I

This Riddle rede or die,
Says History since our Flood,
To warn her sons of power:—
It can be truth, it can be lie;
Be parasite to twist awry;
The drouthy vampire for your blood;
The fountain of the silver flower;
A brand, a lure, a web, a crest;
Supple of wax or tempered steel;
The spur to honour, snake in nest:
’Tis as you will with it to deal;
To wear upon the breast,
Or trample under heel.
