Note 438 — Chapter IV · THE CENTURIES AND THE CLASSES
Reading edition
The principal sources are Cic. Rep. ii. 20. 36; 22. 39; Livy i. 13. 8; 15. 8; 36. 7; 43. 8 f.; Dion. Hal. ii. 13; vi. 13. 4; Pliny, N. H. xxxiii. (9.) 35; Fest. ep. 55; Plut. Rom. 13. On the basis of these sources we could reckon an increase to 1800, 3600, or 5400 according to our assumption as to the number of horsemen to the century; cf. Gerathewohl, Die Reiter und die Rittercenturien, 3-8.
