With some minute difference, the most learned critics, Lucas Holstenius, Schelestrate, Ciampini, Bianchini, Muratori, (Prolegomena ad tom. iii. pars i.,) are agreed that the Liber Pontificalis was composed and continued by the apostolic librarians and notaries of the viiith and ixth centuries; and that the last and smallest part is the work of Anastasius, whose name it bears. The style is barbarous, the narrative partial, the details are trifling - yet it must be read as a curious and authentic record of the times. The epistles of the popes are dispersed in the volumes of Councils.
