Riddle 13

I saw treading the turf
(ten they were in all)
six brethren,
and their sisters with them ;
they had a living soul,
the skins hung,
manifest and visible,
on the room's wall,
of every one ;
not to any of them was it the worse,
nor his side the sorer,
though they so must,
of garment bereft,
by the Guardian of the skies'
powers awaken'd,
with their mouths tear
the variegated leaves.
Clothing is renew'd
for those who, already come forth,
left their ornaments
to lie in their track,
departing the land to tread.
