"Purple, yellow, red, and green,
The king cannot reach, nor yet the queen,
Nor can Old Noll, whose power's so great,
Tell me this riddle while I count eight."
"A rainbow."
This nursery rhyme's date is fixed by the reference to Old Noll, the Lord Protector.
"As round as an apple, as deep as a cup,
And all the king's horses can't pull it up."
"A well."
"Humpty Dumpty sat on a wall,
Humpty Dumpty had a great fall;
Three score men, and three score more,
Cannot make Humpty Dumpty as before again."
