Apart from the mention by Cicero of this being the first lex de repetundis, in the passage from the Brutus (see n. 39), and the references to those prosecuted under the lex Calpurnia and the lex Julia in the lex de repetundis inscribed on the Urbino fragments (hereafter ‘Epigraphic Law’) and a passing reference by Tacitus, there is nothing more in the sources to elucidate the nature or content of the lex Calpurnia de pecuniis repetundis. That this is the limit of our information, see e.g. Crawford, M.H., ‘Origini e sviluppi del sistema provinciale romano’, in Storia di Roma, 2.1 (Torino 1990) 101Google Scholar; Ferrary, J.-L., ‘Patroni et accusateurs dans la procedure de repetundis’, Rev. hist, droit. 76.1 (1998) 30Google Scholar.
