Büttner-Wobst notes (519) that Schweighäuser thought that a possible context of the fragment is the speech by Perseus of Macedon (ca. 212 - 166 BCE) to his soldiers (cf. Livy 42.61, web address 1) following their rout of the Roman forces at the Battle of Callinicus (a hill near the Roman encampment (cf. Livy 42.58, web address 2) at Tripolis Larisaia, Barrington Atlas map 55 grid D1; about 10km east of Larissa, Thessaly; 171 BCE), during the Third Macedonian War (171-168 BCE); cf. Burton 128-132.
