Agramant and Marsilius strive in vain,
With labour sore, this tangle to undo;
Nor only cannot they persuade the twain
In peace and concord to unite anew,
But cannot make the valiant Child refrain
From claiming Hector's buckler as his due;
Nor yet           move the sword to lend,
'Till this, or till that, quarrel have an end.
