Who is Thoth?

Thoth is one of the most intellectual figures in the Egyptian pantheon — the god of wisdom, writing, the moon, and magic, scribe of the gods and guarantor of cosmic order. Depicted with an ibis head or in the form of a baboon, he holds the pen of truth during the judgment of souls, calculates the celestial cycles, and invents hieroglyphs — the founding gift of all Nilotic civilisation.

Role, nature and domains

Thoth occupies a unique position in the Egyptian pantheon: he is neither a primordial creator god like Ra, nor strictly a god of the dead like Osiris. He is the intermediary, the mediator, the recorder of all divine and human realities.

His main functions are:

1. Scribe of the gods: Thoth transcribes divine decrees, records judgments, counts the years of pharaohs’ reigns, and inscribes destinies in the books of the sky.
2. Master of the moon: his ibis head crowned with a crescent and lunar disc marks him as the guarantor of the calendar and cosmic cycles.
3. Inventor of writing: hieroglyphs are medu netjer (“words of God”), revealed to mankind by Thoth. This invention is also that of transmissible knowledge, memory, and magic.
4. Guardian of Maat: Thoth is the chief ally of Maat, goddess of truth and cosmic justice — he verifies that weighings are accurate and that accounts are balanced.

Genealogy and origins

Thoth’s genealogy varies across regional traditions. In the Heliopolitan cosmology, he is often presented as a son of Ra — born from the solar god’s head, embodying his speech. In other traditions, he creates himself through the power of his own discourse: the god of divine speech needs no birth to exist — he simply is from the moment language exists.

His main cult centre was Khemenu (Hermopolis Magna, in Middle Egypt), where he was venerated as one of the eight primordial gods of the Ogdoad — the chaotic forces that preceded creation.

Thoth and the Osirian myth

Thoth’s role in the cycle of Osiris is central, though often understated.

After the death of Osiris, it is Thoth who helps Isis and Nephthys reassemble the dismembered body — by reciting the magical formulae (heka) necessary for embalming and for reactivating the ka (vital force). He is the grand master of funerary magic, without whom the Osirian resurrection would be impossible.

Later, during the long conflict between Horus and Seth for the throne of Egypt, Thoth intervenes several times as impartial arbiter: he draws up the acts of the divine tribunal, records the pleadings of the gods, and helps restore Horus’s eye when Seth tears it out.

The judgment of the dead and the weighing of the heart

It is in the Hall of Two Truths that Thoth’s role is most celebrated. During the judgment of souls presided over by Osiris, Thoth stands beside the scales with his reed pen and register.

While Anubis watches the pans of the scale — the deceased’s heart on one side, the feather of Maat on the other — Thoth records the result. If the heart is lighter than the feather, he declares the deceased “true of voice” (maa-kheru) and inscribes his admission to the Fields of Iaru. If the heart is too heavy, Ammit the Devourer consumes the soul — and Thoth records this annihilation as well.

Thoth’s absolute neutrality is his essential attribute in this context: he does not lie, does not interpret, does not falsify. He is divine exactness.

Magic, writing and legacy

The god Thoth is associated with the concept of heka — magic as a primordial cosmic force that precedes the gods themselves in some traditions. Knowing the right words, speaking them in the right order, writing them with precision: that is what Thoth embodies.

The Book of the Dead — the survival guide to the Duat — is sometimes said to have been written by Thoth himself. The magical formulae it contains are presented as revealed divine words.

In the first century BCE, Greco-Egyptian syncretism produced Hermes Trismegistus (“the Thrice-Great”), a composite figure blending Thoth and the Greek Hermes. The Hermetic tradition — a corpus of philosophical and esoteric texts produced between the 1st and 3rd centuries CE — claims this heritage. Western alchemy and Christian Kabbalah would carry its traces through to the Renaissance.

What the ancient sources say

The Pyramid Texts (c. 2400 BCE) already mention Thoth as an assistant to the royal resurrection. The Coffin Texts and the Book of the Dead develop his role in the judgment of souls. The Papyrus of Hunefer (c. 1275 BCE, held in the British Museum) famously depicts the weighing of the heart with Thoth holding his register. The Texts of Hermopolis elaborate his own cosmology as a primordial god.
