Wikipedia indicates that the classic riddle "As I was Going to St Ives" was written at some point in the 1700s or 1800s.
As I was going to St Ives
I met a man with seven wives
Bigamy, however has been illegal in the UK since at least the 1600s and prior to that, a breach of ecclesiastical law.
Why is this man's bigamy not noted upon by the author? Is there any indication why (or how) he even had seven wives in the first place?
As I was going to St Ives
I met a man with seven wives
He was promptly arrested
For a breach of the Bigamy Act 1603
And subsequently executed.
