As when a Shepherd of the
Plac'd far amid the melancholy Main,
(Whether it be lone Fancy him beguiles;
Or that aerial Beings sometimes deign
To stand, embodied, to our Senses plain)
Sees on the naked Hill, or Valley low,
The whilst in Ocean  dips his Wain,
A vast Assembly moving to and fro:
Then all at once in Air dissolves the wondrous Show.
