The expedition of the consul of 639, Marcus Aemilius Scaurus, against the Taurisci(12) presented more the character of a war of conquest. He was the first of the Romans to cross the chain of the eastern Alps where it falls lowest between Trieste and Laybach, and contracted hospitable relations with the Taurisci; which secured a not unimportant commercial intercourse without involving the Romans, as a formal subjugation would have involved them, in the movements of the peoples to the north of the Alps. Of the conflicts with the Scordisci, which have passed almost wholly into oblivion, a page, which speaks clearly even in its isolation, has recently been brought to light through a memorial stone from the year 636 lately discovered in the neighbourhood of Thessalonica. According to it, in this year the governor of Macedonia Sextus Pompeius fell near Argos (not far from Stobi on the upper Axius or Vardar) in a battle fought with these Celts; and, after his quaestor Marcus Annius had come up with his troops and in some measure mastered the enemy, these same Celts in connection with Tipas the king of the Maedi (on the upper Strymon) soon made a fresh irruption in still larger masses, and it was with difficulty that the Romans defended themselves against the onset of the barbarians.(13) Things soon assumed so threatening a shape that it became necessary to despatch consular armies to Macedonia.(14) A few years afterwards the consul of 640 Gaius Porcius Cato was surprised in the Servian mountains by the same Scordisci, and his army completely destroyed, while he himself with a few attendants disgracefully fled; with difficulty the praetor Marcus Didius protected the Roman frontier. His successors fought with better fortune, Gaius Metellus Caprarius (641-642), Marcus Livius Drusus (642-643), the first Roman general to reach the Danube, and Quintus Minucius Rufus (644-647) who carried his arms along the Morava(15) and thoroughly defeated the Scordisci. Nevertheless they soon afterwards in league with the Maedi and the Dardani invaded the Roman territory and plundered even the sanctuary at Delphi; it was not till then that Lucius Scipio put an end to the thirty-two years' warfare with the Scordisci and drove the remnant over to the left bank of the Danube.(16) Thenceforth in their stead the just-named Dardani (in Servia) begin to play the first part in the territory between the northern frontier of Macedonia and the Danube.
