Is this a dialogue or a monologue from the play, Macbeth?

[To the witches] I'th' name of truth Are ye fantastical, or that indeed Which outwardly ye show? My noble partner You greet with present grace and great prediction Of noble having and of royal hope, That he seems rapt withal. To me you speak not. If you can look into the seeds of time And say which grain will grow and which will not, Speak then to me, who neither beg nor fear Your favors nor your hate.
