As with all previous editions, we have included allusions designed to interest
both the instructor and the student. For example, in just the first two sections
of Chapter 1 are allusions to Pandora, Benjamin Franklin, Hafiz, P. T. Barnum,
John Donne, Emily Dickinson, Persephone, Madonna, the Hindenburg, Steve
Jobs, Thor, Ichabod Crane, Elmo, and Dido.
