 1    IV|    tumbled headlong to this empty lake;~Our former glory still
 2     V| gaze and some to fight:~The empty air a sound confused did
 3   VII|   threatening battle to the empty sky,~Tears with his horn
 4   VII|      And to their champions empty let remain~ Twixt either
 5  VIII|    breast,~A little by, his empty helm we found~The silver
 6    IX|     filled with devils, and empty hell.~ ~ XVI~The Soldan
 7    IX|    Limbo's prisons got,~The empty air, the hills and valleys
 8     X| took their way on foot,~The empty chariot vanished out of
 9  XIII| thunder;~Hear, you amid the empty air that dwell~And storms
10   XIX|     their fone,~And on this empty conquest let them boast,~
11   XIX|     wanteth one,~But in his empty place some other knight~
12    XX|  and bestrode~The courser's empty back, and forth he rode.~ ~
