(With what truth may I say--
Roma! Roma! Roma!
Non e piu come era prima!)

I.
My lost William, thou in whom
Some bright spirit lived, and did
That decaying robe consume
Which its lustre faintly hid,--
Here its ashes find a tomb,
But beneath this pyramid
Thou art not—if a thing divine
Like thee can die, thy funeral shrine
Is thy mother’s grief and mine.

II.
Where art thou, my gentle child?
Let me think thy spirit feeds,
With its life intense and mild,
The love of living leaves and weeds
Among these tombs and ruins wild;--
Let me think that through low seeds
Of sweet flowers and sunny grass
Into their hues and scents may pass
A portion--

Percy Bysshe Shelley
