The name Pseudo-Censorinus denotes the anonymous author of an epitoma disciplinarum, also known as Fragmentum Censorini. Manuscripts unanimously transmit this text after the De die natali by Censorinus. Even if, according to scholarly opinion, Censorinus is not the author of the fragmentum, if one wishes to understand both works fully one must take into account their points of contact: it is because of these points of contact that the manuscript tradition of these two texts is a shared one, probably already in Late Antiquity (R.H. Rouse - R.M. Thompson; Cristante). Both the fragmentum and the De die natali focus on scientific disciplines with special attention for the music; they both testify to the teaching practice of the imperial age (Cristante). [S. Musso; translation L. Battezzato]
