This volume is the last of three with Aristophanes fragments that have survived without specifying a comedy title (Incertarum fabularum fragmenta) or whose authenticity was doubted (Dubia). The mostly very short fragments handed down in lexicographic works often provide unique insights into disparate topics of Greek literature, history, culture and society, which go far beyond the purely formal level. All fragments and also the texts of the bearers of tradition are discussed critically.
