Introduction
The law of Ancient Rome, particularly as codified in the sixth-century Corpus Juris Civilis (CJC) by the Emperor Justinian, represents one of the most significant legacies of the classical world. However, the survival of this complex legal system and its transformation into a foundational element of modern European legal traditions, including Roman-Dutch law, was not a simple process. It depended on the intellectual labour of successive generations of jurists. The question of what role, if any, was played by groups such as the glossators, post-glossators, Hugo Grotius, and other Dutch scholars is central to understanding this history. This essay will critically examine the contribution of these groups, arguing that they were not merely passive preservers of an ancient text, but active agents in a continuous process of interpretation, adaptation, and systematisation. It will be argued that each group played a distinct and essential role, with the glossators rescuing the text, the post-glossators making it practical, and the Dutch jurists, including Grotius, refining it into a rational and modern legal science that extended far beyond the borders of Europe.
The Glossators: The Rediscovery and Preservation of Roman Law
The story of Roman law's revival begins in the late eleventh century with its rediscovery in Italian libraries. The school of jurists that emerged, primarily at the University of Bologna, became known as the glossators. Their primary task was to understand the CJC, a vast and difficult collection of texts that had been largely forgotten in Western Europe for centuries. Their method, from which they derive their name, was the glossa, or gloss (Berman, 1983). These were annotations written between the lines (glossa interlinearis) and in the margins (glossa marginalis) of the manuscript.
The role of the glossators, exemplified by figures like Irnerius and Accursius, was fundamentally one of exegesis and reconstruction. They sought to explain difficult terminology, clarify obscure passages, and resolve apparent contradictions within the CJC. Accursius's Glossa Ordinaria (c. 1240) became the definitive compilation of these efforts, a comprehensive commentary that was so highly regarded it was said that 'what the gloss does not acknowledge, the court does not acknowledge' (what the gloss does not recognise, the court does not recognise). Their fundamental achievement was to rescue the CJC from obscurity and render it intelligible to medieval minds (Stein, 1999).
However, their contribution must be viewed critically. The glossators' approach was profoundly ahistorical. They treated the CJC as a single, divinely inspired text that was internally consistent and universally applicable, much like the Bible (Van Caenegem, 1992). They had little sense of the centuries of legal development that the CJC encompassed, from the early Republic to the late Empire. This led them to interpretations that were textually ingenious but often divorced from the original social and historical context of the laws they were studying. Their role was therefore essential but limited: they were brilliant textual scholars and preservers, but not yet creators of a practical, living law for their own time.
The Post-Glossators: Adapting Roman Law for a New Age
By the late thirteenth and fourteenth centuries, the focus of legal scholarship shifted from pure textual explanation to practical application. This new approach was pioneered by the Ultramontani (jurists 'from beyond the mountains' in France, such as Jacques de Révigny) but perfected in Italy by the post-glossators, also known as the Commentators. The most famous of these were Bartolus of Sassoferrato and his student Baldus de Ubaldis.
The Commentators moved beyond the gloss to write extensive commentaries (commentaria) and legal opinions (consilia) that aimed to adapt Roman principles to the contemporary needs of the bustling commercial city-states of medieval Italy. Their method, the mos italicus, was pragmatic and creative. They used scholastic logic to extract general principles (ratio legis) from specific Roman texts and then applied these principles to new problems for which the CJC offered no direct answer (Cairns and du Plessis, 2010). They synthesised Roman law with local statutes, feudal law, and canon law, effectively creating a new common law for Europe, the ius commune. Bartolus’s work on the conflict of laws, for example, developed principles to determine which city’s statutes should apply in a dispute involving citizens from different territories, a problem unknown to the unified Roman Empire but vital to medieval Italy.
Critically, while the Commentators created a highly successful and usable body of law, they were later accused by Renaissance humanists of being unscholarly. Their Latin was considered barbaric, and their focus on practical application often led them to twist the meaning of Roman texts to fit their desired conclusions. As Peter Stein (1999, p. 55) notes, their aim was not historical truth but practical utility. Their role was therefore that of creative adaptation. They transformed Roman law from an object of academic study into the mainspring of legal practice across much of Europe, even if this meant sacrificing historical purity.
Hugo Grotius and the Dutch Scholars: Systematisation and the Birth of Roman-Dutch Law
The next major development came with the rise of legal humanism in the sixteenth century, which advocated a return to the original classical sources (ad fontes). This mos gallicus (French style) criticised the Bartolists for their poor Latin and unhistorical approach. This intellectual current deeply influenced the jurists of the newly independent Dutch Republic in the seventeenth century, a period often called the Dutch Golden Age. These scholars, known as the Dutch ‘Elegant School’, sought to combine the humanists’ historical rigour with the commentators’ practical focus.
Hugo Grotius stands as a towering figure in this tradition. In his seminal work, Inleidinge tot de Hollandsche Rechtsgeleerdheid (Introduction to the Jurisprudence of Holland, 1631), Grotius did something new. Instead of writing another commentary on the CJC, he produced the first systematic treatise on the law of a particular Dutch province (Holland). He built a coherent system based on reason and natural law principles, using Roman law as a primary source but integrating it with local Dutch customs (Zimmermann and Visser, 1996). For Grotius, Roman law was not binding because it was the command of an emperor, but because its principles were aligned with reason—it was ‘written reason’. This approach elevated law from a collection of ancient texts to a rational science.
Following Grotius, other Dutch scholars such as Simon van Leeuwen, Ulrich Huber, and Johannes Voet built on this foundation. Voet’s monumental Commentarius ad Pandectas became a leading authority across Europe. These jurists completed the process of creating a distinct legal system: Roman-Dutch law. This was not pure Roman law, but a synthesis of Roman principles (as received through the work of the glossators and commentators) and Germanic customary law, all organised and systematised according to the principles of humanism and rationalism (Lee, 1953). The role of these scholars was one of synthesis and rationalisation. They took the raw materials provided by their predecessors and constructed a polished, modern legal system.
The success of their work is shown by its lasting influence. As the Dutch built a global trading empire, Roman-Dutch law was exported to their colonies. While it has since been replaced by the Napoleonic Code in the Netherlands itself, it remains a foundational part of the legal systems of South Africa, Sri Lanka, and Guyana, demonstrating its enduring utility and intellectual power.
Conclusion
In conclusion, the development of Roman law after the fall of Rome into the modern system of Roman-Dutch law was the result of a long and collaborative intellectual effort. The question's suggestion of "if, any" role can be firmly rejected. The role of these jurists was not only significant but indispensable. Each group built upon the work of the last, playing a distinct but necessary part in the process. The glossators were the diligent archivists who rescued and preserved the foundational texts. The post-glossators were the pragmatic engineers who adapted this ancient material for practical use, creating the European ius commune. Finally, Hugo Grotius and the Dutch scholars were the master architects who systematised and rationalised the law, building the elegant and enduring structure of Roman-Dutch law. This journey, from textual note to systematic treatise, demonstrates how a body of ancient law was transformed, through centuries of critical examination and creative scholarship, into a living legal tradition with a truly global reach.
