Cicero, pro Archia, IV, 7: Data est civitas Silvani lege et Carbonis: si qui foederatis civitatibus adscripti fuissent, si tum cum lex ferebatur in Italia domicilium habuissent, et si sexaginta diebus apud prætorem essent professi. See also Schol. Bobiensia, p. 353 (Orelli corrects the mistake Silanus for Silvanus); Cicero, ad Fam., XIII, 30; Marquardt, Staatsverwaltung, I, p. 60. Greenidge, Roman Public Life, p. 311 thinks this law did not apply to any but the incolæ of federate communities; Abbott, Roman Political Institutions, p. 102.
Livy VIII, 14, 9: Tiburtes Prænestinique agro multati, neque ob recens tantum rebellionis commune cum aliis Latinis crimen, etc., ... ceterisque Latinis populis conubia commerciaque et concilia inter se ademerunt. Marquardt, Staatsverw., I, p. 46, n. 3, thinks not an æquum foedus, but from the words: ut is populus alterius populi maiestatem comiter conservaret, a clause in the treaty found in Proculus, Dig., 49, 15, 7 (Corpus Iuris Civ., I, p. 833) (compare Livy IX, 20, 8: sed ut in dicione populi Romani essent) thinks that the new treaty was an agreement based on dependence or clientage "ein Abhængigkeits—oder Clientelverhæltniss."
Mommsen, Geschichte des roem. Muenzwesens, p. 179 (French trans, de Blacas, I, p. 186), thinks two series of æs grave are to be assigned to Præneste and Tibur.
