The introduction argues that ancient Greek poetry exhibits a particularly acute awareness of change, decay, and ephemerality inherent in mortality. It stresses the fact that these poems have assumed at least two forms of materiality: one in relation to performing bodies and another as inscribed texts. After reviewing prior scholarship in these areas, it looks at definitions of the body and the word ephêmeros in Greek poetry, including Homer, Pindar, and other lyric poets, and in Ps.-Aeschylus’ Prometheus Bound, before offering summaries of the chapters of the book.
