Poems (Mitford)/Lines, imitated from the Italian

IMITATED FROM THE ITALIAN. 
Thy youth and beauty all admire,And yet, fair Caroline, I'm free; Thine eyes the coldest heart might fire,Yet harmless dart their rays on me.
While gentle Julia's artless grace My soul with love's soft transport warms, Unmov'd I view thy matchless face,Yet yield to Julia's simple charms.
'Tis that her smile its dimple owes To gaiety devoid of art; Tis that her eyes' mild lustre flows From her own pure and spotless heart.
Thy beauty, fair and haughty maid! Is transient as a summer's day; But Julia's charms can never fade,Her soul will bloom amid decay.
