What are a few of the metaphors or similes linked to death in Romeo and Juliet during Act 1?

Death pervades Shakespeare's play Romeo and Juliet. From the outset, in the Prologue, the Chorus announces that the two young lovers will die. Not only do they die, but there are also four other characters who meet their demise during the course of the story. So it's not surprising that death imagery abounds.

In Act I, Scene 1, the Prince suggests that the violent feud has become lethal when he says,

What ho! You...

Death pervades Shakespeare's play Romeo and Juliet. From the outset, in the Prologue, the Chorus announces that the two young lovers will die. Not only do they die, but there are also four other characters who meet their demise during the course of the story. So it's not surprising that death imagery abounds.

In Act I, Scene 1, the Prince suggests that the violent feud has become lethal when he says,

What ho! You men, you beasts,
That quench the fire of your pernicious rage
With purple fountains issuing from your veins

Purple fountains, of course, are a metaphor for the blood that has been shed by the ongoing dispute between the Montagues and Capulets.

Romeo talks about how he is like a dead man because he is in love with a woman who does not share his affection. In his rant to Benvolio about Rosaline, he says,

She hath forsworn to love, and in that vow
Do I live dead, that live to tell it now.

When Paris is asking Capulet for Juliet's hand in marriage the Lord is cautious because Juliet is very young and his only child. His other children have died and he uses personification to tell the reader how precious Juliet is to him:

Earth hath swallowed all my hopes but she;
She’s the hopeful lady of my earth.

After Mercutio's Queen Mab speech in Act I, Scene 4, Romeo has a premonition that he is embarking on a journey that will end in his death. His aside at the end of the scene foreshadows future events, and is metaphorical in its comparison of a "consequence...hanging in the stars" and his ultimate death:

I fear too early, for my mind misgives
Some consequence yet hanging in the stars
Shall bitterly begin his fearful date
With this night’s revels, and expire the term
Of a despisèd life closed in my breast
By some vile forfeit of untimely death.
But he that hath the steerage of my course
Direct my sail. On, lusty gentlemen.

Juliet also uses death imagery when, after meeting and falling in love with Romeo, she asks the Nurse to find out who he is. She uses a simile to say that if he might be married she would rather die:

Go ask his name. [The Nurse goes.] If he be marrièd,
My grave is like to be my wedding bed.
