Hermeticism, also called Hermetism, is a philosophical and religious tradition based on teachings linked to Hermes Trismegistus, a figure who combines aspects of the Greek god Hermes and the Egyptian god Thoth. This tradition includes secret knowledge from areas like alchemy, astrology, and theurgy, and has influenced many mystical and occult traditions over time. The writings connected to Hermes Trismegistus, known as the Hermetica, were created over many centuries (about 300 BCE to 1200 CE) and may vary greatly in content and scope.

A specific type of Hermetic teaching is found in a group of writings called the "religio-philosophical" Hermetica. The most well-known works in this group are the Corpus Hermeticum, a collection of seventeen Greek texts written between about 100 and 300 CE, and the Asclepius, a text from the same period that mostly survives in a Latin version. This form of Hermetic philosophy is sometimes called Hermetism to distinguish it from other systems inspired by Hermetic writings from different times.

The term Hermeticism can refer to many different philosophical systems that use Hermetic writings or other ideas connected to Hermes. For example, alchemy was often called "the Hermetic art" or "the Hermetic philosophy." A famous example of this broader use is Renaissance Hermeticism, which includes early modern ideas inspired by translations of the Corpus Hermeticum by Marsilio Ficino (1433–1499) and Lodovico Lazzarelli (1447–1500). It also includes the medical ideas of Paracelsus (1494–1541), who used writings like the Emerald Tablet.

Throughout history, Hermeticism has been linked to the belief in ancient, divine wisdom shared only with the earliest wise people, such as Hermes Trismegistus. During the Renaissance, this idea became known as "prisca theologia" or "ancient theology," which claimed that a single true theology was given by God to the first humans and that parts of it remained in ancient systems of thought. This idea, supported by thinkers like Giovanni Pico della Mirandola (1463–1494), led to the belief that divine truth could be found in many religious and philosophical traditions. This idea became known as the "perennial philosophy." Over time, the word "Hermetic" became less specific, eventually being used to describe the divine knowledge of ancient Egypt, especially as it relates to alchemy and magic. This view was later promoted by occultists in the 19th and 20th centuries.

Origins and early development

In Late Antiquity, Hermetism began in Hellenistic Egypt, a time when Greek, Egyptian, and other Near Eastern religious and philosophical traditions blended together. The central figure of Hermes Trismegistus, who combined the Greek god Hermes and the Egyptian god Thoth, became a symbol of this blending of cultures. Hermes Trismegistus was honored as a wise teacher and is known for a large collection of writings called the Hermetica, which discuss theology, the universe, and spiritual practices.

Hermetism grew at the same time as other important religious and philosophical movements, such as early Christianity, Gnosticism, Neoplatonism, the Chaldean Oracles, and late Orphic and Pythagorean writings. These movements focused on ideas that were not strictly based on reason or strict religious beliefs. Plutarch, a writer from the first century CE, mentioned Hermes Trismegistus, showing that this figure was recognized in Greek and Roman thought. Other important thinkers of the time, like Tertullian, Iamblichus, and Porphyry, were also familiar with Hermetic writings, which influenced their own ideas.

The texts now called the Corpus Hermeticum are usually believed by modern scholars to have been written in the early second century or earlier. These writings describe the unity and goodness of God, the purification of the soul, and the connection between the mind and spirit. They are mostly written as dialogues, where Hermes Trismegistus teaches a confused student about hidden wisdom.

In fifth-century Macedonia, a writer named Joannes Stobaeus collected many Greek writings, including poetry, speeches, history, and philosophy. Among these, many dialogues and teachings attributed to Hermes Trismegistus were preserved.

Hermeticism greatly influenced early Christian thought, especially in the development of Christian mysticism and secret interpretations of religious texts. Some early Christian leaders, like Lactantius, saw Hermes Trismegistus as a wise non-Christian prophet whose ideas were compatible with Christianity. The Hermetic belief in a distant, unknowable God who created the universe through a process of creation matched ideas held by early Christian thinkers who wanted to connect their faith with classical philosophy.

However, Hermeticism had the strongest influence on Gnostic traditions, which shared a focus on secret knowledge as the path to salvation. Both movements taught that the soul's true home was in the divine realm, and that the physical world was a place of separation, though Hermeticism viewed the material world more positively. The Hermetic idea of rising through knowledge and purification was similar to Gnostic teachings about the soul's journey back to its divine origin, linking these two esoteric traditions.

Core texts

The Hermetica is a group of writings believed to be written by Hermes Trismegistus. These writings are the main source of the Hermetic tradition. They were created over many years, mainly during the Hellenistic, Roman, and early Christian times, from about 200 BCE to 300 CE. The Hermetica is usually divided into two parts: the philosophical or theological Hermetica, and the technical Hermetica, which includes topics like alchemy, astrology, and other mystical studies.

The most well-known and important part of the philosophical Hermetica is the Corpus Hermeticum. This collection has seventeen writings that explain the main ideas of Hermeticism. These writings are mostly dialogues where Hermes Trismegistus teaches a student about secret knowledge, covering topics like the nature of the divine, the universe, the soul, and the path to spiritual growth. Important texts in the Corpus Hermeticum include Poimandres, which describes the universe and humanity’s place in it, and Asclepius, which discusses theurgy, magic, and the divine spirit in all things.

Another important text in the Hermetica is the Emerald Tablet. This short work is very important in Western alchemy. Though its origins are unclear, the Emerald Tablet includes the Hermetic idea of "as above, so below," meaning there is a connection between the universe (macrocosm) and the individual soul (microcosm). The Emerald Tablet has been studied and explained many times, and it greatly influenced alchemy during the Middle Ages and the Renaissance.

The technical Hermetica includes writings about astrology, alchemy, and theurgy. These were seen as ways to understand and work with divine forces in the world. These texts had a major impact on the Western esoteric tradition, helping medieval alchemists, astrologers, and others in their studies.

Other important original Hermetic texts include Isis the Prophetess to Her Son Horus, which is a long conversation between Isis and Horus about the fall of humans and other topics; The Definitions of Hermes Trismegistus to Asclepius; and many pieces that are mainly kept in a collection by Stobaeus.

The way the Hermetica was shared and understood played a key role in its influence on Western thinking. During the Renaissance, these texts were found again and translated into Latin, causing a renewed interest in Hermetic ideas. Translations by Marsilio Ficino and Lodovico Lazzarelli were especially important, as they introduced Hermetic ideas to Renaissance scholars and helped shape early modern esotericism.

Renaissance thinkers like Giovanni Pico della Mirandola and Giordano Bruno saw Hermeticism as a source of ancient wisdom that could be combined with Christian teachings and classical philosophy. The Hermetic belief in the divine nature of humans and the possibility of spiritual growth matched the Renaissance idea of human value and the search for knowledge.

Over time, the Hermetica has been interpreted in many ways, from philosophical and mystical views to practical uses in alchemy and magic. The secret nature of these texts has allowed them to be adapted to different cultures and times, making them influential for many centuries.

Philosophical and theological concepts

In the religious and philosophical writings called the Hermetica, the ultimate reality is described using many names, such as God, Lord, Father, Mind (Nous), the Creator, the All, the One, and others. According to Hermetic teachings, God is both the source of all things (called "the All" in Greek: to pan) and the creator of everything. All things that exist were already present in God before they were made, and God is the nature of the universe itself. God is the material from which the universe is formed and the guiding force that shapes it. However, the universe and everything in it were created by God. This means God creates itself and exists both beyond the universe (transcendent) and within it (immanent). These ideas are similar to the views of the Stoics, who also believed in the unity of the universe and its divine source.

In Hermeticism, "prima materia" is an important idea in alchemy. It refers to the raw, unformed substance from which all things are made. This substance is often linked to "chaos," a state of formlessness and potential that comes before creation. The concept of prima materia has roots in ancient Greek and Roman traditions, such as the Orphic belief in the "cosmic egg," and in the biblical story of "Tehom" from Genesis. These connections show how Hermetic ideas blended classical and Christian thought during the Renaissance.

In alchemy, prima materia is the substance that changes through processes like "nigredo," a stage marked by darkness and chaos. This transformation leads to the creation of the "philosopher's stone," a symbol of the alchemist's goal to purify and perfect matter. Renaissance thinkers like Paracelsus expanded on this idea, connecting it to the elements and the Hermetic belief that matter and spirit are united.

The importance of prima materia in Hermeticism is its role in showing the possibility of both physical and spiritual change. It reflects the Hermetic principle "as above, so below," meaning the universe (macrocosm) and the individual (microcosm) mirror each other in the alchemical process.

Hermeticists believe in "prisca theologia," the idea that a single true theology exists in all religions and was revealed by God to humans in ancient times. Early Christian thinkers, such as Lactantius and Augustine, referenced Hermes Trismegistus, sometimes describing him as a wise pagan prophet whose teachings could support Christian beliefs.

During the Renaissance, scholars like Marsilio Ficino and Giovanni Pico della Mirandola tried to combine Hermetic teachings with Christian theology. They saw Hermetic writings as remnants of an ancient wisdom that influenced all religions, including Christianity. These scholars also linked Hermes Trismegistus to biblical figures like Moses or to a lineage including Enoch and Noah, helping to connect Hermetic ideas with Christian stories.

The phrase "as above, so below" is a modern version of a line from the Emerald Tablet, a short and mysterious text attributed to Hermes Trismegistus. The original Latin version reads: "That which is above is like to that which is below, and that which is below is like to that which is above."

In addition to "prisca theologia" and "as above, so below," Hermeticism teaches that the soul's journey back to the divine involves passing through the seven heavens. These heavens are linked to the seven classical planets and represent stages of spiritual growth. As the soul moves through each level, it leaves behind material influences and becomes closer to the divine. This process shows the soul's return to its divine origin, aiming to unite with "The One," the source of all existence.

In the first book of the Corpus Hermeticum, God tells Hermes a story of creation. God creates the primary matter that forms the universe. From this matter, God separates the four elements: earth, air, fire, and water. Then, "The Word" (Logos) emerges from the elements, which were not yet intelligent. Nous (Mind) then causes the seven heavens to rotate, and creatures without speech appear. Earth is separated from water, and animals (other than humans) are created. God then arranges the elements into the seven heavens, often associated with the spheres of Mercury, Venus, Mars, Jupiter, Saturn, the Sun, and the Moon. These spheres are believed to govern destiny. God creates humans in His own image and gives them authority over all creation.

Humans observe the creation of Nous and receive the power to rule over all things. They rise above the heavens to see creation clearly. Humans then reveal the form of the All to Nature, which falls in love with the All. Humans, seeing their reflection in water, fall in love with Nature and choose to live within it. As a result, humans become one with Nature and are bound by its limits, such as sleep and sex. Humans lose "The Word" and become "double," having a mortal body but an immortal spirit. They retain authority over creation but are now subject to fate.

Another version of the fall of humans, found in the story of Isis to her son Horus, describes how God created souls from a mysterious substance and sent them to Earth to create life. These souls became proud and wanted to be equal to the gods, angering God. As punishment, God ordered Hermes to give the souls physical bodies. Souls were told that their time on Earth would involve suffering, but if they lived worthily, they could return to the heavens. If not, they would be reborn repeatedly on Earth.

In Book 9 of the Corpus Hermeticum, Hermes explains that Nous (reason and knowledge) can produce either good or evil, depending on whether humans receive their understanding from God or from demons. God brings good, but demons bring evil. Examples of evil actions include adultery, murder, and other harmful deeds.

The word "good" is used strictly to refer to God. Only God (in the sense of Nous, not the All) is completely free from evil. Humans are not good because their physical nature distracts them from the Supreme Good. Asclepius explains that evil comes from desire, which is caused by ignorance. However, the intelligence given by God allows some people to overcome desire.

Focusing too much on material life is said to anger God. Just as people walking in a road do not achieve anything but block others, humans who are driven by physical pleasures move through the universe without purpose. To honor God, humans must create and do positive things in their lives.

Historical development

In the late Middle Ages and early Renaissance, a few Hermetic occult groups were formed. In England, these groups became connected to the Lollard-Familist traditions.

The word "Hermetic" comes from "Hermeticus," a Latin word from the medieval period. It is based on the name of the Greek god Hermes and refers to secret writings and practices linked to Hermes Trismegistus. This term was often used to describe the "Hermetica," a collection of texts believed to contain hidden knowledge about the divine, the universe, and the human soul.

The English word "Hermetic" first appeared in the 17th century. One of the earliest uses was in John Everard’s translation of The Pymander of Hermes, published in 1650. The term was used to describe "Hermetic writers" like Robert Fludd. The word "Hermetical" also appeared in Sir Thomas Browne’s Religio Medici (1643), where it referred to scholars and alchemists who studied the natural world using Hermetic ideas.

The phrase "hermetically sealed" comes from alchemy and describes a method of tightly sealing containers in labs. Over time, the term became a metaphor for protecting secret knowledge, meaning such wisdom should remain hidden from those not ready to understand it.

The word "Hermetic" later came to mean something mysterious, hidden, or hard to understand. This reflects the idea in Hermeticism that sacred knowledge should be kept secret from those unprepared to receive it.

Hermeticism greatly influenced the Western esoteric tradition. After being forgotten for centuries, it was reintroduced in 1460 when Leonardo di Pistoia brought the Corpus Hermeticum to Pistoia. He was sent by Cosimo de’ Medici, who wanted to find ancient writings in European monasteries. Scholars like Giovanni Pico della Mirandola helped make Hermeticism more understandable during the Renaissance by connecting it to Jewish and Christian mysticism.

In 1614, Isaac Casaubon, a Swiss scholar, studied Greek Hermetic texts and concluded they were written in the second and third centuries CE, not by an ancient Egyptian priest. Despite this, Thomas Browne in Religio Medici (1643) still believed in Hermetic philosophy, saying, "The severe schools shall never laugh me out of the philosophy of Hermes, that this visible world is but a portrait of the invisible."

In 1678, Ralph Cudworth pointed out flaws in Casaubon’s dating, arguing that only three of the seventeen texts in the Corpus Hermeticum were likely forgeries. He also noted that the texts were based on an older oral tradition.

In 1964, Frances A. Yates argued that Renaissance Hermeticism played a key role in the development of modern science. Though her ideas are now mostly rejected, the influence of Hermetic alchemy on scientists like Jan Baptist van Helmont, Robert Boyle, and Isaac Newton is well-documented.

Rosicrucianism is a movement that includes Hermetic ideas. It began in the 17th century and is linked to three German pamphlets: The Fama, The Confessio Fraternitatis, and The Chymical Wedding of Christian Rosenkreutz. Some scholars think these pamphlets were hoaxes, and actual Rosicrucian groups appeared later.

Hermetic magic was revived in the 19th century in Western Europe. It was practiced by groups like the Hermetic Order of the Golden Dawn and individuals such as Eliphas Lévi, William Butler Yeats, and Arthur Machen. The book The Kybalion, published in 1908 by three people called "The Three Initiates," explains key Hermetic principles.

In 1924, Walter Scott dated Hermetic texts to shortly after 200 CE, while W. Flinders Petrie suggested they were written between 200 and 500 BCE.

In 1945, Hermetic texts were discovered near Nag Hammadi, Egypt. One text was a conversation between Hermes and Asclepius. Another, titled On the Ogdoad and Ennead, described Hermetic mystery schools and was written in Coptic, the final form of the Egyptian language.

Gilles Quispel claimed that a secret society existed in Alexandria before and after the start of the Christian era, similar to a Masonic lodge. Christian Bull, however, argued there is no evidence for such a group in ancient times.

Geza Vermes said Hermeticism was a Hellenistic mysticism that existed around the same time as the Fourth Gospel. He described Hermes Trismegistus as a version of the Egyptian god Thoth, who was believed to give wisdom through knowledge (gnosis).

The Hermetic Order of the Golden Dawn was a group that taught alchemy, qabalah, and Hermetic magic. It was active in the late 19th and early 20th centuries and allowed both men and women to join equally. Arthur Edward Waite, a leader of the Golden Dawn, wrote books about Hermeticism and helped add the word "Hermetic" to the group’s official name.

The Golden Dawn kept its secrets very closely, with strict rules against sharing them. Most people outside the group knew little about it. Aleister Crowley and Israel Regardie later revealed details about the Order to the public.

After the Renaissance and into the 20th century, scholars studied Hermeticism less than other topics. However, interest in Hermeticism grew again in the 1990s.

Hermetic practices

The phrase "The three parts of the wisdom of the whole universe" comes from the Emerald Tablet and refers to three areas of study in Hermeticism. Hermetic practices are based on ancient mystical traditions that include alchemy, astrology, theurgy, and other spiritual disciplines. These practices are not only about rituals but also aim to help people grow spiritually, connect with the divine order, and learn more about themselves and the universe.

Alchemy, also called the "operation of the Sun," is one of the most famous Hermetic practices. Many people think of alchemy as an early attempt to turn metals like lead into gold, but in Hermeticism, alchemy is mainly a spiritual path. The physical changes in materials during alchemy symbolize the spiritual growth and purification of the soul. The main goal of alchemy is to create the philosopher's stone, which represents spiritual enlightenment and immortality. Alchemy is not just about changing lead into gold (a process called chrysopoeia). Instead, it explores the spiritual nature of matter and the universe through ideas like birth, death, and resurrection.

The alchemical process has several stages, such as nigredo (blackening), albedo (whitening), and rubedo (reddening). Each stage represents a different step in spiritual growth and understanding. A key concept in alchemy is the "prima materia," which is the original substance from which all things are made. Steps like chemical distillation and fermentation are part of the alchemical process, helping to transform the prima materia into the philosopher's stone. This transformation allows the alchemist to unite with the divine and understand their true spiritual nature. This final goal is called the "Great Work" (Latin: magnum opus).

In Hermetic astrology, the positions and movements of planets and stars are not just studied for their effect on people but are seen as reflections of the divine order of the universe. These celestial patterns are believed to show the will of the divine and the structure of the cosmos. Hermetic astrology helps people align their lives with the divine plan and also determines the best times for rituals and alchemical work. Astrology is said to have been discovered by Zoroaster, who is credited with sharing this part of the wisdom of the whole universe with humans.

Theurgy is a practice that involves calling upon divine powers to purify the soul and help it ascend to higher spiritual realms. Unlike magic that affects the physical world, theurgy focuses on connecting with the divine. Through theurgy, Hermetic practitioners aim to unite their souls with higher spiritual realities and eventually reach unity with the divine source, called "The One." This practice may include using sacred names, symbols, or taking on divine forms. In some forms of Hermeticism influenced by Christian Kabbalah, theurgy relies on a spiritual hierarchy of angels, archangels, and the names of God.

The word "theurgy" means "the science or art of divine works" and is closely linked to alchemy in Hermeticism. Alchemy is considered the key to theurgy, and the ultimate goal of theurgy is to unite with higher spiritual beings and achieve divine consciousness.

Hermetic Qabalah is a version of Jewish Kabbalistic teachings adapted for Western mystical traditions. It helps Hermetic practitioners understand the relationship between the divine, the universe, and themselves. A central symbol in Hermetic Qabalah is the Tree of Life, which shows the structure of creation and the path to spiritual growth. The Tree has ten spheres, called sephiroth, each representing different aspects of the divine and stages of spiritual development.

Hermetic Qabalah combines alchemical, astrological, and theurgical ideas into a single system. By studying and using Qabalistic principles, Hermetic practitioners aim to gain self-knowledge, achieve spiritual enlightenment, and ultimately unite with the divine.

Hermeticism and other religions

Hermeticism has affected and been affected by major religious traditions, especially Judaism, Christianity, and Islam. During the Renaissance, Christian scholars such as Marsilio Ficino included Hermetic teachings in Christian theology, believing these ideas were ancient wisdom that matched Christian beliefs. This led to the creation of a version of Hermeticism adapted to Christianity, which viewed Hermes Trismegistus as a figure connected to early Christian knowledge.

Jewish philosophy and Jewish mystical traditions formed the foundation of Hermetic Qabalah, which combined Hermeticism with Kabbalah, the main mystical part of Judaism. Qabalah brought together Hermetic ideas, such as the Law of Correspondence, with Kabbalistic concepts like the Tree of Life and the Sefirot. Hermetic Qabalah greatly influenced Western mystical traditions, shaping many spiritual movements and philosophical ideas within the broader mystical field.

Islamic mysticism, especially Sufism, and Islamic alchemy were influenced by Hermeticism. Islamic scholars kept and shared Hermetic writings, incorporating them into Islamic philosophy and spiritual practices.

Criticism and controversies

Hermeticism, like other secret traditions, has been criticized and discussed a lot over time, especially about where it came from, if it's real, and its role today.

Scholars have debated whether the Hermetic texts, such as the Corpus Hermeticum, are truly ancient writings or if they were created later by combining ideas from Greek, Egyptian, and other cultures. Experts disagree about when these texts were written, with some saying they date to the early centuries CE and others believing they are even older.

Another topic of discussion is the figure of Hermes Trismegistus. Traditionally, this name was thought to represent an ancient wise person or a mix of the Greek god Hermes and the Egyptian god Thoth. However, many modern scholars believe Hermes Trismegistus is more of a symbol for a type of knowledge rather than a real person. This has led to questions about whether Hermeticism is a clear tradition or a collection of loosely connected ideas.

Today, some spiritual and occult groups, like the Hermetic Order of the Golden Dawn, use Hermetic teachings in their practices. However, others argue that these groups often mix Hermetic ideas with other traditions, which may change or confuse their original meaning.

Hermeticism’s focus on personal spiritual understanding and its unclear connection to traditional religious beliefs have also caused some religious groups to criticize it. These groups often see Hermeticism as a form of occultism that moves people away from established religious teachings.

Legacy and influence

Hermeticism has had a major influence on Western thought, shaping many mystical beliefs, philosophical ideas, and cultural expressions. Its effects can be seen from the Renaissance, when Hermetic writings were rediscovered, to modern times, where its ideas appear in esoteric traditions and popular culture.

Hermeticism is a key part of Western mystical traditions, with its teachings deeply connected to various occult and spiritual beliefs. During the Renaissance, scholars such as Marsilio Ficino and Giovanni Pico della Mirandola helped reintroduce Hermetic ideas into Christian theology and philosophy. This revival helped create later mystical traditions, including Rosicrucianism, Freemasonry, and the Hermetic Order of the Golden Dawn.

The Hermetic idea that "as above, so below" and the belief that all true knowledge and religion come from an ancient source became central to these traditions. Hermeticism’s focus on personal spiritual growth and the search for hidden knowledge continues to affect modern groups, such as Thelema, started by Aleister Crowley, and practices like alchemy, astrology, and magic.

Hermeticism also influenced literature, art, and popular culture. Symbols and themes from Hermetic writings inspired many writers, artists, and thinkers. For example, works by William Blake, Johann Wolfgang von Goethe, and Jorge Luis Borges include ideas from Hermetic philosophy, such as spiritual growth, divine knowledge, and the connection between all things.

In modern literature, Hermetic themes appear in books by authors like Umberto Eco, John Crowley, and Dan Brown, who write about secret knowledge, hidden societies, and the mystical links between small and large parts of the world. Symbols like the caduceus of Hermes and the philosopher’s stone are also common in movies, TV shows, and video games, representing mystery, power, and change.
