For over 20 years, Sarah Sze (born 1969) has produced celebrated works of art, synthesizing a near boundless range of everyday materials into intricate constructions that are both delicate and overwhelming. Sze’s monumental site-specific installation Timekeeper, originally presented at the Rose Art Museum and now in the collection of the Guggenheim Museum, combines sculpture, video and installation into a sprawling experiential work that approaches some of the most complex themes of her career: time’s passage and its marking in mechanical and biological forms.

The Timekeeper installation was a catalyst for a book which explores major new ideas in Sze’s work and practice. This ambitious work is extensively documented here alongside significant new texts by noted scholars on Sze and the themes that inform—and are informed by—her art, including the experience of time. In addition to the scholarly texts and abundant photographs of the work, the Timekeeper catalogue includes a section designed by Sze that function as a flip book to demonstrate the movement of time.
