Pyrrhus built several places, such as ANTIGONIA (Antigónia, according to the Macedonian pronunciation), named after his wife Antigone, by the side of the passes leading from Illyricum. You will remember my saying, that Illyricum, from the Aöus, till far up into the mountains, is a hilly country. The στενὰ τῆς Ἀντιγονείας (_claustra Epiri_) lead from thence into the mountains of Epirus. The spot is of great importance in the wars of Pyrrhus and his son Alexander against Macedonia; and in universal history, these _claustra_ are celebrated in the expedition of the Romans against Philip of Macedonia. After the Romans had endeavoured in vain, with the Aetolians their allies, to advance into Macedonia through Illyricum and across the Candauian mountains, in order to attack the Macedonians, they marched through Epirus. Philip opposed them for a long time; but it has been proved that all passes are invincible to those only who make a direct attack upon them; they present no difficulty to any one who does not mind spending some time in marching round them. This the Romans did. The Macedonian army then retreated, being compelled to abandon Epirus. Argyrocastro at present occupies nearly the same site. BERENICE also was built by Pyrrhus, and he named it after his great patroness, Berenice, the wife of Ptolemy Soter, and the mother of his own wife Antigone. I cannot refrain here from making a short grammatical observation. We generally speak of Molossians, and the Roman authors, too, said _Molossi_, but the Greeks said Μολοττοί, which is the genuine ancient pronunciation and not an Atticism. As people in later times imagined that it was only an Attic form, they changed the name into _Molossi_. From Lucian’s _Judicium Vocalium_, however, we see, that ττ was essentially Thessalian, and the Thessalians were only Hellenised Epirots. Aristotle, who never Atticizes, always writes ὁ τῶν Μολοττῶν βασιλεύς. I have as yet mentioned to you only three tribes, and I might add many more, but will notice only the most important. In the north we have the ATINTANIANS on the slope of the Epirot mountains towards Illyricum. They were, properly speaking, not so completely subdued by the Illyrians as the Hyllians and Pelagonians who lived farther north, but they were subject only ἐς φόρου ἀπαγωγήν. The Atintanians were the first people that yielded obedience to the Romans on their crossing the Adriatic.
