The _Libri Lintei_ (so called because written on linen) are cited by Livy after the old annalist Licinius Macer, by whom they appear to have been carefully studied. These books were kept in the temple of Juno Moneta, but were probably of less importance than the other public records, which were inscribed on rolls of lead. They were obviously a work of no great extent, since Livy, who appeals to them on four different occasions in the space of ten years, just after the degradation of the decemvirs, had not quoted them before, and never refers to them again. There also appear to have been different copies of them which did not exactly agree, and Livy seems far from considering their authority as decisive even on the points on which reference is made to them(124). The _Memoirs of the Censors_ were journals preserved by those persons who held the office of Censor. They were transmitted by them to their descendants as so many sacred pledges, and were preserved in the families which had been rendered illustrious by that dignity. They formed a series of eulogies on those who had thus exalted the glory of their house, and contained a relation of the memorable actions performed by them in discharge of the high censorial office with which they had been invested(125). Hence they must be considered as part of the _Family Memoirs_, which were unfortunately the great and corrupt sources of early Roman history. It was the custom of the ancient families of Rome to preserve with religious care everything that could contribute to perpetuate the glory of their ancestry, and confer honour on their lineage. Thus, besides the titles which were placed under the smoky images of their forefathers, there were likewise tables in their apartments on which lay books and memoirs recording, in a style of general panegyric, the services they had performed for the state during their exercise of the employments with which they had been dignified(126).
