In The Odyssey, Antinous is the leading and most arrogant of the suitors trying to marry Penelope while Odysseus is away. He lives in Odysseus’s palace, consumes his wealth, insults his family, and encourages the other suitors toward violence and lawlessness.
Antinous especially hates Telemachus once the young prince begins acting more confidently. He helps organize the plot to ambush and murder Telemachus on his journey home. When Penelope confronts him, she reminds him that Odysseus once saved Antinous’s father, making Antinous’s betrayal even more dishonorable. Antinous still refuses to change his behavior.
He also becomes the clearest example of the suitors’ abuse of hospitality which the poem portrays as a severe moral transgression. When Odysseus returns disguised as a beggar, Antinous mocks him and even throws a stool at him. Odysseus warns that the gods punish such cruelty, and the other suitors themselves admit Antinous has gone too far.
Because he represents the suitors’ arrogance most completely, Antinous is the first man Odysseus kills in the final revenge scene. Odysseus shoots him through the throat just as he lifts a cup of wine to drink. His death signals the collapse of the suitors’ power and the restoration of justice in Ithaca.
Antinous’s character is significant because he is the one who turns the suitors’ behavior from mere opportunism into outright sacrilege. His contempt for hospitality, loyalty, and divine justice makes him a prime example of the reckless pride that repeatedly brings punishment throughout the poem.
