Dates of conference: December 3–5, 2025  |  Location: Louvain-la-Neuve

The subject of the Blood of Christ has fueled Christian devotional culture in Europe since the mid-Middle Ages. Rooted in the veneration of relics, it quickly became central with the progressive establishment of the dogma of transubstantiation, particularly at the Fourth Lateran Council (1215), and the development of a liturgy specifically celebrating the Corpus Christi: the Feast of Corpus Christi, universally promoted within Christendom by the papal bull Transiturus (1264).

This interdisciplinary conference aims to explore how devotion to the Holy Blood, in its various forms and manifestations (relics, sacraments, miracles), shaped and nourished the emergence of a visual culture in Europe from the Middle Ages to the 18th century.

Through the lens of visuality—whether visible and/or visionary—this colloquium will examine the theological debates, the development and evolution of a devotional culture, including its social and political dimensions, and their impact on modes of representation in iconography. By visual/visionary culture, we aim to investigate what is rendered visible of the Blood of Christ and to explore the tension between what miracles make perceptible to the senses and what remains beyond perception, opening the faithful to a spiritual and sacred dimension and inspiring new modes of rendering the divine visible.

Proposals for contributions may align with one of the following three thematic axes:

1) Doctrinal Foundations and Eucharistic Liturgies

This axis will address the doctrinal points leading to or following the establishment of the dogma of transubstantiation and the institution of the Eucharistic liturgy. The question of the visible/visionary, which arises with the affirmation of Christ’s full and real presence in each species, created profound theological challenges concerning the status of miracles that made Christ’s Blood visible (mirari). Proposals may focus on theological debates or disputes surrounding this dogma and liturgy, examining key milestones such as the Fourth Lateran Council (1215), the Council of Constance (1418), or the Council of Trent (1545). Special attention could be given to the Feast of Corpus Christi, the cult of the Holy Blood, or specific Eucharistic miracles, such as those of Bolsena (1263), Florence (1230), Fécamp (11th century), Louvain (1347), Bruges (1146), Brussels (1370), Paris (1290), Passau (1477), or Deggendorf (1337). Contributions might also consider theological writings that sought to define or interrogate the status of these miracles and their narratives.

2) Visual/Visionary Culture in Social and Cultural History

This axis will explore the role of visual/visionary elements in cultural and social history related to the devotional culture surrounding the Holy Blood and transubstantiation. Proposals might examine dynamics contributing to a new visual culture, particularly in lay contexts and observance practices. Submissions could also address the materiality-centered liturgies, sensory-focused preaching styles blending sensory, mental, and spiritual images, or the construction of miracle narratives at the intersection of the visible and the visionary. Social and political dimensions may also be considered, analyzing how accounts of Eucharistic miracles and manifestations of the Holy Blood (pilgrimages, rituals, theatrical performances, processions) were used by clerical and secular authorities to foster community unity or as instruments of division and controversy.

3) Visualizing the Holy Blood: Object-Image Culture

This axis focuses on the visual and visionary devices that rendered the Holy Blood visible through a culture of object-images, which diversified and expanded over the centuries with the development of new media. Contributions could explore visual/visionary strategies in liturgical and para-liturgical ceremonies, increasing attention to images and their staging, the use of mobile images, the interplay of veiling and unveiling, the theatricality of certain representations, or the dialogue between illustrated manuscripts and image walls. Proposals might also consider the proliferation of small-format prints. These facets of the Holy Blood’s visual culture provide an opportunity to analyze how images functioned in thaumaturgic, visionary and soteriology, mediating between the visible and invisible and shaping new visual or visionary experiences for the faithful.

Submission Guidelines

The conference will take place from December 3–5, 2025, at the Université Catholique de Louvain (Louvain-la-Neuve). Proposals, in French or English, should not exceed 500 words and must include a CV. Submissions are due by April 1, 2025, and should be sent to manon.chaidron@uclouvain.be and mathilde.mares@gmail.com.

Selected contributions will be published in a collective volume. Proposals should emphasize themes related to visibility/invisibility and visual/visionary dynamics.
Where possible, accommodation and travel expenses will be covered.

We encourage participation from researchers across disciplines to enrich the analysis of visual culture mechanisms and foster a collective reflection on their modes of apprehension. This interdisciplinary approach offers an opportunity to situate these dynamics within a broader mental and social history of devotional movements.
