Thoth and Hermes are not the same god, but they became connected in late antiquity. Thoth is an ancient Egyptian deity of writing, wisdom, and the moon, while Hermes is an ancient Greek god of messengers, trade, and travelers. The two were merged by Greek-speaking Egyptians into a single figure, Hermes Trismegistus, who became central to Hermeticism and alchemy.
Origins and Cultural Background
Thoth appears in Egyptian records from the earliest dynasties (c. 3000 BCE). He was a self-created god, often depicted with the head of an ibis or as a baboon. His main cult centers were Hermopolis (Khemenu) and Thoth’s temple at that site. Thoth was the scribe of the gods, the inventor of hieroglyphs, and the keeper of divine records. He judged the dead in the Hall of Two Truths and recorded the results of the weighing of the heart.
Hermes, by contrast, is a Greek god whose origins are less clear. He appears in Linear B tablets from the Mycenaean period (c. 1400 BCE) as e-ma-ha. In Homer’s Iliad and Odyssey, Hermes is the son of Zeus and Maia, a messenger, a guide of souls to the underworld, and a cunning trickster. He is also the patron of shepherds, merchants, and thieves. His Roman equivalent was Mercury.
Core Roles and Attributes
Thoth and Hermes share some functions but differ in emphasis. Thoth is primarily a god of intellect, writing, and cosmic order. He is credited with creating the calendar, establishing the laws of Ma’at (truth and justice), and giving humanity the gift of language. In the Pyramid Texts, Thoth is called the “heart of Re” and the “tongue of Atum,” meaning he translates the creator’s will into words.
Hermes is more action-oriented. He is the swift messenger who moves between the mortal and divine realms. He also protects travelers, guides the dead (psychopomp), and brings dreams. In Greek myth, he invents the lyre, steals Apollo’s cattle, and negotiates with the Fates. He is clever and playful, whereas Thoth is solemn and wise.
The Syncretism of Thoth and Hermes
The blending of Thoth and Hermes began in the Ptolemaic period (after 332 BCE), when Greek and Egyptian cultures interacted in Alexandria. Greeks recognized similarities between Thoth and Hermes: both were messengers, both were associated with writing (Hermes was linked to the invention of the alphabet), and both had roles in the afterlife. The Greek historian Herodotus (5th century BCE) already equated Thoth with Hermes, calling him “Hermes the Thrice-Great” (Hermes Trismegistus).
The name “Trismegistus” (thrice-great) comes from the Egyptian epithet aa aa aa (great, great, great) applied to Thoth. Over time, Hermes Trismegistus became a legendary sage, the author of a body of texts known as the Hermetica. These texts, written in Greek and Coptic between the 1st and 3rd centuries CE, blend Platonic philosophy, Egyptian religion, and Gnostic ideas. They teach that humanity can attain divine knowledge (gnosis) and that the cosmos is a living, divine being.
How They Differ in Mythology and Worship
Thoth was a major state god in Egypt. He was invoked in rituals, and his priests at Hermopolis developed a complex theology. Thoth was also a moon god, which linked him to time and measurement. He was said to have won five extra days in the year by gambling with the moon, allowing the goddess Nut to give birth to her children. This myth explains the 365-day calendar.
Hermes was a more popular, everyday god in Greece. He was honored at crossroads, where herms (stone pillars with his head and genitals) were placed. He was also a god of gymnasiums and athletics. Unlike Thoth, Hermes had no major priesthood or temple cult; he was worshipped in homes and at boundary markers. His myths focus on his cleverness and his role as a mediator.
Hermes Trismegistus and Hermeticism
The figure of Hermes Trismegistus is a composite. He is not the Greek Hermes nor the Egyptian Thoth, but a new entity created by Greco-Egyptian intellectuals. The Corpus Hermeticum is a collection of 17 Greek treatises attributed to him. The most famous is the Poimandres, a vision of the divine mind. These texts were later translated into Latin in the Renaissance, influencing thinkers like Marsilio Ficino and Giordano Bruno.
Hermeticism also gave rise to alchemy, astrology, and magic. The Emerald Tablet, a short text attributed to Hermes Trismegistus, contains the famous phrase “As above, so below.” This principle influenced Western esotericism for centuries. Note that the Emerald Tablet is a medieval Arabic work, not an ancient Egyptian text, but it is part of the Hermetic tradition.
Common Misconceptions
A frequent error is to treat Thoth and Hermes as interchangeable. While they were syncretized, they remained distinct in their original cultures. Thoth never had Hermes’ role as a thief or a god of trade. Hermes never had Thoth’s role as a judge of the dead or a creator of language. Another misconception is that Hermes Trismegistus was a real person. He is a mythical figure, a personification of wisdom, not a historical sage.
Also, the Greek Hermes is not the same as the Roman Mercury, though they were equated. Mercury was originally a god of commerce and travel, and his attributes were later merged with Hermes’. In art, Mercury is often shown with a purse, while Hermes is not.
Frequently Asked Questions
Are Thoth and Hermes the same god?
No. Thoth is an Egyptian god, Hermes is a Greek god. They were syncretized in the Greco-Roman period as Hermes Trismegistus, but they have different origins, myths, and roles.
Why is Hermes called Thoth?
Hermes is not called Thoth. The Greeks identified Thoth with Hermes because of similarities in their functions. The resulting figure, Hermes Trismegistus, was often referred to as “Thoth” in Egyptian contexts, but this is a later interpretation.
What is the Emerald Tablet?
The Emerald Tablet is a short text attributed to Hermes Trismegistus. It is a foundational document of alchemy, containing the maxim “As above, so below.” It was likely written in Arabic in the 8th or 9th century CE, not in ancient Egypt.
Did Thoth invent writing?
In Egyptian mythology, Thoth is credited with inventing hieroglyphs and being the scribe of the gods. The Greeks similarly credited Hermes with inventing the alphabet, but this is a later attribution.
Who is the Greek god of wisdom?
Athena is the Greek goddess of wisdom, not Hermes. Hermes is a god of intelligence and cunning, but wisdom in the sense of strategic warfare and crafts belongs to Athena. Thoth is the Egyptian god of wisdom.
Is Hermes Trismegistus a real person?
No. Hermes Trismegistus is a legendary figure, a syncretic deity combining Thoth and Hermes. He is not a historical person, but a mythical sage to whom many esoteric texts were attributed.
Conclusion
Thoth and Hermes are distinct deities from two different pantheons. Their fusion into Hermes Trismegistus was a product of cultural exchange in the Hellenistic world. Understanding their original roles helps clarify why they were merged and what each god contributed to the Hermetic tradition. If you are studying mythology, keep them separate; if you are studying esotericism, you will meet them together.
