That the lex Clodia of 58 B.C. repealed either in whole or in part the lex Aelia Fufia of c. 153 B.C. is adequately attested by our ancient authorities and universally admitted by modern scholars. The crux of the question is: was the lex Aelia Fufia wholly abrogated by the lex Clodia, and, if not, precisely what part of the former law was repealed by the legislation of Clodius? Despite the statement of Cicero—‘mitto eam legem, quae omnia iura religionum, auspiciorum, potestatum, omnes leges quae sunt de iure et de tempore legum rogandarum, una rogatione delevit’—which is obviously rhetorical and biased, no one, so far, as the writer knows, holds the view that all clauses of the lex Aelia Fufia were repealed by the lex Clodia. This inquiry, therefore, is an attempt to determine how much of the lex Aelia Fufia the lex Clodia repealed.
