430 BC

Histories (Herodotus)

Herodotus brings the Histories toward its final form

A single aside about three executed envoys proves the book was still changing almost twenty years after the date the listing gives.

The date is impossible

Herodotus cannot have completed the surviving Histories in 449 BCE. The text refers back to the Athenian execution of Spartan envoys and Aristeas, an event dated to 430 BCE — he interrupts a story set in Xerxes's time to say it happened "many years after" the invasion, then returns to his narrative.

Other internal references reach the opening of the Peloponnesian War in 431–430, which is why the Perseus biographical survey concludes he was still working as late as 430.

The listing appears to confuse the traditional 449 end of the Greco-Persian Wars with the date the man writing about them put down his pen.

And completion may not be a date at all

Scholarly proposals for publication range from roughly the later 430s or 426/425 BCE to still later. No exact completion day is recoverable.

Publication may not have been a single event: whether the work circulated in readings, installments or a final written edition is uncertain.

The division into nine books named for the Muses is later than Herodotus and should not be read back into his own presentation.

What the work is

The proem states the purpose: to preserve notable deeds by Greeks and non-Greeks and to explain why they fought one another. The main narrative culminates in the failure of Xerxes's invasion and the Greek operations of 479 BCE.

It is not a chronicle of battles. Much of it is geography, ethnography, custom and political explanation, and it devotes extensive attention to mainland Greece as well as to the Persian world; reading it as a simple contest of Persian slavery against Athenian freedom is an interpretive oversimplification.

Herodotus often preserves incompatible stories and tells the reader which he believes — or declines to choose. The author's manuscript is lost, and the text is reconstructed from medieval codices and substantially earlier papyrus fragments.
