40 free Cyclops trivia questions with answers — history quiz, new questions added Oct 2026.
The Cyclops is one of the most recognisable monsters ever imagined: a giant with a single eye in the middle of its forehead. Yet the Greeks told stories about more than one kind. Some were savage herdsmen living in caves, some were master craftsmen who armed the gods, and some were credited with building walls that no human could have raised. This quiz turns the best Cyclops fun facts into questions. It covers the famous encounter with Odysseus in Homer, the older family of giants in Hesiod, the lovesick monster of later poets, and the theories about where the legend came from. It also follows the name into paintings, comics, cartoons, film, natural history and a real naval mystery. It suits mythology fans, students, teachers and quiz hosts. The questions run from classroom favourites to a few that will test a keen reader of the classics, and every answer comes with a short explanation.

Q 01A large central nasal opening in the skull of which animal may have inspired Cyclops legends?
Elephant
Elephant skulls have a wide central hole for the trunk that can pass for a single giant eye socket. Palaeontologist Othenio Abel suggested the link in 1914, though later scholars doubt it.
Q 02Which false name did Odysseus give Polyphemus so the Cyclops's cries for help made no sense?
Nobody
Nobody, or Outis in Greek, was the trick: when the blinded giant cried that Nobody was hurting him, his neighbours shrugged and went home.
Q 03The Navy coal carrier USS Cyclops, which vanished without trace in 1918, is often linked to which region?
Bermuda Triangle
Bermuda Triangle lore claims the vessel, though a heavy ore cargo, engine trouble and bad weather are likelier culprits. Two of its sister colliers later vanished at sea as well.
Q 04To the ancient Greeks, the name Cyclops, from the words kyklos and ops, meant which of these?
Round eye
Round eye is the literal sense: kyklos means circle and ops means eye. Hesiod says the giants got the name from the single circular eye set in the middle of their foreheads.
Q 05Odysseus escaped the cave of the blinded Cyclops Polyphemus by clinging to which part of a ram?
Its belly
Its belly was the one place the blind giant never checked: he stroked each animal's back as it left the cave. Odysseus hid in the fleece under the biggest ram, his men under others tied in threes.
Q 06Which weapon did Hesiod's three Cyclopes forge for Zeus after he freed them from prison?
Thunderbolt
Thunderbolt in hand, Zeus went on to defeat the Titans and take the throne of the gods. The brothers' names fit the gift: Brontes, Steropes and Arges mean Thunder, Lightning and Bright.
Q 07Which god did the blinded Cyclops Polyphemus call on as his father to curse Odysseus's voyage home?
Poseidon
Poseidon heard the prayer: Odysseus took ten years to reach Ithaca and arrived alone, on a stranger's vessel, with every one of his men lost.
Q 08What rash mistake did Odysseus make as he sailed away from the blinded Cyclops Polyphemus?
He shouted his real name
He shouted his real name across the water, boasting that Odysseus of Ithaca had done the deed. That let the giant name him in a curse, and the gods made sure it came true.
Q 09Which Arabian Nights hero blinds a man-eating, Cyclops-like giant with red-hot iron spits?
Sinbad
Sinbad meets the monster on his third voyage, after it has roasted several of his shipmates. The translator Richard Burton noted that the giant was plainly modelled on Polyphemus.
Q 10In Rick Riordan's Percy Jackson books, which young Cyclops turns out to be Percy's half-brother?
Tyson
Tyson first appears in The Sea of Monsters as a homeless schoolmate whom Percy befriends. The same book sends the heroes to rescue their friend Grover from Polyphemus himself.
Q 11Legend says the Cyclopes built the walls of which Greek citadel, entered through the Lion Gate?
Mycenae
Mycenae's walls use boulders so heavy that later Greeks could not believe ordinary men had moved them. The style is still called Cyclopean masonry, and nearby Tiryns earned the same legend.
Q 12Ancient poets set the Cyclopes' forge beneath which volcano, whose smoke the myth helped explain?
Mount Etna
Mount Etna's fire and rumbling were put down to the giants hammering away underground. Other writers moved the workshop to the small volcanic islands just to the north.
Q 13Which god is said to have killed the Cyclopes after their handiwork felled his son Asclepius?
Apollo
Q 21What stopped Odysseus from killing the Cyclops Polyphemus with his sword while the giant slept?
The cave's door stone
The cave's door stone was so heavy that twenty-two wagons could not have shifted it, and only the giant could roll it aside. Kill him and the Greeks would have been sealed in for good.
Q 22Odysseus blinded the Cyclops Polyphemus with a stake cut from the giant's own club of which wood?
Olive
Olive wood, still green, formed a club as big as a ship's mast. Odysseus cut off about six feet, sharpened it, hardened the point in the fire and hid it under the dung on the cave floor.
Q 23Odysseus and his men found the cave of the Cyclops Polyphemus stocked with racks of which food?
Cheese
Apollo could not strike at Zeus, who had killed the healer for raising the dead, so he took revenge on the craftsmen instead. His punishment was a spell as herdsman to the mortal king Admetus.
Q 14Which god hated his sons, Hesiod's three Cyclopes, and locked them underground at birth?
Uranus
Uranus loathed all his monstrous children and thrust each one back into the earth as it was born. His son Cronus toppled him but left the one-eyed brothers locked away.
Q 15Which primordial goddess, mother of the Titans, also gave birth to the first three Cyclopes?
Gaia
Gaia bore them after the Titans and, furious at seeing her children shut away, armed her youngest Titan son with a sickle to overthrow their father.
Q 16The Cyclopes were cast into which pit, said to lie as far below the earth as the sky is above?
Tartarus
Tartarus was the deepest part of the Greek underworld and later the jail of the defeated Titans too. Zeus released the one-eyed smiths from it to gain allies in his war for the throne.
Q 17From Callimachus onward, poets cast the Cyclopes as assistants at the forge of which Greek god?
Hephaestus
Hephaestus was born too late to arm Zeus for the war with the Titans, so the first myths gave that job to the one-eyed brothers. Later poets simply merged the two sets of divine metalworkers.
Q 18In Apollodorus, which gift from the Cyclopes made Hades invisible in the war on the Titans?
A helmet
A helmet, known as the cap of invisibility, was their present to the lord of the dead. It was later lent out: the hero Perseus wore it to slip away after beheading Medusa.
Q 19Which fifty-headed giants were the brothers of the Cyclopes and shared their underground prison?
Hecatoncheires
Hecatoncheires means Hundred-Handed Ones: Cottus, Briareus and Gyges each had a hundred arms to go with the fifty heads. Once freed, they pelted the Titans with enormous boulders.
Q 20Which drink, a gift from the priest Maron, did Odysseus use to send the Cyclops Polyphemus to sleep?
Wine
Wine this strong was normally mixed with twenty parts of water, and Odysseus served it neat. Three bowls later the giant collapsed, giving the Greeks their chance.
Cheese filled the racks because the giant was a careful dairy farmer who milked his ewes and goats himself. The crew begged Odysseus to grab some and run; he insisted on staying to meet the owner.
Q 24By eating Odysseus's men, the Cyclops Polyphemus broke xenia, the sacred Greek code of what?
Hospitality
Hospitality to strangers was protected by Zeus himself, and a guest could expect a meal and a parting gift. The giant sneered that his kind cared nothing for Zeus, then ate two of his visitors.
Q 25Which sea nymph does the lovesick Cyclops Polyphemus woo with songs in poems by Theocritus and Ovid?
Galatea
Galatea turns him down for his looks, and Homer's savage becomes an absurd, lovesick shepherd. In Theocritus he finds that singing about her is the only cure for the heartache.
Q 26In Ovid, what did young Acis become after the jealous Cyclops Polyphemus crushed him with a rock?
A river
A river sprang from his blood as it trickled out from under the rock, transformed by the sea nymph who loved him. Handel later set the story as a pastoral opera in English.
Q 27The ancient Athenian drama Cyclops is the only complete surviving example of which stage genre?
Satyr play
Satyr play was the bawdy afterpiece staged after a set of three tragedies, with a chorus of satyrs for comic relief. Here they are the giant's unwilling slaves, herding his flock.
Q 28In Virgil's epic, which Trojan hero rescues a Greek sailor Odysseus left behind among the Cyclopes?
Aeneas
Aeneas takes the castaway Achaemenides aboard and casts off with the blinded Polyphemus in pursuit. The scene lets Virgil tie his Roman epic directly to Homer's.
Q 29The Cyclopean Isles, said to be rocks Polyphemus hurled at Odysseus, lie off which Italian island?
Sicily
Sicily's east coast has the sea stacks just off the village of Aci Trezza. Geologists give them a less dramatic origin: they are columns of basalt about half a million years old.
Q 30Which seer warned the Cyclops Polyphemus that a man named Odysseus would one day take his sight?
Telemus
Telemus had lived among the giants as their resident prophet. Polyphemus admits he ignored the warning because he expected a towering hero, not a puny stranger with a skin of strong drink.
