Of Hydra presence and Stymphalian beak,
Whose quarry is unseasoned youth, who seek
By subtle snares the Infant's steps to trip,
And catch the Minor in their harpy grip.
To his Twelve Labours, against monsters grim,
Who might have lived in safety but for him,
To snare, to slay, to humbug, and to cozen,
Herschelles, just to make a baker's dozen,
Adds a Thirteenth!
A wily, wicked wight,
