The Book of Giants is an ancient Jewish text, composed in Aramaic probably in the second century BC, that retells the fall of the Watchers from a startling angle: through their monstrous sons, the giants. No complete copy survives anywhere. It is known from fragments of as many as ten manuscripts found among the Dead Sea Scrolls, and from scraps of the rewritten version that the prophet Mani canonized as scripture for his own religion — and it is the only ancient Jewish text known to mention Gilgamesh by name.
Of all the lost books orbiting the Bible, few have a stranger biography. The Book of Giants was popular enough at Qumran to be copied again and again, vanished so completely that no medieval library preserved it, resurfaced in the twentieth century in two places thousands of miles apart — a desert oasis on the Silk Road and the caves above the Dead Sea — and turned out to contain the name of the most famous hero of Mesopotamian legend. This guide covers what the book is, the story its fragments tell, how it survived, and why it never entered any Bible.
The Book of Giants belongs to the family of Enochic literature — ancient Jewish writings composed under the name of Enoch, the patriarch of Genesis 5 who "walked with God." Like the rest of that family, it is a pseudepigraphon: a work attributed to a revered ancient figure by later authors, a common and accepted literary convention in the Second Temple period.
Where 1 Enoch tells the story of the fallen angels largely from heaven's point of view — the rebellion, Enoch's commissioning, the decree of judgment — the Book of Giants turns the camera around. Its protagonists are the giants themselves: named, quarrelsome, violent, and increasingly terrified as ominous dreams warn them of the flood to come. It reads less like an apocalypse and more like a doomed family drama.
The book was clearly valued by the community that kept the Dead Sea Scrolls: by most counts, fragments of nine or ten separate manuscripts turned up at Qumran, which is more copies than survive there of several books that did make it into the Bible. The scrolls scholar J. T. Milik even proposed that the Book of Giants once stood inside an early collection of Enochic works, in the slot later occupied by the Book of Parables. That remains a hypothesis, but it captures how central the book once was to the Enoch tradition.
The backstory comes from Genesis 6 and its great ancient expansion, the Book of the Watchers (1 Enoch 1–36). Two hundred angels called Watchers descend on Mount Hermon, bind themselves by oath, take human wives, and teach forbidden arts. Their wives bear giants — the Nephilim of Genesis, the verse behind the whole tradition: "There were giants in the earth in those days" (Genesis 6:4, KJV). The giants devour the produce of the earth, then the animals, then turn on humanity itself, until the earth cries out and God decrees the flood.
1 Enoch tells that story in a few brisk chapters and moves on to Enoch's heavenly journeys. The Book of Giants stays on the ground. It gives the giants names — Ohya and Hahya, sons of the chief Watcher Shemihazah; Mahaway, son of the Watcher Baraqel; Gilgamesh; Hobabish — and follows them through the years between their crimes and their judgment. It is, in effect, the missing middle of the Watchers saga: what the monsters were doing, and dreaming, while heaven prepared their sentence.
Pieced together from the Qumran fragments and the later Manichaean witnesses, the outline runs like this.
The giants dominate the earth with violence — the fragments echo 1 Enoch's charge that they sinned against birds, beasts, reptiles, and fish, and shed human blood. But their confidence begins to crack when the brothers Ohya and Hahya are visited by nightmares neither can interpret.
Shaken, the giants commission Mahaway to seek out the one being who can interpret dreams: Enoch, who has been taken from among humans and dwells at the ends of the earth. In one of the most vivid surviving scenes, Mahaway rises into the air and flies like a bird across the great desert called Desolation until Enoch hails him. Enoch's answer, sent back in the form of a written tablet, is a rebuke addressed to Shemihazah and his companions: the corruption of the earth has been reported in heaven, judgment is decreed, and the flood is coming. The fragments hint that prayer and repentance are urged on some — but for the giants themselves the dreams mean what they fear.
The reactions are the human heart of the book. Some giants despair; some brawl; Ohya swings between boasting that no power can defeat him and admitting that his true opponent "dwells in the heavens." In the Manichaean version of the story, Ohya battles the sea monster Leviathan. The ending is lost, but every witness points the same way: the flood rises, the Watchers are bound, and the giants do not survive their sentence.
Here is the detail that stops scholars in their tracks: two of the Qumran fragments (4Q530 and 4Q531) list Gilgamesh — the hero-king of the great Babylonian epic — among the giants. Another giant's name, Hobabish, appears to derive from Humbaba, the forest monster Gilgamesh slays in that epic.
This is not a coincidence of spelling. The Jewish author knew Mesopotamian legend and made a pointed move with it: the towering heroes of Babylon are recast as members of the doomed brood of the fallen angels — impressive, violent, and headed for judgment like the rest. It is the only known appearance of Gilgamesh's name in ancient Jewish literature, and apart from a garbled mention by the Roman writer Aelian centuries later, the only appearance of the name outside the cuneiform tradition itself. When the fragments were deciphered, a character lost to the West for two thousand years turned out to have been hiding in a Jewish text about the Nephilim.

They carry unglamorous catalog numbers — 1Q23, 2Q26, 4Q203, 4Q530, 4Q531, 6Q8, and others — and for years nobody knew quite what they were. Aramaic scraps about angels and giants could have belonged to any number of lost works.
The breakthrough came in 1971, when J. T. Milik recognized that the Qumran fragments matched a book already known from the other end of Asia: the Manichaean Book of Giants, whose remains had been recovered from the Turfan oasis in western China and published by W. B. Henning in 1943. Names, scenes, and plot lined up. Two piles of fragments, separated by four thousand miles and a thousand years, turned out to be the same lost book.
The Qumran copies are old — the earliest were penned around 100 BC, and the work itself was likely composed in the third or second century BC, in the same broad era as the other early Enochic writings. Whatever its exact date, it is a genuine document of Second Temple Judaism, not a later legend.
The Book of Giants has one distinction no other Enochic text can claim: it was formally canonized — just not by any church you have heard of. In the third century AD, the Persian prophet Mani founded Manichaeism, a missionary religion that at its height stretched from Roman North Africa to Tang-dynasty China. Mani knew the Book of Giants, rewrote it to fit his own elaborate cosmology, and placed his version among the canonical scriptures of his church.
Manichaean missionaries then did what missionaries do: they translated. Fragments of Mani's Book of Giants survive in Middle Persian, Parthian, Sogdian, and Old Uyghur, recovered by archaeologists at Turfan in the early twentieth century. In some versions the giants' names were localized for new audiences — Ohya and Hahya appear under the names of the Iranian heroes Sam and Nariman. When Manichaeism was eventually persecuted out of existence, its scriptures went with it, and the Book of Giants died its second death — until Qumran.
Honesty matters here, because it is our edge over the hype sites: there is no complete Book of Giants, and no edition can honestly claim otherwise. What survives is a few hundred lines of broken Aramaic from Qumran and a scatter of Manichaean excerpts in four languages. Even the order of the episodes is debated — scholars disagree, for example, about whether Mahaway makes one journey to Enoch or two.
Modern editions therefore reconstruct. Editors triangulate between three witnesses: the Qumran Aramaic fragments, the Manichaean versions, and a much later medieval Jewish retelling, the Midrash of Shemhazai and Azael, which preserves the two brothers and their dreams in Hebrew. The landmark scholarly editions — Milik (1976), John Reeves (1992), and Loren Stuckenbruck (1997) — differ in arrangement precisely because the evidence allows more than one solution. A good modern-English edition tells the story continuously while being candid about where the gaps and editorial judgments lie. That is the standard our own edition holds itself to.
The history-shaped answer: it never had a champion inside the communities that fixed the biblical canons. The rabbis who consolidated the Hebrew Bible after 70 AD received none of the Enochic books, the Book of Giants included. Among Christians, 1 Enoch at least had the letter of Jude quoting it, which kept its case alive for centuries; the Book of Giants had no New Testament citation, no defender like Tertullian, and by the fourth century no apparent circulation in the churches that drew up canon lists. Even the Ethiopian Orthodox Church — the one tradition that canonized 1 Enoch — did not include the Book of Giants.
A curious footnote shows the story was not entirely forgotten in the West: the sixth-century Latin list of accepted and rejected books known as the Gelasian Decree condemns a "book about the giant named Ogias" who fought a dragon after the flood — very plausibly a distant Latin descendant of Ohya and his monster-battling legend, explicitly ruled out of bounds. The Book of Giants was never suppressed in any dramatic sense; like most of the lost books of the Bible, it simply fell outside every canon, stopped being copied, and waited in the ground.
If the Watchers story in 1 Enoch gripped you, the Book of Giants is the natural next step — the same saga told from inside the catastrophe. It is short: even a generous reconstruction reads in well under an hour. And it offers things nothing else in ancient literature quite does:
Read Genesis 6:1–4 first, then the Book of the Watchers, then Giants — the dreams and the flight of Mahaway land far harder when you know the frame. And read it for what it is: not lost scripture, but a vivid, fragmentary, historically fascinating piece of the Enochic tradition that very nearly vanished twice.
