 Studying Romeo and Juliet, here's how you can analyse the prologue. Pay attention to the structure of the prologue, it's written as a sonnet and it's also written in 9-bit pentameter. It sets the scene for what will happen in the play. The caesura in the opening line creates intrigue, we wonder what's so unique about these two households. We'll learn that these households, these families are alike in dignity, however they break to new mutiny. Now this rhyming couplet highlights that this is a story about a family that's been at war. The alliteration here in front, forth, fatal and foes creates a strong sense of foreboding. It foreshadows the tragic end and the tragic deaths of Romeo and Juliet. Shakespeare uses this celestial language to show that the love between Romeo and Juliet was going to be doomed. These words belonging to the semantic field of angered show just how destructive this family feud was. Remember contextually, family feuds and blood feuds were quite common, so this could be Shakespeare's way of criticising these feuds.
