Or like an opiate, which brings troubled rest,
Or none; or like—like nothing that I know
Except itself;—such is the human breast;
A thing, of which similitudes can show
No real likeness—like the old Tyrian vest
Dyed purple, none at present can tell how,
If from a shell-fish or from cochineal.
So perish every Tyrant’s robe piece-meal!
