Cyclops Junction Design

In Greek mythology and later Roman mythology, the Cyclopes ( ; el, Κύκλωπες, ''Kýklōpes'', "Circle-eyes" or "Round-eyes"; singular Cyclops ; , ''Kýklōps'') are giant one-eyed creatures. Three groups of Cyclopes can be distinguished. In Hesiod's ''Theogony'', the Cyclopes are the three brothers Brontes, Steropes, and Arges, who made for Zeus his weapon the thunderbolt. In Homer's ''Odyssey'', they are an uncivilized group of shepherds, the brethren of Polyphemus encountered by Odysseus. Cyclopes were also famous as the builders of the Cyclopean walls of Mycenae and Tiryns.

In ''Cyclops'', the fifth-century BC play by Euripides, a chorus of satyrs offers comic relief based on the encounter of Odysseus and Polyphemus. The third-century BC poet Callimachus makes the Hesiodic Cyclopes the assistants of smith-god Hephaestus; as does Virgil in the Latin epic ''Aeneid'', where he seems to equate the Hesiodic and Homeric Cyclopes.

From at least the fifth century BC, Cyclopes have been associated with the island of Sicily and the volcanic Aeolian Islands.

Kinds

Three groups of Cyclopes can be distinguished: the Hesiodic, the Homeric and the wall-builders. In Hesiod's ''Theogony'', the Cyclopes are the three brothers: Brontes, Steropes, and Arges, sons of Uranus and Gaia, who made for Zeus his characteristic weapon, the thunderbolt. In Homer's ''Odyssey'', the Cyclopes are an uncivilized group of shepherds, one of whom, Polyphemus, the son of Poseidon, is encountered by Odysseus. Cyclopes were also said to have been the builders of the Cyclopean walls of Mycenae and Tiryns. A scholiast, quoting the fifth-century BC historian Hellanicus, tells us that, in addition to the Hesiodic Cyclopes (whom the scholiast describes as "the gods themselves"), and the Homeric Cyclopes, there was a third group of Cyclopes: the builders of the walls of Mycenae.

Hesiodic Cyclopes

Hesiod, in the ''Theogony'' (c. 700 BC), described three Cyclopes: Brontes, Steropes, and Arges, who were the sons of Uranus (Sky) and Gaia (Earth), and the brothers of the Titans and Hundred-Handers, and who had a single eye set in the middle of their foreheads. They made for Zeus his all-powerful thunderbolt, and in so doing, the Cyclopes played a key role in the Greek succession myth, which told how the Titan Cronus overthrew his father Uranus, and how in turn Zeus overthrew Cronus and his fellow Titans, and how Zeus was eventually established as the final and permanent ruler of the cosmos. The names that Hesiod gives them: Arges (Bright), Brontes (Thunder), and Steropes (Lightning), reflect their fundamental role as thunderbolt makers. As early as the late seventh-century BC, the Cyclopes could be used by the Spartan poet Tyrtaeus to epitomize extraordinary size and strength.

According to the accounts of Hesiod and mythographer Apollodorus, the Cyclopes had been imprisoned by their father Uranus. Zeus later freed the Cyclopes, and they repaid him by giving him the thunderbolt. The Cyclopes provided for Hesiod, and other theogony-writers, a convenient source of heavenly weaponry, since the smith-god Hephaestus—who would eventually take over that role—had not yet been born. According to Apollodorus, the Cyclopes also provided Poseidon with his trident and Hades with his cap of invisibility, and the gods used these weapons to defeat the Titans.

Although the primordial Cyclopes of the ''Theogony'' were presumably immortal (as were their brothers the Titans), the sixth-century BC Hesiodic ''Catalogue of Women'', has them being killed by Apollo. Later sources tell us why: Apollo's son Asclepius had been killed by Zeus' thunderbolt, and Apollo killed the Cyclopes, the makers of the thunderbolt, in revenge. According to a scholiast on Euripides' ''Alcestis'', the fifth-century BC mythographer Pherecydes supplied the same motive, but said that Apollo, rather than killing the Cyclopes, killed their ''sons'' (one of whom he named Aortes) instead. No other source mentions any offspring of the Cyclopes. A Pindar fragment suggests that Zeus himself killed the Cyclopes to prevent them from making thunderbolts for anyone else.

The Cyclopes' prowess as craftsmen is stressed by Hesiod who says "strength and force and contrivances were in their works." Being such skilled craftsmen of great size and strength, later poets, beginning with the third-century BC poet Callimachus, imagine these Cyclopes, the primordial makers of Zeus' thunderbolt, becoming the assistants of the smith-god Hephaestus, at his forge in Sicily, underneath Mount Etna, or perhaps the nearby Aeolian Islands. In his ''Hymn to Artemis'', Callimachus has the Cyclopes on the Aeolian island of Lipari, working "at the anvils of Hephaestus", make the bows and arrows used by Apollo and Artemis. The first-century BC Latin poet Virgil, in his epic ''Aeneid'', has the Cyclopes: "Brontes and Steropes and bare-limbed Pyracmon" toil under the direction of Vulcan (Hephaestus), in caves underneath Mount Etna and the Aeolian islands. Virgil describes the Cyclopes, in Vulcan's smithy forging iron, making a thunderbolt, a chariot for Mars, and Pallas's Aegis, with Vulcan interrupting their work to command the Cyclopes to fashion arms for Aeneas. The later Latin poet Ovid also has the Hesiodic Cyclopes Brontes and Steropes (along with a third Cyclops named Acmonides), work at forges in Sicilian caves.

According to a Hellenistic astral myth, the Cyclopes were the builders of the first altar. The myth was a catasterism, which explained how the constellation the Altar (Ara) came to be in the heavens. According to the myth, the Cyclopes built an altar upon which Zeus and the other gods swore alliance before their war with the Titans. After their victory, "the gods placed the altar in the sky in commemoration", and thus began the practice, according to the myth, of men swearing oaths upon altars "as a guarantee of their good faith".

According to the second-century geographer Pausanias, there was a sanctuary called the "altar of the Cyclopes" on the Isthmus of Corinth at a place sacred to Poseidon, where sacrifices were offered to the Cyclopes. There is no evidence for any other cult associated with the Cyclopes. According to a version of the story in the ''Iliad'' scholia (found nowhere else), when Zeus swallowed Metis, she was pregnant with Athena by the Cyclops Brontes.

Although described by Hesiod as "having very violent hearts" (''ὑπέρβιον ἦτορ ἔχοντας''), and while their extraordinary size and strength would have made them capable of great violence, there is no indication of the Hesiodic Cyclopes having behaved in any other way than as dutiful servants of the gods.

Walter Burkert suggests that groups or societies of lesser gods, like the Hesiodic Cyclopes, "mirror real cult associations (''thiasoi'') ... It may be surmised that smith guilds lie behind Cabeiri, Idaian Dactyloi, Telchines, and Cyclopes."

Homeric Cyclopes

In an episode of Homer's ''Odyssey'' (c. 700 BC), the hero Odysseus encounters the Cyclops Polyphemus, the son of Poseidon, a one-eyed man-eating giant who lives with his fellow Cyclopes in a distant land. The relationship between these Cyclopes and Hesiod's Cyclopes is unclear. Homer described a very different group of Cyclopes, than the skilled and subservient craftsman of Hesiod. Homer's Cyclopes live in the "world of men" rather than among the gods, as they presumably do in the ''Theogony''. The Homeric Cyclopes are presented as uncivilized shepherds, who live in caves, savages with no regard for Zeus. They have no knowledge of agriculture, ships or craft. They live apart and lack any laws.

The fifth-century BC playwright Euripides also told the story of Odysseus' encounter with Polyphemus in his satyr play ''Cyclops''. Euripides' Cyclopes, like Homer's, are uncultured cave-dwelling shepherds. They have no agriculture, no wine, and live on milk, cheese and the meat of sheep. They live solitary lives, and have no government. They are inhospitable to strangers, slaughtering and eating all who come to their land. While Homer does not say if the other Cyclopes are like Polyphemus in their appearance and parentage, Euripides makes it explicit, calling the Cyclopes "Poseidon's one-eyed sons". And while Homer is vague as to their location, Euripides locates the land of the Cyclopes on the island of Sicily near Mount Etna.

Like Euripides, Virgil has the Cyclopes of Polyphemus live on Sicily near Etna. For Virgil apparently, these Homeric Cyclopes are members of the same race of Cyclopes as Hesiod's Brontes and Steropes, who live nearby.

Cyclopean wall-builders

Cyclopes were also said to have been the builders of the so-called 'Cyclopean' walls of Mycenae, Tiryns, and Argos. Although they can be seen as being distinct, the Cyclopean wall-builders share several features with the Hesiodic Cyclopes: both groups are craftsmen of supernatural skill, possessing enormous strength, who lived in primordial times. These builder Cyclopes were apparently used to explain the construction of the stupendous walls at Mycenae and Tiryns, composed of massive stones that seemed too large and heavy to have been moved by ordinary men.

These master builders were famous in antiquity from at least the fifth century BC onwards. The poet Pindar has Heracles driving the cattle of Geryon
