Louisa Stuart Costello - Eastern Song

By the brightness of the morning ray,
By the deepest shades of night—
Thy beauty has not pass'd away;
'Tis ever in my sight.

No sorrow e'er can light on me—
But when, beloved, we part,
My thoughts are bounded all in thee,
Thou Lote-tree* of my heart.

Louisa Stuart Costello
