Duncan’s purple cloak

Duncan’s purple cloak is both ceremonial regalia and the focus of an explicit promise of protection. Its removal during the attack on Duncan strips away that promise’s visible emblem just as his sovereignty is being violently undone.

Ceremonial Use

At the ceremony, the cloak is handed to a monk, who puts it around Duncan’s shoulders. The gesture accompanies a religious confirmation of Duncan’s sovereign power: the monk blesses him and declares that no harm will come to him so long as he wears it. The cloak is therefore not merely a mark of rank; its place in the rite gives it a stated protective significance, conditional on Duncan continuing to wear it.

Removal and Exposure

That condition becomes sharply visible when the three attackers close in on Duncan. As he retreats up the steps toward the throne, Lady Duncan snatches the cloak from him. Duncan tries to cover his body with his arms and feels naked and exposed without it. The change is immediate: what had been placed over his shoulders as protection is taken away at the moment he is most vulnerable.

Regalia and the Fall of Sovereignty

The cloak’s removal coincides with the scattering of Duncan’s other emblems of rule. His scepter falls one way and his crown the other, while Macbett pulls him down. The staging separates the objects—the cloak, scepter, and crown—as they cease to protect or sustain Duncan. The cloak’s significance lies in that reversal: a blessing tied to wearing it is followed by its forcible removal, and the exposed king is brought down as his regalia falls around him.
