One could honour God with prayer, of course, and build cathedrals, amass treasuries, turn choirs into stained-glass jewel boxes, carve portals with saints and sinners. But for the medieval monks bent over vellum in chilly scriptoria colour, too, was devotion: offertories of lapis lazuli, azurite, cinnabar, silver and gold, gold and more gold. Silver tarnished on the page, but gold remained exquisite, inviolable, and monks and scholars found a dragonish greed for it. War, weather, revolution, Henry VIII, Oliver Cromwell, acquisitive magpies, trophy-hunters and time have stripped gold and pigment from sculptures and ivories. Frescoes have been whitewashed, mosaics scuffed, stained-glass smashed, reliquaries melted and their gems dispersed, but illuminated

Pop idol turned top boffin Brian Cox doesn’t shy away from the big issues. With programmes such as Wonders of the Solar System, Wonders of Life and Human Universe, Cox, the heir apparent to His Eminence Sir David Attenborough, has dared to dream on a cosmic scale. Are there any limits to his mighty intellect? In his latest adventure, Forces of Nature (BBC1, Monday), the ambitious prof boldly seeks to illustrate the workings of ‘the underlying laws of nature’. As wistful electronic music tinkled Eno ishly in the background, he assured us, in a metaphysical tone, that ‘the whole universe, the whole of physics, is contained in a snowflake’. Representing

William Henry Fox Talbot had many accomplishments. He was Liberal MP for Chippenham; at Cambridge he won a prize for translating a passage from Macbeth into Greek verse. Over the years he published numerous articles in scholarly journals on subjects ranging from astronomy to botany. One thing he could not do, however, was draw well — and it was this inadequacy that changed the world. While on holiday in Italy in 1832, he became so frustrated by his failure to draw Lake Como satisfactorily using a pencil and a drawing aid known as the camera lucida — his efforts were well below GCSE art standard — that he resolved to

I remember the shock, like a jolt of static electricity. One day, between taking my degree and beginning my first job, while looking through a 16th-century book about numerology that had once belonged to John Dee in the British Library, I came upon an annotation in his own neat italic hand casting up the numerical values of the letters of his name. The total he wrote down came to 666. John Dee (1527–1609) was a magus, but we must not think that this made him a loony witch. An early Fellow of Trinity College, Cambridge, teaching Greek, he acquired a reputation for learning in mathematics, navigation and astronomy. But his

They’ve already found a cure for the common cold. It’s called Technicolor. My first dose of it came during the Christmas holidays when I was about 12. There I was, ailing and miserable, when The Adventures of Robin Hood (1938) came on the television at the end of my bed. Nothing had prepared me for this. A Sherwood Forest that was aflame with green. Clothes that shimmered purple and blue. Olivia de Havilland’s oh-so-cherry lips. Under two hours later I cast off the duvet and leapt from the fug. The sickness had gone. I now know that this medicine, Three-strip Technicolor, was a revolutionary process, the first to properly mix
