This is a sworn treaty made between us, Hannibal ... and Xenophanes the Athenian ... in the presence of all the gods who possess Macedonia and the rest of Greece.
Histories, VII, 9:4 (Loeb, W.R. Paton)
It is a course which perhaps would not have been necessary had it been possible to form a state composed of wise men, but as every multitude is fickle, full of lawless desires, unreasoned passion, and violent anger, the multitude must be held in by invisible terrors and suchlike pageantry. For this reason I think, not that the ancients acted rashly and at haphazard in introducing among the people notions concerning the gods and beliefs in the terrors of hell, but that the moderns are most rash and foolish in banishing such beliefs.Polybius
How highly should we honor the Macedonians, who for the greater part of their lives never cease from fighting with the barbarians for the sake of the security of Greece? For who is not aware that Greece would have constantly stood in the greater danger, had we not been fenced by the Macedonians and the honorable ambition of their kings?Polybius
All things are subject to decay and change...Polybius
