Nursery Rhyme. Ccclxxiv. Paradoxes

[Mind your punctuation!]

I saw a peacock with a fiery tail,
I saw a blazing comet drop down hail,
I saw a cloud wrapped with ivy round,
I saw an oak creep upon the ground,
I saw a pismire swallow up a whale,
I saw the sea brimful of ale,
I saw a Venice glass full fifteen feet deep,
I saw a well full of men's tears that weep,
I saw red eyes all of a flaming fire,
I saw a house bigger than the moon and higher,
I saw the sun at twelve o'clock at night,
I saw the man that saw this wondrous sight.
