This exhibition, 40 years after the death of this remarkable artist, focuses on his later work of lithographs and colour prints. It provides a wonderful introduction to, or re-acquaintance with, Richards’s work and a spur to seek out more of it, including the substantial collection at The Tate and The Glynn Vivian Art Gallery, Swansea where Richards held his first show in 1930.

Richards was born in 1903 into a Welsh working-class family. He developed an early love of music and poetry as well of fine art. These became major influences on his work.

He would return to a theme, working and reworking it to capture extreme detail, flights of fancy and the many faceted nature of his subject matter.

The Arts Council commissioned him to celebrate the Festival of Britain, which he did with his Trafalgar Square sequence. He returned to the theme in 1962 with a number of lithographs, one of which is in this show.

In the 1940s, he was influenced by Dylan Thomas’s poetry. The colour lithograph The Author’s Prologue (A Fragment) 1965 is based on a poem celebrating a heron’s successful catch in fish-rich waters.

Music and composers also inspired Richards. This was Debussy, in the case of The Origins of A Rose, 1967, (pictured above) where he creates a rhythmical piece with a skeletal central leaf, its image highlighted by a commanding red surround over-printed in muted blacks and turquoise.

The three prints, on show, from his series Beethoven Suite with Variations are a delight. Missa Solemnis, 1970, includes a reproduction of a sketch of a hatted barrel-chested Beethoven, set against a vivid, expansive, surrealist background.

The exhibition is at Art Jericho, in King Street. The show is open Tuesday to Sunday and continues until July 22.
