compared it with the records of the original for me. He had me guess why the same landscape faced the other way."

My eyes went back to the screen.

"So left and right got flipped when the engraving was printed?"

"That edition, yes. The composition cut into the copper plate came out reversed when it was printed on paper."

She touched the spot below the bell tower.

"It's not just the bell tower. The way the river bends and even the layout of the buildings match."

"The engraving, not the original?"

"Yeah."

Only then did I understand what she meant. The engraving had preserved the look of the original.

But in the printing, left and…
