Riddle 83

Wise was my ancestry,
* * *
dwelt in cities,
after that fire's
* * *
* * *
* * *
with life surrounded,
with fire purified.
Now to me hostile *
earth's brother,
who to me was first
of men as a snare.
I full well remember,
who my ancestry,
my origin, scatter'd
all from their home ;
I may not him injure,
but I him into captivity
sometimes drive,
wide o'er the plains.
I have many wounds,
in mid-earth
no small power,
but I must conceal
from every man
my dark power
of precious craft,
my journey.
Say what I am call'd.
