A Humument: A treated Victorian novel is an altered book by British artist Tom Phillips, published in its first edition in 1970 and completed in 2016.

From being created over many decades, it follows a nonlinear narrative, and in recent editions Phillips has rewritten pages to include references to modern history that in part appear to be anachronistic.

Phillips used the same technique (always with the Mallock source material) in many of his other works, including the illustration of his own translation of Dante's Inferno, (published in 1985).

For instance in the early 1970s, the Music Department at the University of York performed an opera, Irma, devised by Phillips in 1969, whose lyrics and plot were based on A Humument.

A 'final' printed edition, extensively reworked by Phillips, was published by Thames & Hudson in 2016,[1] and reviewed by Clare Pettitt in the Times Literary Supplement.
