In his Latin epic Aeneid, Virgil has the hero Aeneas follow in the footsteps of Odysseus, the hero of Homers Odyssey. Approaching Sicily and Mount Etna, in Book 3 of the Aeneid, Aeneas manages to survive the dangerous Charybdis, and at sundown comes to the land of the Cyclopes, while "near at hand Aetna thunders". The Cyclopes are described as being "in shape and size like Polyphemus ... a hundred other monstrous Cyclopes [who] dwell all along these curved shores and roam the high mountains." After narrowly escaping from Polyphemus, Aeneas tells how, responding to the Cyclops "mighty roar":

the race of the Cyclopes, roused from the woods and high mountains, rush to the harbour and throng the shores. We see them, standing impotent with glaring eye, the Aetnean brotherhood, their heads towering to the sky, a grim conclave: even as when on a mountaintop lofty oaks or cone-clad cypresses stand in mass, a high forest of Jove or grove of Diana. Later, in Book 8 of the same poem, Virgil has the Hesiodic Cyclopes Brontes and Steropes, along with a third Cyclopes which he names Pyracmon, work in an extensive network of caverns stretching from Mount Etna to the Aeolian Islands. As the assistants of the smith-god Vulcan, they forge various items for the gods: thunderbolts for Jupiter, a chariot for Mars, and armor for Minerva:

In the vast cave the Cyclopes were forging iron—Brontes and Steropes and bare-limbed Pyracmon.
But Cronus once again bound the six brothers, and reimprisoned them in Tartarus.As in Hesiods account, Rhea saved Zeus from being swallowed by Cronus, and Zeus was eventually able to free his siblings, and together they waged war against the Titans. According to Apollodorus, in the tenth year of that war, Zeus learned from Gaia, that he would be victorious if he had the Hundred-Handers and the Cyclopes as allies. So Zeus slew their warder Campe (a detail not found in Hesiod) and released them, and in addition to giving Zeus his thunderbolt (as in Hesiod), the Cyclopes also gave Poseidon his trident, and Hades a helmet (presumably the same cap of invisibility which Athena borrowed in the Iliad), and "with these weapons the gods overcame the Titans".Apollodorus also mentions a tomb of Geraestus, "the Cyclops" at Athens upon which, in the time of king Aegeus, the Athenians sacrificed the daughters of Hyacinth. Nonnus
Dionysiaca, composed in the 4th or 5th century BC, is the longest surviving poem from antiquity – 20,426 lines. It is written by the poet Nonnus in the Homeric dialect, and its main subject is the life of Dionysus. It describes a war that occurred between Dionysus troops and those of the Indian king Deriades. In book 28 of the Dionysiaca the Cyclopes join with Dionysian troops, and they prove to be great warriors and crush most of the Indian kings troops.
