Imagine a woman standing at the edge of the sea after the Flood, watching the water rise. She is the last of her kind, the one who loved a fallen angel. The Book of Enoch says she did not drown. She became a siren.
In the Book of Enoch, the beings later called mermaids are the transformed spirits of the human women who consorted with the fallen Watchers, condemned to become aquatic temptresses. This is one of the earliest surviving references to half-human, half-fish creatures in a Near Eastern religious context, predating the medieval mermaid folklore by over a millennium. The text is specific: the women did not die but were changed into sirens, an eternal punishment for their transgression.
The Book of Enoch describes mermaids as the transformed women who mated with fallen angels. Learn the history, symbolism, and occult significance of these sirens of the Watcher tradition.
Where does the Book of Enoch mention mermaids?
The passage is short and dense. In 1 Enoch 19:2, the text states: “And the women also of the angels who went astray shall become sirens.” The verse is part of the Book of the Watchers (chapters 1–36), the oldest section of the Enochic corpus, composed between 300 and 200 BCE. The prophet Enoch is shown the judgment of the fallen angels and their human wives. The fate of the women is distinct: they are not killed by the Flood and do not receive the same punishment as the giants. Instead, they are transformed into creatures that dwell in the waters.
The Greek text of 1 Enoch, preserved in the Akhmim codex (5th–6th century CE), uses the word seirenes (sirens). The Ethiopic version, which is the most complete, uses mäwa’el, a term that can mean both “siren” and “mermaid” in the Ethiopian tradition. The Aramaic fragments from the Dead Sea Scrolls (4QEn) do not contain this verse, so the original wording is uncertain. But the Greek and Ethiopic witnesses agree on the core meaning: the women became sirens.
This is the only place in the Book of Enoch where such creatures are named. The text does not describe their physical form. It does not say they have fish tails. The term “siren” carried its own mythological baggage from the Greek tradition, which the translators of Enoch would have known. For the Ethiopian Orthodox Church, which canonized the Book of Enoch, these mäwa’el are real spirits that inhabit the sea, often hostile to humans.
The Watchers and the Sirens: A history of the text
The Book of Enoch was widely read in Second Temple Judaism. Fragments of the Aramaic original were found among the Dead Sea Scrolls, confirming its importance to the community at Qumran. Early Christians also knew it: the Epistle of Jude quotes Enoch directly (Jude 14–15), and the church fathers Clement of Alexandria and Tertullian cited it as scripture. But by the fourth century, the rabbinic tradition rejected it, and the Western Church gradually excluded it from the canon. The text survived in full only in the Ethiopian Orthodox canon, where it remains to this day.
The Greek version of Enoch, which contains the siren passage, was translated from the Aramaic sometime in the first century BCE or CE. The Greek translators used seirenes because that was the closest term in their culture for a hybrid creature that lured men to destruction. Homer’s sirens were bird-women, but by the Hellenistic period they were also associated with the sea. The translator’s choice shaped how the Enochian sirens were understood for centuries.
The first European to bring the complete Ethiopic text to the West was the Scottish explorer James Bruce in 1773. He returned with three manuscripts of the Book of Enoch, and the first English translation was published in 1821 by Richard Laurence, then a professor of Hebrew at Oxford. Laurence’s translation rendered mäwa’el as “sirens,” and his footnote explained that these were “mermaids” in the popular imagination. That note is the bridge between the ancient text and the modern occult concept of the Enochian mermaid.
For the Ethiopian Christians who preserved the text, the meaning was concrete. The women of the Watchers were not allowed to die. They were transformed into water spirits, a punishment that made them permanent outsiders to both the human and angelic realms. The consequence for ordinary believers was clear: the sea was dangerous not only because of storms but because of the spirits of women who had once loved angels.
What do the Enochian sirens represent?
The sirens of the Book of Enoch are symbols of transgression and its irreversible cost. They represent the point where human desire meets divine law and breaks. The women actively chose to mate with the Watchers, and their punishment is to become a permanent temptation to others. The siren’s song is the echo of that original sin.
On a deeper level, the sirens embody the liminal state. They are no longer human, not fully animal, not quite demon. They live in the water, the boundary between the living world and the underworld. In the Enochic cosmology, the waters of the deep are where the fallen angels were chained (1 Enoch 10:4–6). The sirens share that domain. They are a warning that love across the boundary between the human and the divine carries a price that cannot be paid back.
The sirens also carry the weight of the forbidden knowledge that the Watchers taught. The Watchers revealed the secrets of heaven to humanity: metallurgy, cosmetics, astrology, magic. The women who received that knowledge directly were not allowed to return to ordinary life. Their transformation into sirens is a kind of preservation: they are frozen in the moment of their transgression, forever singing the song of the knowledge they gained.
How occultists work with the Enochian sirens
The Enochian sirens have a place in contemporary esoteric practice, though they are not as prominent as the Watchers themselves. They appear in traditions that draw on the Book of Enoch for spirit classification and ritual invocation.
In some modern Enochian magic systems, the sirens are considered a class of spirits of the water or air, associated with the element of water and the south-western quadrant of the Watchtowers. They are invoked for divination, dream work, and the uncovering of hidden knowledge. But the tradition is cautious. The sirens are not neutral. They are cursed beings, and their default relationship with humans is one of deception.
Practitioners who work with the Enochian sirens often approach them as threshold guardians. They are called upon at the start of a ritual that involves crossing between worlds, because the sirens themselves live in the space between. The offering is typically silver or something that reflects light, and the water is always fresh water, not salt. The salt sea is the domain of the Watchers themselves, and the sirens are said to avoid it.
We should note that the Enochian sirens are distinct from the Oannes or the Babylonian water gods. They are not deities. They are transformed humans, and the ritual relationship is one of negotiation with a fallen spirit, not worship. The practitioner who calls them must be prepared to hear what they have to say, because the sirens speak the truth of the Watchers, and that truth is not comforting.
The Enochian siren and its Greek counterpart
The Greek sirens of Homer are bird-women who sing sailors to their deaths. The Enochian sirens are transformed women, but the two traditions are not the same. The Greek sirens are daughters of the river god Achelous and the muse Melpomene, semidivine beings from the start. The Enochian sirens were once ordinary human women. They became sirens as a punishment, not by birth.
The overlap comes from the Greek translation of Enoch. The translator chose seirenes because it was the closest available word for a creature that combined human features with a non-human body and used song to lure. But the original Enochic concept may have been closer to the Mesopotamian lilith (a night spirit) or the kudurru (a boundary demon). The Aramaic word that underlies mäwa’el is lost, but it likely meant something like “water spirit” or “howling thing.”
Later Western occultists, reading the Laurence translation, conflated the two. The Enochian siren became a mermaid in the popular imagination, complete with a fish tail. But the text never describes a tail. The Enochian sirens are spirits without a fixed form, and the fish tail is a later addition from medieval folklore.
The difference matters for the practitioner. The Greek siren is a mythological creature that belongs to poetry. The Enochian siren is a theological entity that belongs to a system of judgment and punishment. They are not interchangeable.
Common misconceptions about the Enochian mermaid
Misconception: The Book of Enoch is part of the Bible. It is not. It is canon in the Ethiopian Orthodox Church, but most Christian denominations and Jewish traditions do not include it. It is considered pseudepigrapha.
Misconception: The Enochian mermaids are benevolent water spirits. The text is clear: they are the result of a curse. They are dangerous and deceptive. They are not the healing mermaids of modern folklore.
Misconception: The Book of Enoch describes mermaids with fish tails. The text does not describe their physical form at all. The fish tail is a later conflation with Greek and medieval mermaid imagery.
Misconception: The Enochian sirens are the same as the Greek sirens. They are not. The Greek sirens are semidivine beings; the Enochian sirens are transformed humans. The similarity is limited to the translation terminology.
Misconception: The Book of Enoch is a single unified text. It is a collection of five books, written over several centuries. The siren passage is in the oldest section, the Book of the Watchers.
