Polybios 38.1-3.8
The 38th book contains the completion of the disaster of the Hellenes. For though both the whole of Hellas and her several parts had often met with mischance, yet to none of her former defeats can we more fittingly apply, the name of disaster with all it signifies than to the events of my own time. ...In the time I am speaking of a common misfortune befell the Peloponnesians, the Boiotians, the Fokians, the [Eub]oians, the Lokrians, some of the cities on the Ionian Gulf, and finally the Macedonians.
