My spirit turned, oh! oftener than it might.
Thus much and more; and yet thou lov'st me not
And never wilt! Love dwells not in our will
Nor can I blame thee, though it be my lot
To strongly, wrongly, vainly love thee still."
The word "wrongly" shows that Mary was married.
She is referred to by him in his last letters.
The "Last Words to Greece," published posthumously, refer to Mary, and contain the same sentiment of his famous poem, "Oh talk to me not of a name great in story," written in 1821, and also posthumously published. He cares more about Mary's love than for the honours he would attain as hero in the Grecian War. He exclaims he is a fool of passion, and that the maddening fascination of Mary can depress him low if she frowns.
The celebrated poem to the Po River, sent May 8, 1820, to Murray, was inspired by "private feelings and passions"; he wrote Murray that it must not be published. The river Po in the poem really refers to the river Trent, in England, with memories of which Mary was bound to him.
