When is the first recorded instance of the limerick as a poetic form?

If we're talking about form and rhyme, but not meter, then the earliest recorded limerick (though it was not called that at the time) was written by Thomas Aquinas in the 13th century.

Others to have contributed to the development of the limerick's form include William Shakespeare who penned this drinking song in 'Othello' (Act 2 Sc. III):

And let me the canakin clink, clink;
And let me the canakin clink
A soldier's a man;
A life's but a span;
Why, then, let a soldier drink.

The origin of the final metric form as we know it today is unclear and still debated; as is the etymology of the term 'limerick' itself. What is established is that the modern limerick was popularised by Edward Lear when he published his 'Book of Nonsense' in 1826. Since then the form has been tackled by seemingly every author or poet to date.

There is even a Chat Board for limericks on this site.

Saint Thomas Aquinas (1225-1274) wrote the first limerick sometime in the 13th century:

Sit vitiorum meorum evacuatio
Concupiscentae et libidinis exterminatio,
Caritatis et patientiae,
Humilitatis et obedientiae,
Omniumque virtutum augmentatio

Verbatim translation by Irene Blase:

Let it be for the elimination for my sins,
For the expulsion of desire and lust,
[And] for the increase of charity and patience,
Humility and obedience,
As well as all the virtues..

I would never think of this as a limerick but this is what history is telling me.
