In his prologue Herodotus establishes a complex relationship with his poetic predecessors and contemporaries. He presents his narrative of the Greco-Persian Wars as simultaneously indebted and opposed to a network of poets, whose Panhellenic cultural prestige he challenges in the innovative medium of prose. Homeric epic is tacitly acknowledged as a model of primary importance: Herodotus adopts the martial subject matter of the Iliad and projects the persona of the peripatetic hero Odysseus. In perpetuating the kleos of fully human warriors rather than their heroic forebears, Herodotus implies that his own medium of prose historiē, committed to writing, will surpass poetry’s ability to perform its traditional function of public commemoration. Herodotus constructs the entire prologue as an ingenious prose priamel, a poetic rhetorical structure that enables him to emphasize important points of contact with and departure from Homeric epic, Sappho’s fragment 16, and the portrayal of Croesus in epinician poetry.
