This study seeks to describe the public communication practices of the authorities in the Dutch Golden Age. It is a study of 'state communication': the manner in which the authorities sought to inform their citizens, publicise their laws, and engage publicly in quarrels with their political opponents. These communication strategies underpinned the political stability of the seventeenth-century Dutch Republic. Concerned about their decorous appearance, the regents who ruled the country always understated the extent to which they relied on the consent of their citizens. The regents shared a republican ideal which dismissed the agency of popular consent; but this was an ideal, like so many ideals in the Dutch Republic, which existed in art and literature, but was not practised in daily life. The practicalities of governance demanded that the regents of the Dutch Republic adopt a sophisticated system of communication. The authorities employed town criers and bailiffs to speed through town and country to repeat proclamations; they instructed ministers to proclaim official prayer days at church; and they ensured that everywhere, on walls, doors, pillars and public boards, one could find the texts of ordinances, notices and announcements issued by the authorities. In the seventeenth-century Dutch Republic, politics was not the prerogative of the few. That this was due to the determined efforts of the authorities has never been appreciated. Far from withholding political information, the regents were finely attuned to the benefit of involving their citizens in the affairs of state. The Dutch public was exposed to a wealth of political literature, much of it published by the state. The widespread availability of government publications also exposed the law to prying, critical eyes; and it paved the way to make the state, and the bewildering wealth of legislation it communicated, more accountable.

Société ”iconique” par excellence, les Provinces-Unies au XVIIe siècle sont un espace où la représentation graphique envahit le quotidien. Parallèlement, le mariage est une institution au cœur d’un processus de réhabilitation et de cristallisation confessionnelle de dispositions dogmatiques et disciplinaires. Il constitue en outre une expérience anthropologique fondamentale, dont chacun fait l’expérience, comme acteur ou spectateur. Dans cette perspective, les images du mariage innervent toute la culture visuelle de la société néerlandaise et sont au croisement d’enjeux sociaux, religieux et politiques, perceptibles à différentes échelles, par la symbolique qu’elles mettent en jeu et les usages sociaux qui en sont faits. Comment les différences confessionnelles s’y articulent-elles ? Comment les distinctions sociales s’y manifestent-elles ? Quels bénéfices symboliques les usages métaphoriques visuels du mariage permettent-ils d’obtenir pour les acteurs sociaux ? Enfin comment ces images fonctionnent-elles vis-à-vis du lecteur-spectateur ? A travers un corpus de sources très divers (livres ou brochures illustrés, feuilles volantes, mais aussi peintures ou médailles), la thèse répond à ces questions en examinant successivement comment les images accompagnent les discours prescriptifs sur le mariage, la façon dont elles sont mobilisées lors des noces des élites urbaines et lors de la célébration des noces princières, mais aussi comment elles permettent de donner métaphoriquement corps au lien entre le croyant et Dieu ou, paradoxalement, à celui entre le Prince d’Orange et la Patrie, dans un système politique revendiqué comme une République. / "Iconic" society par excellence, the United Provinces in the seventeenth century is a place where images play a tremendous role in daily life. Meanwhile, marriage is an institution at the heart of a rehabilitation process and of a differentiation process of confessional identities involving dogmatic and disciplinary provisions. It is also a fundamental anthropological experience, experienced by everybody in the society, be it as actor or spectator. In this perspective, the matrimonial images pervade the whole visual culture of Dutch society and are at the crossroads of social, religious and political issues, at different scales, through the symbolics they involve and the social uses they are submitted to. How are confessional differences articulated to them? How are social distinctions manifested? What symbolic benefits do social actors get out of visual metaphors of marriage? Finally, how do these images interact with the reader-viewer? Through a diverse corpus of sources (illustrated books or pamphlets, single-leaf engravings, but also paintings and medals), the thesis addresses these questions by examining successively how images accompany prescriptive discourses on marriage, how they are involved in the urban elites weddings and during wedding festivities for princes, but also how they can metaphorically embody the link between the believer and God, or, paradoxically, that between the Prince of Orange and the Fatherland, in a political system claimed to be a Republic.

Rembrandt's use of light in his self-portraits has received an abundance of scholarly attention throughout the centuries--and for good reason. His light delights the eye and captivates the mind with its textural quality and dramatic presence. At a time of scientific inquiry and religious reformation that was reshaping the way individuals understood themselves and their relationship to God, Rembrandt's light may carry more intellectual significance than has previously been thought. Looking at Rembrandt's oeuvre of self-portraits chronologically, it is apparent that something happened in his life or in his understanding that caused him to change how he used light. A distinct and consistent shift can be observed in the location and intensity of light to the crown of the forehead. This change indicates that light held particular significance for Rembrandt and that its connection to the head was a signifier with intentional meaning. This meaning could have developed as a result of Rembrandt's exposure to and interest in the contemporary theological and philosophical debates of the seventeenth-century Netherlands, particularly those relating to the physical and eternal nature of the soul stemming from the writings of René Descartes. The relative religious and intellectual freedom of the Dutch Republic provided a safe place for Descartes to publish and defend his metaphysical ideas relating to the nature of the soul and know-ability of God through personal intellectual inquiry. The widespread disturbance to established thought caused by his ideas and methods sped their dissemination into the early seventeenth-century discourse. Rembrandt's associations with the educated elite, particularly Constantijn Huygens and Jan Six, increases the probability that he knew of this new philosophy and had the opportunity to consider its relevance to his own quest for self-knowledge. With his particular emphasis on self-exploration and expression, demonstrated through his prolific oeuvre of self-portraits, and his inclination toward emotive, complex, and interdenominational religious works, it follows that Rembrandt would be eager to embrace Descartes' metaphysics and demonstrate his awareness through his self-portraits. Light on the forehead becomes a metaphor for enlightenment and is the key to reading Rembrandt's late self-portraits through the lens of Cartesian influence.
