Apemantus is a professional cynic, a snarling, nasty man who insults everybody he meets without appearing to derive any pleasure from doing so.
He sees through flattery and refuses gifts from Timon, eating only poorly at his table. Though he pretends to like nobody, Apemantus strives to make Timon realize just how foolishly he is acting, but does not give his advice in the most diplomatic manner. When Timon loses all his wealth and becomes a misanthrope in the forest, it becomes evident that Apemantus is something of a poseur, who does not appreciate the fact that someone is stealing his role. Even though he claims to love no-one but himself, Apemantus still tries to feed Timon in the forest, only to be rejected by a man who now hates humanity even more than he does himself. The discovery that it is possible to be even nastier than he is enrages Apemantus, who tells everybody that Timon has found some gold so that he will be beset by visitors.
