Mathematical Treasure: Lewis Carroll’s A Tangled Tale

Author(s): 
Frank J. Swetz (The Pennsylvania State University)

The title page for Lewis Carroll’s A Tangled Tale, published in 1885, is shown above. Lewis Carroll was the pen name of mathematician Charles Dodgson (1832-1898). In the years 1882-1885, Carroll wrote a series of whimsical short stories for the British magazine The Monthly Packet. Each story centered about a mathematical puzzle or problem. This collection of stories was published as the book, A Tangled Tale, in 1885. Each story is listed as a “knot” waiting to be untied [solved] by the reader. Answers and solutions to “knots” are given at the end of the book.

The frontispiece of A Tangled Tale is shown above.

The first problem, or Knot 1, “Excelsior,” is presented above in its entirety to be read and solved.


On page 79 of A Tangled Tale, above, the author discussed some incorrect answers to "Knot 1."
