Within the seven floors of the Brynmor Jones Library, there are over a million books.

A Sonnet has fourteen lines. 7 floors of the library multiplied by two gives fourteen.

Divide each floor into two halves. Take three dice and roll them.

Counting from the shelf closest to the elevator, the first dice will take you to a series of shelves. The second dice will take you to a section. The last dice will pick the correct shelf.

Roll the dice again.

Multiply two of the dice together and (add or subtract) the third. Count your answer in books along the shelf.

Roll the dice again.

Multiply two of the dice together and (add or subtract) the third. Count your answer in pages of the book.

Roll two of the dice.

(Multiply or Add or Subtract) the two dice together. Count your answer in lines of the book.

Write your line down.

Repeat for all seven floors of the library.

Where books are not available, improvise.

Once fourteen lines have been collected, compile them from the seventh floor to the ground.

Clip the lines to be ten syllables. (If brave enough, rearrange to Iambic Pentameter)

Then experiment.

Use lines as whole or restricted to vocabulary within.

No form of Poem is exempt.

As each line you have collected has a numerical equivalent (1-7 or 1-14) Mathematical structures are possible.

Find text in the Library (Gallery cards, conversations etc.) and force your found lexicon into them.

Find other peoples works and force your lexicon into them.

You have successfully used the Brynmor Jones Library to write poetry.
