Why do people collect? Cicero said of the Roman governor of Sicily Gaius Verres that his appetite for Greek sculpture was called a passion by himself but a mental illness by his friends. Freud attributed the collector’s mania to bad toilet training. Others claim to have proved that it is due to abnormalities in the medial prefrontal cortex. Psychologists have filled thousands of pages on the subject in peer-reviewed journals. It is safe to assume that Christopher de Hamel has not read any of them. But in this fascinating book he presents 12 case studies of men and women with just one thing in common. They were all obsessed with acquiring, selling, making or in one case forging medieval manuscripts.

This is an important and topical book. Mary Sarotte traces the difficult course of Russia’s relations with Europe and the United States during the decade which followed the fall of the Berlin wall in 1989, a period which saw Russia’s brief dalliance with democracy and Nato’s advance to the frontiers of the old Soviet Union. The story has been told before, but never so fully or so well. In a remarkable historical coup, Sarotte has persuaded the German foreign ministry to open its archives to her, and the Americans to declassify thousands of documents previously closed to researchers. When Vladimir Putin’s spokesman Dmitry Peskov was moved to denounce so much disclosure of confidential diplomatic material, it became obvious that Sarotte was on to something.

Manuscripts have something of the appeal of drawings. They bring you closer to the creative process. Even a copy adds something special to the text: an editorial twist, a decorated initial, a margin full of beasts or just a beautiful script in which every letter is fashioned by hand like no other. Manuscripts do more than convey information. Their creation calls for imagination, physical effort, a love of meaning and beauty. They are works of art in their own right. I specialise in the most unpoetic kind of manuscript: administrative records of military and political history. But even they speak to us directly.

No one can accuse Linda Colley of shying away from big subjects. This one is as big as they come — nothing less than an exploration of the origin of written constitutions. It is built around two ideas. One is that the development of national constitutions has to be studied globally, not nationally. Only then can consistent patterns emerge. The other is that there is a consistent pattern. The great generator of written constitutions, she argues, is war. The argument is that war requires an exceptionally high degree of social organisation which makes a formal constitution desirable, perhaps even necessary. The Gun, the Ship and the Pen is a remarkable feat of scholarship on an international scale. Its reach is not quite global.

Sylvie Bermann was the French ambassador in London between 2014 and 2017. Her stint here was a notable success. She is a highly intelligent, articulate woman, excellent company, an astute observer of the British scene and a notable anglophile, who generated much goodwill for herself and her country. She has taken the opportunity of her retirement from the French diplomatic service to write a highly undiplomatic account of her time in London which will lose her a fair amount of that goodwill. Goodbye Britannia is a witty, waspish and angry account of the Brexit referendum and the political crisis which followed it. It is agreeably rude about British politicians, especially the current Prime Minister, whom she describes as a lying mountebank.

The crusades are part of everyone’s mental image of the Middle Ages. They extended, in one form or another, from the 11th to the 16th century. Those which reached the Holy Land were fought by men on horseback wearing metal armour and carrying lances and swords, as in the pictures. The onset of gunpowder had not yet spoiled the fun. They were truly international, in their own way emblematic of the myth of a single Christian European polity. They embodied everything that people associate with medieval warfare: reckless courage, murder, loot, adventure and romance. Christopher Tyerman has been writing about the crusades for nearly 40 years. His work includes the only full-scale study of English crusaders and God’s War, which for my money is the best one-volume history in print.

The illustrated manuscripts of the European Middle Ages are among the most beautiful works to survive from a maligned and misrepresented age. The darkest of the Dark Ages produced the Book of Kells and the Lindisfarne Gospels. Out of the most vicious period of France’s medieval history emerged the exquisite books of hours painted by the Limbourg brothers for the repellent Duke of Berry. Yet, unlike the panel paintings, the sculpture, the buildings or the jewellery of the period, illustrated manuscripts are almost entirely inaccessible to the public. Light, oxygen and humidity, the three great enemies of pictorial artefacts, are especially unkind to manuscripts. Vellum is made of animal skin, which naturally decays. Vege-table dyes fade. Mineral pigments discolour.

Richard Bourke’s Empire and Revolution: The Political Life of Edmund Burke (Princeton, £30.95) is a monument of exact scholarship and careful reflection, by a long way the best book that we have on this profound and much misunderstood politician and philosopher. For those who want more thunder than even Burke can offer, Rory Muir’s Wellington: Waterloo and the Fortunes of Peace, 1814–1852 (Yale, £30) completes the author’s outstanding two-volume biography. Finally, Penguin Classics confirms its reputation for range and eclecticism with Magna Carta, with a superb commentary by David Carpenter (£10.

For most of history, religion and war have been the most powerful social instincts of mankind and its chief collective activities. In the crusades, they combined to create a movement of great emotional power, which convulsed Europe in the 12th century and retained its appeal to the military classes until the end of the Middle Ages. One might expect people who embarked on a great war with such intense spiritual exultation to be unconcerned with practical planning. And there were some who believed that these mundane matters should be left to the Holy Spirit to sort out. But they tended to come to a sticky end. For most crusaders, holy war was a serious business, calling for professional organisation, ample finance and meticulous logistical preparation.
