MICOLL - Maps

The MICOLL-Maps are innovative digital historical tools designed to visualize the changing routes through which merchants and commercial law terms circulated across Europe between the 11th and 17th centuries.

Bridging Geography and Legal History

The map serves as a visual counterpart to the project’s “Historical Lexicon of Commercial Law” (link), focusing on the intense Trans-Alpine exchange connecting hubs like Venice and Genoa with central and northern Europe, the Mediterranean Sea with the North Sea and the Baltic Sea. It moves beyond traditional static cartography by displaying evolution over six centuries, incorporating both land and water routes.

A core innovation of the MICOLL Map is its level of transparency, being designed as a rigorous research tool where every route and waypoint is directly linked to the underlying historical evidence allowing scholars to see and cite the specific data behind each line on the map. To develop the maps, the project utilizes both primary sources (such as historical postal itineraries) and secondary sources (contemporary literature).

A Dual-Layered Experience

To serve different audiences, the project develops two distinct mapping interfaces:

MICOLL-Map (Academic): A highly technical version designed for researchers, containing detailed references to legal-historical documents and archival sources.
MM-Map (Migrating Merchants Map): A version designed for a wider audience, enriched with biographies of merchants, anecdotes and historical images of symbolic places like the Fondaco dei Tedeschi in Venice or the Loggia della Mercanzia in Genoa. This version will utilize an ancient map as its foundational base layer (e.g. the “Atlas Maior” by Joan Bleau, 1665), providing a historically authentic backdrop upon which the itineraries are traced.

The MM-Map will be directly linked to the Atlas of Places of Mercantile Justice in Europe, an initiative currently being developed under the IUSTITIAM project. Funded by the MUR (Italian Ministry of University and Research), the IUSTITIAM project is specifically reserved for ERC grant winners and is intrinsically connected to MICOLL. This synergy allows for a comprehensive mapping of both the movement of merchants and the institutional spaces where mercantile law was administered.

For both projects, we are collaborating with MOHU (Center for Advanced Studies in Mobility & the Humanities at the University of Padua). This collaboration strengthens the project’s ability to treat trade routes not just as lines on a map, but as digital spatial infrastructures that carry the history of European legal culture.

Mapping Law and Language: The Overlap

Rather than treating the “Historical Lexicon of Commercial Law” and the Maps as separate components, MICOLL’s final aim is to integrate them to provide a 21st-century update to Eberhard Freiherr von Künßberg’s 1926 concept of Rechtssprachgeographie (Legal Language Geography). By merging Künßberg’s theoretical intuition with advanced digital tools, we would like to create a dynamic ‘geography of legal language’ where technical legal definitions and historical trade routes overlap, effectively charting the transnational migration of commercial law.

By layering the technical terminology found in our archival research onto the historical trade routes, we aim to:

Visualize Semantic Migration: The overlap allows users to see how specific legal concepts – our “semantic galaxies” – traveled and evolved physically as they moved between the Mediterranean, the North Sea, and the Baltic Sea.
Empirical Evidence of the lex mercatoria: By following the tracks of medieval and early modern merchants “on the spot”, we can visually demonstrate whether these cultural brokers truly shared a common legal language across different geographical areas.

The interactive maps will also enable users to visualize pivotal historical locations that were essential both for mercantile activity and the evolution of legal thought. Specifically, the maps will identify:

Merchant Hubs: Key commercial sites such as fairs, fondaci and harbors.
Universities: Law Schools.

By mapping Law Schools alongside commercial landmarks, we aim to visualize the spatial infrastructures where legal knowledge and commercial terminology intersected and migrated along major European trade routes.

An Interdisciplinary Synthesis

This approach bridges the gap between historical linguistics, legal history, and geography, fulfilling the project’s goal of “Charting the History of Commercial Terms”.

Availability

The map application is currently under construction and is being populated with “dug up” archival materials from across Europe. Like the Historical Lexicon, the full interactive experience will be available on this site by the project’s conclusion in March 2027.
