My Fibonacci book got an unexpected plug today on the website of the nationally syndicated public radio program Harmonia Early Music. The program occasionally chooses dates in history at random and provides a little history and music about what was going on then.

Harmonia’s chosen year 1250 was a bad one for Fibonacci. It’s the year he most likely died, during an occurrence of the plague in Pisa, Italy. The program’s audio is lushly scored; you can check out the mp3 at the link above. The written transcript is here, along with the link to my book.
