The fool is told to appear in novels where kings take an important part so it's up to us realize where we want him to appear.
Development: In King Lear since the very beginning Shakespeare sets us up in a scene of introduction of his characters. We after reading know that this is a medieval legend and the appearance of the fool is everywhere in the story so it isn't hard to "quote"Ã¯Â¿Â½ his appearances, but physically he appears in ACT I Scene iv when he offers to help the king when things are terrible, a symbol of it is his coxbomb, which is a cap in the form of cock's crest, the symbol of a professional fool then he addresses to Kent and asks to wear his coxbomb because of having been to Lear's side in his disgrace in Scene v the fool asks the king to relax and to sleep for a while because he is very tired, Lear refuses finally he sleeps with the fool to his side.
In ACT II Scene iv the fool addresses to Kent in a metaphorical way to let him know that a messenger he should use his legs a not lost sense, because Lear's legs are tired, so the message is for him to continue with the will of the king but on his way (Kent's).
With magical words made out of wisdom, when Lear is left down Lear still stands by.
The Fool, Kent and others who finally realize about the truth, which was misunderstood because of the love and loyalty that Goneril, Reagan and Edmund were supposed to have to Lear and Gloucester.
