Behold, sir King,
The wronged Duke of Milan, Prospero.
For more assurance that a living prince
Does now speak to thee, I embrace thy body
And to thee and thy company I bid
A hearty welcome.
– William Shakespeare
The Tempest, Act 5, Scene 1. Prospero identifies himself to King Alonso as the wronged Duke of Milan. And he makes it clear to Alonso that he is not a ghost by embracing him and bidding him and his company an ironic hearty welcome.
