Un Demostrato e un Antimaco in un papiro laurenziano (PL III/112): nuovo frammento storiografi co o hypomnema erudito?

This paper comprises an edition of a short papyrus fragment in the Biblioteca Medicea Laurenziana (Florence), containing literary texts on both faces. The text on the front contains references to a certain Demostratos, very probably the 5th century BC Athenian demagogue who promoted intervention in Sicily, and to a certain Antimachos, who may be the Athenian politician of that name for whom we have epigraphic testimony: we may therefore hypothesize that this text comes either from a lost historiographical work or from an erudite commentary on the work of a historian. The text on the back, written by another hand, is even more fragmentary, but, due to the mention of a certain Hellanikos, it was probably a work of erudition, maybe related to early Athenian history, as the traces of other words seem to suggest.
