In 241 BC, the Romans created the Quirina and Velina tribes, bringing the total number of tribes to thirty five.1 As the thirty five tribes were created from the Pythagorean 6:8:9:12 tetrachord, the Romans cannot increase the number of tribes beyond thirty five tribes. However, once established the Pythagorean system was designed to permit the Romans to increase the size of the tribes, which did occur for the first time in 228 BC. How this was accomplished is explained by Varro when he wrote that a century was originally one hundred men but “when it doubled, it kept is name, just as the tribes…still keep the same name though their number has been multiplied.”2 After the tribal expansion, the thirty five tribes numbered 252,000 men broken into the following: 35 Tribes Class

Iuniores Seniores Total
Class I 63000 12600 75600
Class II 21000 4200 25200
Class III 21000 4200 25200
Class IV 21000 4200 25200
Class V 46200 9240 55440
Class VI 25200 5040 30240
Cavalry 12600 2520 15120
Total 210000 42000 252000

Preparations for the increase of the thirty five tribes could have begun in 232 BC. In that year the Romans made extensive land settlements of territory taken from the Celts. 3 In 225 BC, in response to Rome’s occupation of their territory, the Celtic peoples, the Insurbes, Boii and Gaesatae made war on Rome.4 In order to meet this crisis, the Romans conducted a levy and found those Romans and allies able to bear arms numbered more than 700,000 infantry and 70,000 cavalry.5 Polybius reports that the Romans and Campanians numbered 250,000 infantry and 23,000 cavalry for a total of 273,000 men.6 By subtracting the 210,000 iuniores in the thirty five tribes from the 250,000 Romans and Campanians, this leaves a total of 40,000 Campanian infantry
