Michael Symmons Roberts’ sixth – and most ambitious collection to date – takes its name from the ancient trade in powders, chemicals, salts and dyes, paints and cures. These poems offer a similarly potent and sensory multiplicity, unified through the formal constraint of 150 poems of 15 lines.

Like the medieval psalters echoed in its title, this collection contains both the sacred and profane. Here are hymns of praise and lamentation, songs of wonder and despair, journeying effortlessly through physical and metaphysical landscapes, from financial markets and urban sprawl to deserts and dark nights of the soul.

From an encomium to a karaoke booth to a conjuration of an inverse Antarctica, this collection is a compelling, powerful search for meaning, truth and falsehood. But, as ever in Roberts’ work – notably the Whitbread Award-winning Corpus – this search is rooted in the tangible world, leavened by wit, contradiction, tenderness and sensuality.

This is Roberts’ most expansive writing yet: mystical, philosophical, earthy and elegiac. Drysaltersings of the world’s unceasing ability to surprise, and the shock and dislocation of catching your own life unawares.

This selection of the best poems from six remarkable collections reveals that all the strength and sensuality and strangeness is in there from the start. This is a metaphysical poetry for our age: rooted, steeped in the physical, but stretching for lyric completion, philosophical clarity, emotional truth. These poems achieve their seriousness not through hectoring argument but through their lightness of touch, their wit, their tenderness, their music. Roberts has always been a poet who, in the words of Lavinia Greenlaw, ‘inspires profound meditation on the nature of the soul, the body, the stars and the heart, and sparks revelation’. He is also formally and thematically diverse, restlessly exploring a wide range of subjects from Cold-War fear to love lyrics, genetics to elegies, always returning to the crucial, elemental themes – the mapping of experience and the search for meaning.

After Drysalter, his double-prize-winning tour de force, we now have this opportunity to observe the whole arc to date: the consistency of grace and power, curiosity and risk, passion and intelligence that – together – make Michael Symmons Roberts such a thrilling and essential poet.
