Riddle 56

I was therein,
where I saw a
creature striving
against wide wounds,
the wood traversing ;
of swords receiv'd
deep gashes :
darts were
an affliction to the creature,
and the wood with engines
fast bound.
Of its feet was
one stationary,
the other suffer'd toil,
mounted in air,
sometimes nigh to land.
The tree was heavy,
on which bright it stood,
hung with leaves.
I saw the sword
of my lord,
where men were drinking,
whose arrows *
bearing into the room.
