Commentarius, Commentarii

ὑπομνήματα). Properly notes or note-books. Hence the word acquires a variety of meanings, of which the most important are the following:


Commentarii domestici, or family memorials, the records of events interesting to the members of particular families.


The “memoirs” drawn up by public men as to events in which they had taken part. See above.


Memoranda kept by different departments of the public service, the officials in charge of them being known as a commentariis.


In towns a register kept of the official acts of the municipal authorities. We have interesting extracts from the commentarii of Caeré in an inscription in the Museum at Naples (Wilmanns, 2083).


The unofficial record of recent events at Rome, sent by Caelius to Cicero in Cilicia, is called by him commentarii rerum urbanarum (Ad Fam. viii. 2, 2).


The record of the daily occurrences at court kept in commentarii diurni (Suet. Aug. 64), a kind of private diary, which must be distinguished from the formal acta and also from


Commentarii principis, the register of the emperor's official decisions (Plin. Ep. x. 106) and of accusations brought before him (Calig. 15).


Tacitus once ( Ann. xv. 74) speaks of commentarii senatus, by which he can hardly mean anything but the acta senatus. See Acta.
