This is a hybrid artist’s book and drawing monograph by the Massachusetts–based painter Xylor Jane (born 1963), whose works based on or derived from numbers and other systems of order have found critical acclaim among curators and artists internationally.

Her often brightly colored, immaculately constructed and executed paintings run parallel to, and are informed by, a drawing activity that is much about notating her daily life as it is comprehending the role of numbers and their history.

This book is the first to focus on her drawings and notes, sequenced by the artist herself. This sequence, which includes work from the mid-2000s to the present, is accompanied by essays on her drawings by John Yau and Em Rooney.
