Ball notes that purple dye made from buccinum shellfish and controlled by royal decree in Imperial Rome is

Ball notes that purple dye made from buccinum shellfish and controlled by royal decree in Imperial Rome is virtually identical to a dye from the Indigofera pea plant, native to India We know the latter better as indigo. In turn, the indigo molecule is the blue colourant in woad, used as face paint by the Celts in their battles with the Roman legions. Synthetic formulations for these purples did not appear until the 1850s, when William Perkin produced the first commercially viable aniline dyes (based on hydrocarbons) in a garden shed in east London. One bonus of this book are the fine illustrations demonstrating how artists from Raphael to Anish Kapoor have used colour. Ball ends by quietly lamenting the lack of colourists among contemporary artists, but, oddly, his book fails to mention such modern masters of colour as Howard Hodgkin and Craigie Aitchison. Gaudi, by Gijs van Hensbergen (HarperCollins, £9.99, 322pp)Antoni Gaudi is a wonderful subject for a biography, and not only for his astoundingly idiosyncratic buildings: part medieval, part daringly avant-garde. A celibate vegetarian, the architect spent his life in a whirl of passionate activity.

At 73, he was imprisoned for his part in a Catalan independence demo. At 77, while stomping his customary unswerving path to his great Barcelona church, the Sagrada Familia (started in 1889 and due to be completed in 2030), he was run over by a tram. What a pity his design for a Manhattan hotel never came to fruition.Cherry, by Sara Wheeler (Vintage, £7.99, 354pp)In this brilliant biography of the polar explorer Apsley Cherry-Garrard, Sara Wheeler successfully negotiates two problems. First, his own account of Scott’s Antarctic expedition, The Worst Journey in the World, is probably the best adventure yarn ever published.

Wheeler combines it with the reminiscences of others (Captain Oates wrote: “I dislike Scott intensely”) and also contributes historical perspective and psychological acuity. Her second problem is her subject’s uneventful life after the First World War. In fact, her sensitive investigation of Cherry-Garrard’s depression is almost as enthralling as his great adventure.Begums, Thugs and White Mughals, by Fanny Parkes, (Sickle Moon, £9.99, 362pp)As William Dalrymple notes in his introduction, these Indian journals (1822-1839) cover the “crossover chutnification” of the author, a starchy memsahib who transforms into an ardent admirer of India. She ends up playing the sitar and taking opium (“I became very happy, felt no fatigue and talked incessantly”). No matter how shocked Fanny is by what she sees – her boatmen refuse to touch a body that might still be alive; a holy man’s fingernails growing through his palm so they emerge from the back of his hand – she is never less than fascinated.John Ruskin, by Tim Hilton (Yale, £14.99, 947pp)By marrying Tim Hilton’s two already substantial volumes on the great art critic, Yale has engendered a biography that is virtually cubic. Yet this vast, detailed portrait is far from being a mausoleum.
