Lepidus wrote an Epitome of History. Stephanus of Byzantium quotes book 1 on Tegea: the Pythia's two oracles to the Spartans about Arcadia — "you ask me for Arcadia; I will not give it," then the famous lines on Tegea and the bones of Orestes. Book 8 names Scupi in Thrace (ethnic Scupeni). An unplaced fragment spells the ethnic of Buthrotum Boutrotios with tau.
The fragments are collected in Müller's Fragments of the Greek Historians (vol. 4). The dating is uncertain. This is not Marcus Aemilius Lepidus the triumvir.
The work is an epitome of history surviving in a handful of fragments: Spartan oracles about Arcadia, Tegea, and a few ethnic names.
