During the early modern period the public postal systems became central pillars of the emerging public sphere. Despite the importance of the post in the transformation of communication, commerce and culture, little has been known about the functioning of the post or how it affected the lives of its users and their societies. In Postal culture in Europe, 1500-1800, Jay Caplan provides the first historical and cultural analysis of the practical conditions of letter-exchange at the dawn of the modern age. Caplan opens his analysis by exploring the economic, political, social and existential interests that were invested in the postal service, and traces the history of the three main European postal systems of the era, the Thurn and Taxis, the French Royal Post and the British Post Office. He then explores how the post worked, from the folding and sealing of letters to their collection, sorting, and transportation. Beyond providing service to the general public, these systems also furnished early modern states with substantial revenue and effective surveillance tools in the form of the Black Cabinets or Black Chambers. Caplan explains how postal services highlighted the tension between state power and the emerging concept of the free individual, with rights to private communication outside the public sphere. Postal systems therefore affected how letter writers and readers conceived and expressed themselves as individuals, which the author demonstrates through an examination of the correspondence of Voltaire and Rousseau, not merely as texts but as communicative acts. Ultimately, Jay Caplan provides readers with both a comprehensive overview of the changes wrought by the newly-public postal system - from the sounds that one heard to the perception of time and distance - and a thought provoking account of the expectations and desires that have led to our culture of instant communication.

Long before the guillotines of the 1789 Revolution brought a grisly political end to the ancien regime, Jay Caplan argues, the culture of absolutism had already perished. "In the King's Wake" traces the emergence of a post-absolutist culture across a wide range of works and genres: Saint-Simon's memoirs of Louis XIV and the Regency; Voltaire's first tragedy, "Oedipe;" Watteau's last great painting, "L'Enseigne de Gersaint;" the plays of Marivaux; and Casanova's "History of My Life."
While absolutist culture had focused on value directly represented in people (e.g., those of noble blood) and things (e.g., coins made of precious metals), post-absolutist culture instead explored the capacity of signs to stand for something real (e.g., John Law's banknotes or Marivaux's plays in which actions rather than birth signify nobility). Between the image of the Sun King and visions of the godlike Romantic self, Caplan discovers a post-absolutist France wracked by surprisingly modern conflicts over the true sources of value and legitimacy.
