Tartarus (Ancient Greek: Τάρταρος, Tártaros) is a primordial entity and a deep cosmic region in ancient Greek mythology.
In early Greek cosmology, particularly the Theogony of Hesiod, Tartarus is one of the earliest entities to come into existence, alongside Chaos, Gaia (Earth) and Eros. It is simultaneously described as a vast, dark abyss beneath the Earth and, in some traditions, as a primordial divine being.
Tartarus should not be regarded simply as another name for Hades. In the earliest surviving Greek literature, Hades is the realm of the dead, whereas Tartarus is a much deeper cosmic region associated particularly with imprisonment, divine punishment and the confinement of enemies of the Olympian gods.
Homer describes Tartarus as lying as far beneath Hades as the heavens are above the Earth.
Over time, the concept developed. Later Greek writers increasingly associated Tartarus with punishment after death, while Roman authors, particularly Virgil, developed a more elaborate vision of Tartarus as a prison for the wicked within the underworld.
The concept subsequently became an important source for later ideas of an infernal realm.
Name and meaning
The Greek name is Τάρταρος (Tartaros), with the plural or alternative form Τάρταρα (Tartara) also occurring in ancient literature.
The precise etymology of the word is uncertain. The Liddell–Scott–Jones Greek-English Lexicon records its use in Homer and Hesiod for the deep cosmic region and notes that later usage could extend to the netherworld more generally.
There is no secure consensus that the name derives from another known Greek word. Proposed connections and later attempts to explain its origin remain uncertain.
Tartarus in Hesiod
The earliest major surviving account of Tartarus occurs in Hesiod's Theogony, generally dated to the Archaic period.
Hesiod presents Tartarus as one of the fundamental entities of the cosmos:
“Chaos came to be, but next ... Earth ... and dim Tartarus in the depth of the wide-pathed Earth, and Eros.”
This places Tartarus among the primordial elements of creation rather than introducing it merely as a destination for sinful human souls.
The Theogony subsequently gives Tartarus a remarkable cosmological scale. It is situated as far below the Earth as Heaven is above it. Hesiod illustrates the distance through the image of a bronze anvil: an anvil falling from Heaven would take nine nights and days to reach Earth and would reach it on the tenth; falling from Earth, it would take another nine nights and days to reach Tartarus.
Tartarus is surrounded by barriers, including bronze walls and gates, and is described as a place of darkness and confinement.
Hesiod's description is not a simple geographical map, however, and ancient Greek descriptions of the underworld are not always internally consistent.
The prison of the Titans
Tartarus is most famously associated with the Titans.
During the Titanomachy, the war between Zeus and his allies and the older generation of gods, the Titans were defeated. Zeus and his allies subsequently imprisoned the defeated Titans in Tartarus. Hesiod describes them as being bound beneath the Earth and guarded by the Hecatoncheires—the hundred-handed beings Cottus, Briareus and Gyges.
The imprisonment of the Titans established one of Tartarus's central mythological functions: it was not merely a place beneath the world, but a cosmic prison capable of containing beings powerful enough to threaten the established order of the gods.
Homer also refers to Tartarus as the place where the Titans were confined. In the Iliad, Cronus and Iapetus are described as existing in the deepest limits of the cosmos, surrounded by Tartarus.
Tartarus and Hades
The distinction between Tartarus and Hades is important.
Hades can refer both to the god who rules the dead and to his realm, where the deceased generally reside. Tartarus, by contrast, was originally a deeper cosmic region distinct from the ordinary realm of the dead.
Homer's Iliad places Tartarus below Hades, describing it as being as far beneath Hades as Heaven is above Earth. This makes Tartarus a kind of cosmic inverse of the heavenly realm.
The distinction became less rigid in later literature. The Greek lexicographical tradition records later uses in which Tartarus could refer more generally to the netherworld.
Consequently, descriptions of Tartarus in later Greek and Roman literature cannot always be projected backwards onto the mythology of Homer and Hesiod.
Tartarus and Typhon
Tartarus also plays a role in the mythology of Typhon (or Typhoeus), one of the most formidable monsters in Greek mythology.
In Hesiod's account, Gaia gives birth to Typhoeus through Tartarus after the defeat of the Titans. Typhoeus is described as a gigantic monster possessing numerous serpent-like heads and immense power. He challenges Zeus but is ultimately defeated by the Olympian god. Zeus then casts Typhoeus into Tartarus.
The myth consequently makes Tartarus both the source of a primordial threat to Zeus and the prison into which that threat is eventually confined.
The connection between Typhon and Tartarus was subsequently developed in other traditions. Ancient writers sometimes associated Typhon with volcanic forces, and later interpretations connected his imprisonment with volcanic regions such as Mount Etna.
Other inhabitants
Tartarus was not exclusively occupied by the Titans. Hesiod associates the region with several primordial and cosmic beings.
The Titans are its most important prisoners, while other figures are described as living in or being associated with its depths. The Cyclopes and Hecatoncheires, for example, are imprisoned there at different stages of the mythological succession before the Hecatoncheires become allies and guardians of Zeus.
The mythology therefore presents Tartarus less as a conventional prison containing a fixed population and more as a cosmic region capable of containing dangerous or primordial beings.
Tartarus as a place of punishment
The association of Tartarus with punishment became increasingly prominent in later Greek thought. A significant development appears in the philosophy of Plato.
In the Gorgias, Plato presents a post-mortem system in which souls are judged according to their lives. Those requiring punishment are sent to appropriate places of correction, including Tartarus. This represents a development beyond the earlier Homeric conception of Tartarus primarily as a cosmic prison for divine enemies.
This later conception helped establish the familiar idea of Tartarus as a place where particularly wicked beings or souls undergo punishment.
It is therefore misleading to assume that the earliest Greek conception of Tartarus was simply equivalent to the later idea of Hell. The concept changed over centuries.
Tartarus in Roman mythology
Roman writers inherited and transformed the Greek concept. The most influential Roman description occurs in Virgil's Aeneid.
During Aeneas's journey through the underworld, the Sibyl describes Tartarus as an exceptionally formidable region associated with punishment. Virgil places it beyond the ordinary regions of the dead and gives it elaborate architectural and geographical features.
The Roman conception includes massive walls, gates and guardians, together with the river Phlegethon. The Fury Tisiphone is associated with guarding the entrance.
Virgil's Tartarus contains figures who have committed serious offences against gods, family or society. Their punishments reflect the offences they committed, producing a form of moralised afterlife that differs substantially from the earlier Homeric and Hesiodic descriptions.
This Roman development became one of the most influential ancient representations of Tartarus.
Tartarus and Elysium
In later descriptions of the afterlife, Tartarus became increasingly associated with its apparent opposite, Elysium.
Elysium was a place of exceptional happiness associated with heroes and, in later traditions, virtuous souls. Tartarus represented confinement and punishment. The contrast produced a more clearly divided moral geography of the afterlife than is found in the earliest Homeric descriptions.
This should not be interpreted as a single, universally accepted Greek model of the afterlife. Greek beliefs varied considerably between periods, authors and religious traditions.
Cosmological significance
Tartarus has an unusual position in Greek cosmology because it functions simultaneously as:
- a primordial entity
- a cosmic region
- an abyss beneath the Earth
- a prison for defeated divine beings
- the source or parent of certain monstrous forces
- and, in later traditions, a place of punishment
The earliest mythology therefore does not present Tartarus simply as a Greek equivalent of Hell.
Hesiod's cosmology instead places Tartarus within a system of primordial forces that includes Chaos, Gaia, Eros, Nyx (Night), Erebus and Uranus (Heaven). Tartarus is particularly significant because it represents the extreme opposite of the celestial realm.
The imagery of an abyss beneath the foundations of the Earth also made Tartarus one of the most striking concepts in ancient Greek cosmology.
Tartarus in later tradition
The meaning of Tartarus continued to evolve after classical antiquity. Roman literature increasingly treated it as an infernal prison, while Christian writers were familiar with the Greek term and its association with imprisonment and punishment.
The Greek word also appears in the New Testament, where Tartarus is used in a verbal form in 2 Peter 2:4 to describe rebellious angels being consigned to a place of darkness. This represents a later reception of the Greek concept rather than evidence that Tartarus was originally a Christian conception.
The word subsequently entered European languages and became associated with the idea of the deepest or most terrible region of the underworld.
Was Tartarus Really the Greek Hell?
The modern image of Tartarus as a subterranean realm of fire and eternal punishment is only partly ancient.
In the earliest surviving Greek mythology, Tartarus is something stranger: a primordial cosmic region that existed from the beginning of creation, far beneath Earth, where defeated divine powers could be imprisoned.
Its transformation into a place of moral punishment happened gradually, as Greek philosophers and later Roman writers reshaped the older mythology.
Interpretation
The changing descriptions of Tartarus demonstrate that Greek mythology did not possess a single fixed geography of the afterlife.
In Homer, Tartarus is primarily a remote cosmic prison. Hesiod expands it into a fundamental component of the structure of the universe. Plato incorporates it into a philosophical theory of post-mortem judgment, while Virgil transforms it into an elaborate infernal prison populated by punished sinners.
Consequently, descriptions of Tartarus as simply “the Greek Hell” are broadly understandable when referring to later traditions, but they obscure the much older and more complex role of Tartarus in Greek cosmology.
FAQ
1. Tartarus may be older than the Olympian gods
In Hesiod's Theogony, Tartarus isn't created by Zeus or even by the Titans. It appears right near the beginning of creation, alongside Chaos, Gaia and Eros.
That makes Tartarus fundamentally different from the popular image of it as a prison invented by the Olympians. It is presented as part of the original structure of the cosmos.
2. It was unimaginably far below Earth
Hesiod gives Tartarus an extraordinary measurement. He says that an anvil falling from Heaven would take nine days and nights to reach Earth, and another nine days and nights to reach Tartarus.
That isn't simply poetic scenery. It establishes Tartarus as an almost unimaginably remote region — effectively the cosmic basement of the universe.
3. Tartarus had its own terrifying architecture
Hesiod describes Tartarus as surrounded by bronze boundaries, with gates and enormous barriers.
The imagery becomes surprisingly physical: Tartarus isn't merely an abstract state of punishment. It is portrayed as a place with boundaries, entrances and immense depth.
4. The Titans weren't originally “dead”
This is an important distinction. The defeated Titans weren't destroyed when Zeus won the Titanomachy. Many were imprisoned in Tartarus. The Hecatoncheires — the Hundred-Handed Ones — were appointed as their guards.
So Tartarus is partly a cosmic maximum-security prison for defeated gods.
5. Tartarus was connected to the birth of one of mythology's greatest monsters
Hesiod says Gaia and Tartarus produced Typhon. That's extraordinary because Tartarus is therefore not merely a prison: it becomes one of the parental forces behind the greatest threat to Zeus's rule.
Typhon subsequently attacks Zeus and is defeated and confined.
There is almost a mythological cycle here:
Tartarus → produces a cosmic threat → Zeus defeats it → Tartarus becomes its prison.
6. It wasn't originally a place where ordinary bad people went
This is probably the biggest misconception worth highlighting. The earliest surviving Greek sources don't present Tartarus as a general destination for sinners. Its principal occupants are primordial beings and divine enemies, particularly the Titans.
The idea of Tartarus as a place where wicked human souls are punished becomes much more prominent in later Greek philosophical and literary traditions, especially Plato and subsequently Roman literature.
7. Plato turned it into something much closer to Hell
In Plato's Gorgias, Tartarus becomes part of a system of post-mortem judgement and punishment.
That is a major conceptual development. The earlier cosmic prison becomes increasingly associated with moral justice. This helps explain why modern descriptions of Tartarus often sound much more like Hell than Hesiod's original account does.
8. Virgil made it even more horrific
Virgil's Aeneid gives us one of the most influential later descriptions. His Tartarus has enormous walls, gates, guards and punishments for various categories of offenders. It is essentially an elaborate infernal prison within the Roman underworld.
This is probably where much of the familiar Western visual image of Tartarus comes from.
9. Tartarus appears in the New Testament
There's an interesting linguistic footnote here. In 2 Peter 2:4, the Greek text uses the verb tartarōsas — essentially meaning “having cast into Tartarus” — in reference to rebellious angels.
That is unusual because Tartarus isn't simply being used as a synonym for the ordinary realm of the dead. It demonstrates that the ancient Greek concept had survived into the linguistic world of early Christianity.
10. Tartarus wasn't originally a lake of fire
The familiar imagery of fire, flames and eternal torture is strongly associated with later interpretations of the underworld. But Hesiod's Tartarus is primarily characterised by darkness, distance, confinement and cosmic depth.
So the popular image of Tartarus as a fiery Hell is actually a later development, not the starting point.
11. It may have been conceived almost as the opposite of Heaven
There's a beautiful symmetry in the ancient cosmology. Uranus/Heaven is above. Gaia/Earth is between. Tartarus is far below.
Hesiod's description effectively creates a gigantic vertical universe:
Heaven
↓
Earth
↓
Hades
↓
Tartarus
That makes Tartarus more than an underworld location. It represents the deepest extreme of the cosmos.
12. The name's origin is genuinely uncertain
Despite thousands of years of interpretation, the etymology of Tartarus isn't securely established.
That itself is interesting because it means we can confidently describe how ancient Greeks used the word, while being much less certain about where the word itself came from.
