The historian Gordon S. Shrimpton further provides an explanation for Xenophon's silence on much of Theban history. He notes that all the surviving contemporary accounts of Thebes during the period of Theban hegemony between 371 and 341 BC were often highly critical; with their failures ridiculed and their accomplishments usually being downplayed or omitted altogether. For instance, the Athenian Isocrates (436–338 BC) in his "Plataicus" (which details the destruction of Plataea by the Thebans), makes no mention of the Theban victory in Leuctra, and harshly reviles Thebes throughout. His later work "Archidamus" mention Leuctra briefly, and only to criticize Thebans as being incompetent and incapable of capitalizing on their rise to power. The same sentiments are echoed by the Athenians Demosthenes (384–322 BC) and Antisthenes (c. 445–365 BC). Xenophon, another Athenian, is the only contemporary who grudgingly notes some Theban accomplishments, and even then, never in-depth and with numerous omissions. His only mentions of Pelopidas and Epaminondas by name, for example, were very brief and shed no light on their previous accomplishments. Indeed, the historians Bruce LaForse and John Buckler have noted that the character and accomplishments of Epaminondas were so unassailable that there is no known hostile account of him in ancient sources. The most unfriendly writers like Xenophon and Isocrates could do was omit his accomplishments in their work altogether.
