An Inscription for the Statue of Dido

Oh most unhappy Dido!
Unhappy wife, and more unhappy widow!
Unhappy in thy mate,
And in thy lover more unfortunate:
By treason th' one was reft thee;
By treason th' other left thee.
That left thee means to fly with;
This left thee means to die with.
The former being dead,
From brother's sword thou fliest:
The latter being fled,
On lover's sword thou diest.
