Also, in the prologue it states that the dreadful course of their love was destined for death: "The fearful passage of their death marked love". These references of the two lovers inform the audience of the structure of the play itself, which is the fate from which Romeo and Juliet cannot deny, and the "stars" which are controlling their destinies to be together and eventually die tragically.
Fate is signaled through various premonitions that give a clear foresight of the deaths of Romeo and Juliet. In Act II, Friar Lawrence says, "These violent delights have violent end, and in triumph die". This is a clear allusion that is representing that the lovers relationship will end tragically with death. A little later on in the play, Juliet says, "Methinks I see thee, now thou art so low, as one dead in the bottom of a tomb". This prefigures that Juliet will find Romeo dead in a tomb. These two premonitions give a clear description towards the fate of Romeo and Juliet, and what is to come for them in the future. .
The power of fate is overtly shown through various events incorporated into Shakespeare's tragic play. During the course of the play, there is a series of events that take place which are caused by circumstances outside of anyone's control, and which are purely powered by fate and the "stars" which predetermine Romeo and Juliet's future. Shakespeare emphasizes the point that if any of these incidences were absent from the play, than the heartbreaking ending that Romeo and Juliet experienced would not have occurred.
One of these events includes the masquerade ball of the Capulets, where Romeo and Juliet first encounter each other. Romeo and Juliet could not have avoided coming in contact with each other, they were brought together by uncontrollable circumstances. During the course of Act I, Scene II, Old Capulet sends the servant, who is illiterate, to invite people to his party.
