When Cassiano dal Pozzo, the Pope’s personal assistant, returned to the Vatican from Spain in 1626, he brought with him a Mexican manuscript on natural history, the Libellus de medicinalibus Indorum herbis.

It is well known that you cannot divide a number by zero. Math teachers write, for example, 24 ÷ 0 = undefined. They use analogies to convince students that it is impossible and meaningless, that “you cannot divide something by nothing.” Yet we also learn that we can multiply by zero, add zero, and subtract zero. And some teachers explain that zero is not really nothing, that it is just a number with definite and distinct properties. So, why not divide by zero? In the past, many mathematicians did.

But few know that it was first asked in a novel. And even fewer know that the author’s working drafts of that novel can be seen today in the Harry Ransom Humanities Research Center at the University of Texas at Austin.

For nearly 30 years, historians have debated about the use of former slave narratives as a “valid” historical source. Scholars question the authenticity of interviews collected in the 1930s, often by white Works Progress Administration (WPA) field workers.
