Apparently both the consular lists for this year and the text of Livy alike became confused, though it is clear that two colleges of Consuls were once{7} named in Livy. If Valerius and Lucretius are referred to the college of 507 which Livy omits (see 507) the total number of consulships of Valerius as reported in Livy will accord with the general tradition, but P. Lucretius is either a corruption of Sp. Larcius or is inserted instead of Horatius through confusion with Valerius' colleague in 508 and 504, T. Lucretius. (Broughton MRR I)
