Prophecies and (Hi)Stories: Telling the Conquest of Constantinople in 1453

From a Euro-Mediterranean perspective, the conquest of Constantinople led by the Ottoman Sultan Mehmed II in 1453 not only marked the end of the Byzantine empire that had lasted more than a millennium, but also the end of the European Middle Ages. Rightly considered a ‘moment of great historical significance’1 by both contemporaries and modern researchers, the conquest of Constantinople ‘had repercussions that went far beyond its walls’2 not only politically and economically, but also culturally and socially.

Moreover, through surviving witnesses, word of the city’s fall spread like wildfire through the Euro-Mediterranean world. A passage from a letter written by Enea Silvio Piccolomini speaks volumes:

My hand trembles as I write this, my mind shudders and neither indignation lets me write nor does pain allow me to speak. O wretched Christendom! . . . If only I were gifted enough to lament this catastrophe with dignified words!3

Though he claims to be unable to speak properly about the recent events, Piccolomini nonetheless goes on to give vent to his thoughts. Yet this is more than a mere rhetorical flourish to display the author’s skill. In talking about despair, utter confusion, and both bodily and mental pain, Piccolomini describes more broadly the pain of loss and claims to be unable to speak, or at least uncertain about doing so. His descriptions thus render complex matters in terms of emotions, pain, abilities, temporalities, and trauma in premodern times.

Examining an event which was already considered momentous in contemporary discourse is an intricate undertaking. Even at the time, presenting recent (hi)stories to a broader audience and, therefore, producing memory in spite of its emotive content proved problematic—especially for the Byzantines. Their confrontations with extreme forms of violence made it particularly difficult for them to comprehend and reproduce what had actually happened:

What shall I say and how shall I say it? My tongue is stuck fast in my larynx. I am unable to draw breath for my mouth is sealed.4

But how can people talk about recent developments that can indeed be considered thoroughly traumatic? How did Byzantine historiographers deal with forgetting and suppressing, remembering and processing, with regard to the process of writing history?

In order to contribute to further research on the history of emotions, trauma, and pain in premodern societies, my Ph.D. project examines the narrative processing, interpretation, and attribution of meaning to the Ottoman conquest of Constantinople, looking primarily at late Byzantine historiography. Telling the Ottoman conquest was inextricably linked to end-time scenarios that recurred in prophetic texts:5 The conquest of Constantinople was seen as indicating the inevitably approaching end of the world. Thus, it is hardly surprising that historiographical material was intertwined with prophetic texts that, in turn, demonstrably influenced political decision-making. As ‘a compilation of texts culled from various sources’,6 the Oracles of Leo the Wise7 (OL) are of particular interest to me. The OL comprise fifteen very different prophetic texts, some of which are dated to events that took place after 815, some of which are dated to around 1204, and some of which were written at entirely unknown points in time. These texts were updated after the conquest of Constantinople to centre them around the Ottoman sultans rather than the Byzantine emperors, and were widely disseminated in the Euro-Mediterranean world. This post-conquest alteration can, for instance, be observed very well in the illustrated manuscript Barocci 170 at the Bodleian Library.8

That contemporary historiographers of the conquest of Constantinople drew on prophetic texts such as the OL is, however, not as self-evident as one might think, as the dissemination and possession of these prophecies had been forbidden by law since late antiquity.9 In fact, the descriptions in Late Byzantine historiographies do not correspond literally with the OL. But they do have clear thematic parallels in that they possess strikingly similar settings and refer to various ranks of the same distorted, yet somehow still socially conceived order. Furthermore, these texts hold out the prospect of a possible turn for the better—albeit in a vague way. This fits particularly well with the overarching approach taken in contemporary historiographical sources, which refute the supposedly approaching end of the world in a pragmatic reworking of existing concepts by declaring the Ottomans to be interim rulers. Including prophetic texts thus could have offered late Byzantine historiographers a suitable means to make the content more credible to their audience.

Scholars have not yet examined more precisely what exactly was so confusing, disorienting, and incisive about the Ottoman conquest of Constantinople that made it such a profound event—one whose effect is still felt to this day. Was it a sense of personal catastrophe, or did it reflect the failure of biblical assumptions or a general experience of crisis? The importance of the conquest of Constantinople in 1453 as a ‘cataclysmic event that reverberated throughout Renaissance Europe’10 is not only shown by the abundance and variety of surviving source material; it is also evident in the wide distribution of sources such as the OL in libraries and archives throughout Europe. Thus, the prophetic and historiographical traditions of the Ottoman conquest of the city formed an important part of the generation of knowledge about the Ottoman Empire and its perception in the early modern period. Furthermore, these sources are complemented by other documents ranging from threnoi, letters, and speeches to archaeological evidence.11 The dissemination of prophetic and historiographical texts on the conquest of Constantinople in 1453 throughout Europe makes research on this topic an interesting undertaking, but also a complex and laborious one. For this reason, I am grateful that the scholarship I was granted by the German Historical Institute London not only enabled me to significantly advance my research by consulting the manuscript collections in the British Library and the Bodleian Library, but also allowed me to present my project at the GHIL’s research colloquium during my stay.
