Vindice carries the skull of his murdered beloved, Gloriana, who was killed by the Duke for refusing his sexual advances almost ten years before the action of the play. Vindice addresses the skull in the opening scene, an early appearance that suggests the strong presence of death throughout the play; it also gives the audience a sense of Vindice’s obsession with revenge, given that he’s held on to the skull for the best part of a decade. Later, Vindice employs the skull as the murder weapon when he tricks the Duke into kissing its poison-laden mouth. The use of the skull as the murder weapon accomplishes two significant things: first, it gruesomely allows Gloriana herself to have her revenge on the Duke (as much is possible); second, the skull’s role as a “memento mori”—an object reminder of death—means that the Duke is killed by a symbol of death itself. With these two points in mind, then, the skull allows Vindice not just to kill the Duke, but to make sure he achieves the perfect revenge—the Duke is killed by the exact physical object that best represents his own earlier crime.
Gloriana’s Skull Quotes in The Revenger’s Tragedy
[To the skull] Thou sallow picture of my poisoned love,
My study’s ornament, thou shell of death,
Once the bright face my betrothed lady,
When life and beauty naturally filled out these
These ragged imperfections,
When two heaven-pointed diamonds were set
In those unsightly rings […]
Thee when thou wert appareled in thy flesh
The old duke poisoned,
Because thy purer part would not consent
Unto his palsy-lust
VINDICE: Look you brother,
I have not fashioned this only for show
And useless property, no — it shall bear a part
E'en in it own revenge. This very skull,
Whose mistress the duke poisoned with this drug,
The mortal curse of the earth, shall be revenged
In the like strain and kiss his lips to death.
