INSTITUTIONES PHILOSOPHICÆ

### In Regio Eporediensi Lycæo Traditæ

**Latin philosophical and scientific manuscript from the 18th century, dated 1764**

An important handwritten testimony of the philosophical and scientific culture of the eighteenth century, expression of that academic tradition in which logic, metaphysics, geometry, and the study of nature formed the indispensable foundations of intellectual formation.

The work, titled *Institutiones Philosophicæ in Regio Eporediensi Lycæo Traditæ*, presents itself as an articulated compendium of philosophical teachings imparted at the Regio Liceo of Ivrea, the ancient Roman Eporedia, cultural and administrative center of the Sabaudian territories.

The date MDCCLXIV, corresponding to 1764, readable at the bottom part of the frontispiece, places the manuscript in a particularly significant moment in European history: the full century of the Enlightenment, when the advances of the scientific revolution and the new currents of rationalist thought were progressively transforming the teaching of philosophy, without erasing the influence of the great Aristotelian and scholastic tradition.

The manuscript thus constitutes a precious testimony of the eighteenth-century intellectual world, in which knowledge was still conceived as a unified system, capable of encompassing both the abstract principles of being and the mathematical laws governing the universe.

## The historical context: Piedmont under the Enlightenment

The composition of the manuscript fits within the cultural life of the Kingdom of Sardinia during the reign of Charles Emmanuel III of Savoy, sovereign from 1730 to 1773.

18th-century Piedmont was then undergoing a period of institutional, administrative, and cultural consolidation, continuing the state reorganization process begun by Vittorio Amedeo II.

Particular importance was given to education, considered a fundamental tool for the formation of the clergy, public officials, and the ruling classes. Philosophy occupied a central position in higher education and constituted the necessary foundation for the deeper study of theology, jurisprudence, medicine, and mathematical sciences.

It is in this environment that the *Institutiones Philosophicæ* are placed, whose title explicitly recalls the educational activity of the Regio Liceo of Ivrea.

The Latin expression *in Regio Eporediensi Lycæo Traditæ*, translatable as “taught at the Regio Liceo of Ivrea,” gives the manuscript an institutional identity of particular interest: not a mere private collection of philosophical reflections, but a text directly linked to the transmission of knowledge within a recognized school environment.

The presence of an orderly expository structure, with propositions, demonstrations, and geometric figures, suggests a didactic destination, plausibly a collection of lectures, transcription of a course, or a compendium for study.

The identity of the teacher and that of any scribe are not ascertainable from the pages examined.

## The structure of the work: from geometry to metaphysics

One of the most significant aspects of the manuscript lies in the breadth of disciplines addressed.

The photographs show a sequence of pages devoted to Euclidean geometry, with numerous graphical constructions, followed by the conclusion of a metaphysical section.

This coexistence testifies to a cognitive approach deeply rooted in the European philosophical tradition, where mathematics was not an isolated discipline but an essential tool to train the mind for rigorous reasoning.

The geometric pages present problems related to the construction of triangles, the intersection of circles, the properties of angles, lines, and parallelograms.

The exposition appears organized according to the classical model of demonstrative geometry: statement of the problem, construction of the figure, solution and demonstration.

Terms such as *Propositio*, *Problema*, *Resolutio*, and *Demonstratio* appear, directly recalling the methodological language of the Euclidean tradition.

Particularly revealing are constructions with two intersecting circles used to solve fundamental geometric problems, including the construction of an equilateral triangle.

This is a procedure traceable to the first proposition of the first book of Euclid’s *Elements*, one of the most influential works in the entire history of mathematics.

For more than two thousand years, the *Elements* represented the paradigm of deductive reasoning: a system in which every conclusion had to descend logically from definitions, postulates, and previously demonstrated propositions.

The manuscript thus testifies to the extraordinary continuity of a scientific tradition born in ancient Greek civilization and still fully operative in educational institutions of the XVIII century.

## The iconographic apparatus: the handwritten geometric figures

Of particular interest is the graphic apparatus that accompanies the text.

The pages preserve numerous hand-drawn geometric figures, consisting of circles, triangles, segments, lines, and parallelograms, supplemented by alphabetic letters intended to identify the different points of the constructions.

These illustrations do not perform an ornamental function, but represent an essential component of the scientific exposition.

Each figure is indeed the visual translation of a mathematical argument, allowing the reader to follow the sequence of operations and verify the validity of the demonstrations.

The handwritten execution gives these diagrams a particular charm. The lines, sometimes light and barely perceptible, retain the irregularities typical of manual drawing, while the reference letters are integrated directly into the constructions.

They are not copperplate or woodcut plates produced by a printer, but drawings made within the compilation of the manuscript.

It is not possible to determine with certainty whether they are the work of the same copyist responsible for the text or of another hand.

Their presence, however, greatly enhances the historical and documentary interest of the volume, making it concrete testimony of mathematical teaching and learning practices in the eighteenth century.

## Metaphysics and the European philosophical tradition

Another notable element emerges from page 393, where, in a central position, appears the concluding formula:

**«Finis Metaphysicæ»**

These words, i.e., “End of Metaphysics,” attest to the conclusion of a section devoted to one of the fundamental disciplines of traditional philosophy.

Metaphysics, in its classic sense, investigates the first principles of reality, the nature of being, the fundamental causes of things, and the conditions of knowledge.

Its teaching in the eighteenth century placed it within a long tradition that, starting from Aristotle, had traversed medieval philosophy, scholasticism, and modern rationalism.

The reflections of Thomas Aquinas, Francisco Suárez, René Descartes, Gottfried Wilhelm Leibniz, and Christian Wolff had contributed, in different times and perspectives, to defining the language and fundamental problems of the discipline.

Particularly important, to understand the cultural context of the manuscript, is the figure of Christian Wolff, a German philosopher who in the first half of the eighteenth century proposed a rational and rigorous organization of the entire philosophical knowledge.

His method, based on definitions, propositions, and demonstrations, exerted wide influence on European academic culture.

However, it would be improper to attribute directly the contents of the manuscript to the Wolffian school without thorough textual comparison.

More prudently, one can observe how the work belongs to an intellectual environment where systematic order and rational demonstration were of fundamental importance.

The presence of the metaphysical section, alongside geometric treatises, thus returns the image of a knowledge still deeply unified, where understanding of natural reality and that of philosophical principles were considered complementary parts of the same formation.

## A manuscript in Voltaire, Rousseau, and the Encyclopædia era

The date of 1764 gives the work a particularly evocative historical interest.

In the same year, Voltaire published the famous *Dictionnaire philosophique portatif*, destined to become one of the emblematic texts of the Enlightenment critique of traditional intellectual and religious authorities.

It had only been two years since the publication of Jean-Jacques Rousseau’s *Social Contract* and *Émile*, two works that had deeply unsettled European debate on society, education, and the nature of man.

Meanwhile, in Paris, the great undertaking of the *Encyclopédie* directed by Denis Diderot and Jean le Rond d’Alembert continued, a monumental editorial project aimed at collecting and systematically organizing human knowledge.

The Ivrea manuscript thus originates in a Europe shaken by profound intellectual changes.

On one side, the Enlightenment proposed new forms of critical inquiry and growing trust in reason; on the other, educational institutions continued to transmit the fundamentals of traditional philosophy and classical geometry.

These two worlds were not necessarily opposed.

eighteenth-century culture was indeed characterized by a complex intertwining of continuity and innovation, in which methods inherited from antiquity could coexist with new scientific and rationalist aspirations.

The *Institutiones Philosophicæ* constitute a meaningful testimony of this scenario: a document that allows us to observe not only the great transformations of European thought but also how knowledge was concretely transmitted in the educational institutions of a Piedmontese city.

## The material characteristics and the manuscript testimony

From a material point of view, the volume presents an ancient parchment binding, with a raised spine and a title piece bearing an abbreviated title relating to the *Institutiones Philosophicæ*.

The parchment shows a natural patina of antiquity, with chromatic variations, signs of use, and traces of the passage of time that attest to its long preservation.

The body of the manuscript consists of ivory-toned sheets, written in brown ink with a seven-teenth-century-looking Latin cursive script.

The writing appears generally orderly, yet preserving the characteristics typical of a manually compiled text, with fluctuations in the ductus, in the size of the letters, and in the distribution of spaces.

The photographs document a manuscript pagination that reaches at least page 393, a circumstance that reveals a work of considerable extent.

The frontispiece, also handwritten, presents the title in larger uppercase characters, followed by the indication of the educational institution and the dating.

The absence of a typographic indication, combined with the entirely handwritten nature of the examined pages, confirms that we are not facing a printed edition, but a document produced through manual writing.

The value of such testimony lies precisely in its material individuality.

Unlike a printed book, intended to reproduce a text in numerous copies, the manuscript preserves the particular characteristics of its own drafting: the script, the layout choices, the hand-drawn figures, and possible peculiarities introduced during transcription.

Each of these elements can contribute to the reconstruction of the history of teaching and the circulation of knowledge.

## Historical and collecting significance

The interest of the *Institutiones Philosophicæ* develops on several levels.

First of all, the work represents a testimony to the history of education in Piedmont under the Savoy monarchy, documenting a philosophical course linked to the Regio Liceo of Ivrea.

Secondly, it offers material testimony of eighteenth-century scientific culture, through the use of geometric demonstrations and a mathematical language derived from the Euclidean tradition.

Of particular importance is also the relationship between mathematical sciences and philosophical disciplines, which allows us to understand how knowledge was organized and transmitted before the definitive specialization of modern academic disciplines.

Finally, the manuscript nature of the volume gives the copy a specific interest for the history of the book, of writing, and of teaching practices.

Its importance does not necessarily depend on the presence of a famous author or a revolutionary theory, but on its ability to preserve a direct testimony of an eighteenth-century cultural and institutional environment.

In this sense, the manuscript belongs to that category of documents that allow the historian to reconstruct the daily life of knowledge: not only what great philosophers published, but what was actually taught, studied, and transcribed.

## Conclusion

The *Institutiones Philosophicæ in Regio Eporediensi Lycæo Traditæ*, dated 1764, constitute a fascinating testimony of philosophical and scientific formation in eighteenth-century Europe.

Through its handwritten pages, its geometric constructions, and its metaphysical reflections, the work reveals the character of an era in which knowledge was still conceived as a grand intellectual architecture, founded on reason, demonstration, and the pursuit of universal principles.

Its link with the Regio Liceo of Ivrea enhances its documentary value, placing it within a precise institutional reality of Piedmontese Savoy, while the dating to 1764 places it at the heart of one of the most fertile and complex periods of the history of Western thought.

Preserved in its manuscript guise and in its ancient parchment binding, the volume represents not only a scholarly document but a tangible testimony of the transmission of knowledge through the centuries.

**A work that, in the quiet succession of its pages, guards the memory of a seventeenth-century philosophical teaching and of that inexhaustible human aspiration to understand, order, and explain the world through reason.**
