Egypt

The Fifth Crusade, which was fought between 1217 and 1221, marked a new direction for the crusading movement of the Middle Ages. Instead of invading Palestine, as the first three crusades had done, and the Fourth Crusade might have done, the crusaders decided to attack Egypt. That was not the original idea. The formidable Pope Innocent III, who launched the Fifth Crusade, had envisaged a repeat of the old strategy of marching on Jerusalem from the sea. The invasion of Egypt was decided by the initial wave of forces after they had reached the Levant. There was a sort of logic behind the decision. The crusading kingdom of Jerusalem had been destroyed in 1187, when its army had suffered a crushing defeat at the hands of Saladin at the Horns of Hattin above the Sea of Galilee.

These legendary lives need the clutter cleared away from them occasionally. Lawrence Durrell and his brother Gerald turned their family’s prewar escape to an untouched Corfu into a myth that supplied millions of fantasies. It still bore retelling and extravagant expansion recently, if the success of ITV’s series The Durrells is any sign. (One indication of that pleasant teatime diversion’s accuracy: the actor playing Larry, Josh O’Connor, is 6ft 2in. Larry himself was a whole foot shorter.) How Louisa Durrell, struggling with life in Britain after returning from India, went in a bundle with her children to a Greek island of cheap Venetian mansions, heat and innocent adventure is always going to have its appeal.

George Orwell has a story that when Sir Walter Raleigh published the first volume of his projected history of the world while in prison, he witnessed a brawl outside his rooms in the Bloody Tower which resulted in the death of a workman. Despite diligent enquiries, Raleigh was unable to discover the cause of the quarrel. Reasoning that if he could not even ascertain the facts behind what he had observed he could hardly accurately report what had happened in distant lands centuries earlier, he burned his notes for the second volume and abandoned the entire project. No such doubts assail the 79-year-old Conrad Black, sometime proprietor of The Spectator, who, like Raleigh, has written the first of a projected three-volume global history.

Anthony Sattin begins with a quotation from Bruce Chatwin, who famously tried all his life to produce a book about nomads but never quite succeeded (the nearest he got was Songlines). Hoping to persuade Tom Maschler at Cape of the virtues of the project, Chatwin described nomads as ‘a subject that appeals to irrational instincts’ – perhaps not the best way to sell something to publishers, who tend to pride themselves on their rational ones. But Chatwin’s thesis – that we were all originally nomads and need to recover some of that instinct – is now triumphantly brought to its conclusion in Sattin’s fascinating journey through 12,000 years, from the nomadic ways of prehistoric man to the Bedouin and Maasai of today.

What particularly excites Silvia Ferrara, the author of The Greatest Invention, is not language per se but writing – that is, the specific tool created for recording and conveying language visually. Sound made visible, tangible. The impulse to communicate might be innate, but writing is cultural, and in no way inevitable. It’s a bit of tech, which needed to be developed, and which needs to be learned. Writing has many obvious benefits – allowing communication to survive across time, thus enabling cultural traditions and posterity – unlike purely synchronous conversation, face-to-face, stuck in the present. Yet as a species (and a species with memory, specifically) we could live perfectly well without it, as indeed we did.
