art. Several editions of A Humument have been published over the years, with more pages being revised each time. The sixth and final edition was published in 2016. 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). He was also fond of re-using images from postcards (which he avidly collected), as well as drawing stencil-style lettering, freehand. With these works, Phillips used famous pieces of literature and art in his work. The melding of visual art with textual content was a hallmark of his work. He also painted portraits (his portrait of Dame Iris Murdoch is well known) and murals, and created installation art and sculpture. His portrait of Michael Kustow won joint Hunting Art Prize in 1988. Phillips was a member of the Royal Academy (since 1989) and, in 2003 designed a Royal Mint commemorative five-pound coin for the 50th anniversary of the 1953 coronation of Queen Elizabeth II. He was an opera fan, and composed an opera, Irma, using the Humument source material for the libretto. He also wrote the libretto for Heart of Darkness, a chamber opera with music by Tarik O'Regan currently in development with American Opera Projects. Phillips engaged in other projects that challenge the viewer's perceptions of art, such as his project 20 Sites n Years, in which he photographed the same 20 spots in his studio's neighborhood, once a year. As the years go by, the viewer watches the neighbourhood gradually change. Similarly, Phillips made a series of paintings called Terminal Greys, consisting of simple cross-hatched bars of murky, grayish paint composed from the leftovers on his palette at the end of each work day. Since there are no aesthetic judgments on the artist's part in the creation of these works, they are virtually mechanical; the "art" could be said to lie in the conception of the work and not in the accidental "grey rainbow" appearance of the result. He collaborated with film director Peter Greenaway on A TV Dante, a television miniseries adaptation of the first eight cantos of the Inferno. Phillips provided cover art for music albums including Starless and Bible Black by King Crimson (1974), Another Green World by Brian Eno (1975), and one of the 16 portraits that form Peter Blake's design for Face Dances by The Who
