This book enlarges the traditional catalog of labyrinths so much and so well, being itself labyrinthine,” remarked French deconstructionist philosopher Jean-Luc Nancy on the first edition of the text. The starting point for this transcript of four lectures is a public artwork that Olaf Nicolai installed in Paris in 1998. Nicolai, whose work has been shown at Documenta X and the 49th and 50th Venice Biennales, uses diverse media to question the ways in which we use our physical bodies to encounter the everyday environment. By exploring and combining a broad spectrum of topics related to the labyrinth theme, the book serves as both a reference system to Nicolai’s work and an independent source book dealing with labyrinthian matter, from the fable of the minotaur to the floor plan of IKEA.
