Who is Cornelius Agrippa?

Cornelius Agrippa, his full name Henri-Corneille Agrippa de Nettesheim is one of the figures who left an indelible mark on esotericism and occultism. Born in Germany in the 15th century, he spent most of his life in France where he taught his knowledge within universities and circles. Introduction.

A youth immersed in knowledge

Heinrich Cornelius Agrippa was born in 1486 in Cologne, a city that at the time was a true cultural and intellectual crossroads of the Holy Roman Empire. This Rhineland metropolis, rich in libraries and universities, provided Agrippa with fertile ground for his initial education. From a young age, he showed a keen interest in classical disciplines, immersing himself in the writings of Greece and Rome, which formed the basis of his humanist education.

At the age of fifteen, Agrippa entered the University of Cologne, an institution dominated by scholastic teachings but also influenced by the early winds of humanism beginning to blow across Europe. There, he immersed himself in the study of law, theology, and philosophy, while also taking an interest in the occult sciences that were gaining popularity. It was during these university years that he began to seriously explore Hermeticism, a current of thought seeking to reconcile mystical knowledge with Christian doctrines, drawing on figures like Hermes Trismegistus.

Agrippa was multilingual, mastering German, French, Italian, Spanish, English, Latin, Greek, and Hebrew. His skills extended to an impressive range of disciplines, including astrology, magic, classical literature, medicine, law, theology, philosophy, as well as military art and poliorcetics (the art and techniques of besieging cities). He also had expertise in explosives, Christian Kabbalah, exegesis (in-depth study of texts), diplomacy, cryptography, espionage, and pedagogy.

A distinguished career among the powerful

After completing his studies at the University of Cologne, Agrippa embarked on a military career, serving in the army of Emperor Maximilian I. This allowed him to travel across Europe, where he continued to study and gather various esoteric and philosophical knowledge. His ability to navigate between the military and academic worlds from a young age demonstrates his versatility and adaptability. He thus wrote one of his first works, On the Nobility and Preeminence of the Female Sex, which formalizes the entire divine power of sacred femininity.

Agrippa later entered the service of several European noble courts. He was notably called to Metz, where he held the position of advisor and lecturer in occult sciences and philosophy. His diplomatic skills also earned him special missions, such as the one where he was sent by Margaret of Austria, the regent of the Netherlands, to help negotiate political and intellectual matters.

Besides his military and diplomatic roles, Agrippa pursued a career as a teacher and researcher. From 1509, he held academic positions at the University of Dole in France (founded by a papal bull of Martin V, it was mainly focused on teaching law and enjoyed some renown due to the quality of its legal education). He taught theology, despite the controversies some of his ideas sparked among his peers and ecclesiastical authorities. His teachings in Dole were interrupted due to opposition from local theologians and Agrippa's teachings being labeled as controversial, which forced him to leave the city.

Indeed, his intellectual approach, which sought to reconcile various forms of esoteric knowledge with Christian teachings, including notably theoccultism, Kabbalah, magic, or astrology were often viewed with suspicion by the Catholic Church because they could be interpreted as forms of challenge to the Christian worldview.   

By the way, as an anecdote, Agrippa entered the University of Dole in June 1509 and was expelled in March 1509. This is not a typo, but that era was governed by the Easter calendar and not the Gregorian calendar as today, which means the year began at Easter.

Avant-garde and highly critical works

De Occulta Philosophia

De Occulta Philosophia Libri Tres, often abbreviated as De Occulta Philosophia, is Cornelius Agrippa's most famous work. Composed of three books, this vast encyclopedia of magic and occultism was written in the early 16th century but published in its complete form only in 1533. It is structured as follows:

• Natural Magic: this book deals with magic that interacts with the natural world, exploring the properties of plants, stones, animals, and other natural elements. Agrippa discusses how natural forces can be used to produce magical effects through symbols and correspondences.

• Celestial Magic: the second book focuses on astrology and the impact of celestial bodies on the earthly world. Agrippa examines how astrological configurations influence individuals and how these forces can be manipulated through talismanic magic.

• Ceremonial Magic: the last book addresses the highest magic, involving rituals, invocations, and the manipulation of spiritual and divine forces, notably the use of sacred names and angelic hierarchies.

The work seeks to establish a synthesis between magical practice and Christian theology, arguing that true magic, founded on wisdom and understanding of the laws of nature, is not only lawful but also a manifestation of divine piety. De Occulta Philosophia had a considerable influence on the development of Western esotericism, inspiring many occult thinkers and practitioners in the following centuries.

However, it should be known that he added a note a few years later partly questioning his own magical certainties (notably certain occult figures such as Hermes Trismegistus or demonology for example) but confirming that natural magic is indeed real.

De nobilitate et praecellentia foeminei sexus

Published in 1529, De nobilitate et praecellentia foeminei sexus (On the Nobility and Preeminence of the Female Sex) is a work in which Heinrich Cornelius Agrippa develops a forward-thinking argument about the value and role of women in society. This treatise can be considered one of the first feminist writings in modern history.

Agrippa defends the idea that women are not inferior to men but rather possess intellectual and moral qualities that could even make them superior. He uses a variety of cultural, historical, and philosophical references to support his views, citing examples of famous women from history, mythological figures, and saints to show their ability to equal or surpass men in many fields.

The work challenges the gender stereotypes of the time and criticizes the social and religious foundations that keep women in a subordinate position. Agrippa calls for a reevaluation of traditional gender roles, proposing a worldview where women would have the freedom to exercise all virtues and intellectual abilities on equal footing with men.

De incertitudine et vanitate scientiarum

De incertitudine et vanitate scientiarum (On the Uncertainty and Vanity of the Sciences), published in 1530, is another major work by Agrippa where he expresses his growing skepticism toward knowledge and the academic disciplines of his time (which were largely controlled by the Catholic Church at that period).

In this book, Agrippa examines and critiques various branches of science, medicine, law, philosophy, and even theology. He argues that much of what is taught as absolute truth in academic institutions is actually uncertain, prone to error, or fundamentally futile. The text is structured as a series of chapters, each dedicated to criticizing a specific discipline, revealing the limits and contradictions of established knowledge.

Agrippa uses a mix of classical scholarship, philosophical analysis, and irony to demonstrate that so-called knowledge often only masks ignorance or serves the interests of those in power. He advocates for a more humble and questioning approach to learning, suggesting that recognizing our ignorance is the first step toward true wisdom.

The Celestial Alphabet or Agrippa's Cipher

In De Occulta Philosophia, Agrippa explores the concept of sacred languages such as Hebrew and discusses the various ways in which words and names can be used to influence spiritual and physical realities. Thus, the Celestial Alphabet (or Celestial) is composed of characters based on the shapes of constellations, which can be used to transcribe texts in angelic languages or for magical inscriptions. Although it is presented in this work, there is no formal proof that Agrippa is its creator.

This alphabet consists of 22 characters (without vowels) and is presented as a means of communication with divine beings such as angels.

Agrippa's planetary squares

Agrippa's magic squares are among the most intriguing aspects of his writings. This will surely remind you of school memories, but these squares were actually used long before the birth of Cornelius Agrippa, though he adapted and popularized them in occult sciences.

These squares are tables of numbers arranged so that the sum of each column, each row, and each main diagonal is the same, creating a numerical harmony considered magical or mystical.

He assigns each magic square to one of the seven classical planets of astrology, giving them specific attributes and powers according to the associated planet:

Magic squares are engraved on talismans or amulets, each square invoking the corresponding astrological influences such as protection, healing, or the enhancement of certain abilities or circumstances. The idea is that the square, through its order and numerical perfection, attracts and channels the celestial energies of the planet it is associated with.

Agrippa and other occultists of the time saw magic squares as a manifestation of divine order and the structure of the universe. They symbolize harmony and the balance of cosmic forces.
