There isn't anything ironic about that..
Odysseus calls to the god Poseidon for vengeance when he escapes from the cave of the Cyclops Polyphemus in Homer's "The Odyssey." This act angers Poseidon, who is the father of Polyphemus, and sets off a series of obstacles for Odysseus on his journey back home.
Odysseus calls himself "Nobody" to trick the Cyclops Polyphemus in the Odyssey. This clever trick allows Odysseus to escape when he blinds Polyphemus and the other Cyclopes ask who harmed him. Polyphemus replies that "Nobody" has harmed him, so they do not come to his aid.
In the end of the Odyssey, the cyclops Polyphemus is blinded by Odysseus and his men before they escape from his cave. As a result of this act, Polyphemus calls upon his father Poseidon to seek revenge on Odysseus, leading to further challenges in Odysseus' journey back home.
Polyphemus calls upon his father Poseidon to curse Odysseus.
Odysseus tells Polyphemus that his name is "Nobody" when asked for his name. This allows Odysseus to trick Polyphemus when he later blinds him and Polyphemus calls for help, claiming that "Nobody" is attacking him.
In Homer's "Odyssey," the soothsayer Teiresias predicts that the Cyclops Polyphemus would be blinded by Odysseus. This prophecy comes true when Odysseus and his men blind Polyphemus in order to escape from his cave. As a result, Polyphemus calls upon his father, Poseidon, to seek revenge on Odysseus, which leads to further challenges for Odysseus on his journey home.
When his fellow cyclops came into the cave, Polyphemus said that "Nobody" was trying to kill him (Nobody = a name). The others heard it as "nobody" was trying to kill him, meaning that he was not in danger (nobody = no one).
Well, according to google dictionary, a ninny is a foolish person. In the Cyclopes, the Giant calls Odysseus a ninny because Polyphemus (the Cyclops) is mad about being stabbed in the eye and going blind, so as an insult, he calls Odysseus a ninny. Hope this helps!
Polyphemus says to his fellow Cyclops that he has been blinded by "Nobody" when he is attacked by Odysseus in Homer's "The Odyssey." He then calls for help from the other Cyclops, but when they hear him say that "Nobody" has hurt him, they assume he is fine and do not come to his aid.
The next morning in "The Odyssey," after being blinded by Odysseus, the giant Polyphemus awakens and discovers that his sheep have been driven away. In his rage and confusion, he calls upon his father, Poseidon, to curse Odysseus, which leads to further obstacles for Odysseus and his crew during their journey home. Polyphemus's cries also alert other Cyclopes, who come to his aid but are misled by him about the identity of his attacker.
At the end of the Cyclops adventure in Homer's "Odyssey," Polyphemus, after being blinded by Odysseus, calls upon his father, Poseidon, to curse Odysseus. He prays for revenge, which leads Poseidon to make Odysseus's journey home perilous and prolonged. This curse results in numerous trials and tribulations for Odysseus and his crew as they attempt to return to Ithaca.
In Homer's "Odyssey," specifically in the episode involving the Cyclops Polyphemus, Odysseus does not lose any men directly to the Cyclops during their encounter. Instead, he cleverly devises a plan to escape from Polyphemus after blinding him. However, later in the story, Polyphemus calls upon his father Poseidon to avenge him, which leads to further hardships for Odysseus and his crew, resulting in losses later on, but not specifically in the encounter with the Cyclops.
