Hellenica simply means writings on Greek (Hellenic) subjects. Several histories of fourth-century Greece, written in the mold of
Thucydides or straying from it, have borne the conventional Latin title
Hellenica. The surviving
Hellenica is an important work of the
Greek writer
Xenophon and one of the principal sources for the final seven years of the
Peloponnesian War not covered by
Thucydides, and the war's aftermath.
