Book of Hours was designed and created by Julie Chen & Keri Miki-Lani Schroeder. This long-distance collaboration, between California and Texas, took place during the 2020-21 pandemic. The format of Book of Hours is known as a blow book, a historical structure originally designed as a magic trick which allows the presenter to show completely different visual sequences of pages within the same book. Book of Hours contains 12 distinct sequences. The first and last sequences on each side of the book were designed by the two artists collaboratively, and the other eight sequences were designed individually by each artist. These different narratives exist concurrently within the same space and time of this book but are activated sequentially by the reader. The cone motif used throughout this book was inspired by the concept of the light cone which in general and special relativity denotes a single point in space and time.
Book of Hours was printed using letterpress, digital, and Risograph printing on Mohawk Superfine and Hahnemühle Bugra paper. The binding was completed at Flying Fish Press and Coyote Bones Press. The box was designed and fabricated by Keri Miki-Lani Schroeder.
