Passionate about prints, Lee Ufan had, for many years, hoped to create an extremely long etching. He wanted to push horizontality to its limits. It was at Michael Woolworth's studio in Paris that he was able to realise this dream. Applying himself, with all his physical strength, to the hardness of the steel plates and the vastness of their length, he created two different works as two ways to explore an infinite trajectory. A hard bound leporello, augmented by a separate text in which the artist explains his unique approach, accompanies the project. Both vigorous and meditative, Lee Ufan's etchings are an invitation to let our gaze drift over the lines and become lost in the voids. Fading in front of his own work, the artist thus traces for us a path to the invisible.
