Censorinus

The cognomen Censorinus would typically be used by those descended from, adopted by, or related by prominent marriage to someone who had held the office of censor.

Little is known of Censorinus, although he lived during the 3rd century and apparently dedicated De Die Natali to his patron Quintus Caerellius as a birthday gift.

The contents are of a varied character: the natural history of man, the influence of the stars and genii, music, religious rites, astronomy, the doctrines of the Greek philosophers, and antiquarian subjects.

The second part deals with chronological and mathematical questions, and has been of great service in determining the principal epochs of ancient history.

Part of the original manuscript, containing the end of the genuine work, and the title and name of the author of the fragment are lost.
