As when a child on some long winter's night  
Affrighted clinging to its Grandam's knees  
With eager wond'ring and perturbed delight  
Listens strange tales of fearful dark decrees  
Muttered to wretch by necromantic spell;  
Or of those hags, who at the witching time  
Of murky midnight ride the air sublime,  
And mingle foul embrace with fiends of Hell:  
Cold Horror drinks its blood! Anon the tear  
More gentle starts, to hear the Beldame tell  
Of pretty babes, that loved each other dear,  
Murdered by cruel Uncle's mandate fell:  
Ev'n such the shiv'ring joys thy tones impart,  
Ev'n so thou, Siddons! meltest my sad heart!
Charles Lamb
