From saints and relics to #MeToo, this fascinating history traces the surprising cultural power of the humble snog. - Clement Knox, Daily TelegraphFrom foot-kissing knights to baby-kissing politicians, to the “shut-up kiss” of Hollywood romcoms, this rich and fascinating history reminds us that kissing is, and always has been, a contested public gesture as well as a private pleasure . . . Even the most apparently spontaneous of kisses can be shot through with power and politics. As Barclay’s timely book reminds us, it was ever thus. - Tiffany Watt Smith, The GuardianThe romantic kiss has a surprisingly radical past – from binding peace treaties to demonstrating fealty . . . [A] fascinating new book. - Ross Bilton, The AustralianAcross a thousand years of European history, [Barclay] shows us, kisses have sealed contracts, established political loyalties, humiliated enemies , sanctified believers, bound together revolutionaries and, only relatively recently, become primarily associated with swooning romance. If that sounds like rather a lot to ask of a pair of lips, Barclay's impressive command of some truly beautiful evidence goes a long way towards making such an ambitious case . . . Barclay draws variously on art, literature, theology, legal records and popular culture with impressive ease. It goes without saying that no reader will finish this book without learning a remarkable amount about kissing . . . The Kiss is a rich and often surprising book. Barclay has an enviable talent for uncovering forgotten meaning in the most ordinary practices, and she does an excellent job of showing that the history of kissing is about much, much more than romance. - Sarah Jones, HistoryExtraPucker up, because kisses are important.

Hers is a history of the changing meanings of a symbol over centuries, of social practices and of representation . . . Today, the practice of kissing is, Barclay reminds us, imbued with historic and cultural meanings which inform new representations and feelings. - Dr. Charlie Lynch, The NationalWe know that the kiss is not universal, that it has acquired and lost different functions over time, but Katie Barclay has gone deep to produce a thrilling cultural archaeology of this most intimate human act. A wonderful book. Mwah! Mwah! - Matthew Sweet, broadcaster and authorWhether passionate, dutiful, spiritual or political, kissing has long been part of the human experience. In The Kiss, Katie Barclay illuminates the rich history and changing meanings of kissing over the past thousand years. This is a curious and endlessly surprising cultural history. - Michelle Arrow, former President of the Australian Historical AssociationThis is an impressive piece of work as well as an enjoyable read. In tracing a major form of human expression from the Middle Ages to the later 20th century, Katie Barclay combines this ambitious range with persuasive analysis. - Peter N. Stearns, author of Shame: A Brief HistoryFrom the medieval Annunciation to the #metoo movement, this insightful account tracks the history of the kiss as sacred and sensual, romantic and political, intimate gesture and public spectacle. Marshalling a huge range of material, including literature, art, letters, film and science, Barclay presents a compelling history of how the dynamics and transformative power of the kiss have changed. This lucid book exposes the deep roots of how we understand and experience the kiss today. - Karen Harvey, author of The Imposteress Rabbit Breeder: Mary Toft and Eighteenth-Century England
