Livy, From the Founding of the City… (1905)
“ Macedonia, as Perseus saw, was only open to attack from Illyria. The Illyrians were becoming restless themselves and they were allowing a passage to the Romans; Perseus thought, therefore, that if he crushed their next neighbours, King Gentius, who had long been wavering, might become his ally. Accordingly he marched to Stuberra with a force of 10,000 infantry, some of whom belonged to the phalanx, 2000 light-armed troops and 500 cavalry. ”
