Piers Gaveston is a favorite of the king and most likely his lover.
O miserable and distressed queen!
Would, when I left sweet France, and was embarked,
That charming Circe, walking on the waves,
Had chang'd my shape! or at the marriage-day
The cup of Hymen had been full of poison!
Or with those arms, that twin'd about my neck,
I had been stifled, and not liv'd to see
The king my lord thus to abandon me!
Like frantic Juno, will I fill the earth
With ghastly murmur of my sighs and cries;
For never doted Jove on Ganymede
So much as he on cursed Gaveston:
But that will more exasperate his wrath;
I must entreat him, I must speak him fair,
And be a means to call home Gaveston:
And yet he'll ever dote on Gaveston;
And so am I forever miserable.
