telescope 

Art thou a type of beauty, or of power,
Of sweet enjoyment, or disastrous sin?
For each thy name denoteth, Passion flower!
O no! thy pure corolla's depth within
We trace a holier symbol; yea, a sign
'Twixt God and man; a record of that hour
When the expiatory act divine
Cancelled that curse which was our mortal dower.
It is the Cross!

(Sir Aubrey de Vere)
