 In the obscure and corrupt fragment of Sextus Pomponius' "de Origine Juris", after mentioning Sextus and Publius Aelius and Publius Atilius, the author proceeds to speak of the two Catos.This passage seems to speak of a Cato before the Censor, but Pomponius wrote in paragraphs, devoting one to each succession of jurists, and the word "Deinde" commences that of the Catos, though the Censor had been mentioned by anticipation at the end of the preceding paragraph.From the Catos, father and son, the subsequent jurists traced their succession.
