Hellenica by Xenophon - simply means writings on Greek (Hellenic) subjects. Several histories of 4th-century Greece, written in the mould of Thucydides or straying from it, have borne the conventional Latin title Hellenica. The surviving Hellenica is an important work of the Ancient Greek writer Xenophon and one of the principal sources for the last seven years of the Peloponnesian War not covered by Thucydides, as well as the war's aftermath.Xenophon's Hellenica is a Classical Greek historical narrative divided into seven books that describe Greco-Persian history in the years 411-362 BC. The first two books narrate the final years of the Peloponnesian War from the exact moment in time at which Thucydides' history ends. The remaining books, three to seven, focus primarily on Sparta as the dominant city-state in Greece after the Peloponnesian War's end; continuing into the period known as the Theban hegemony following Sparta's defeat at the battle of Leuctra.Scholars believe the first two books were written at a much earlier time period when Xenophon was still living in Athens; while books three to seven were written after Xenophon was banished from Athens and living in Sparta. The work ends with a summation by Xenophon that his history has ended, but another historian may continue it. The Hellenica is the only primary source for the period from the end of the Peloponnesian War until the time of Alexander.
