Commentariolum Petitionis

Commentariolum Petitionis ("little handbook on electioneering"), also known as De petitione consulatus ("on running for the Consulship"), is an essay supposedly written by Quintus Tullius Cicero, c. 65-64 BC as a guide for his brother Marcus Tullius Cicero in his campaign in 64 to be elected consul of the Roman Republic. The essay does not provide any information that a man of politics such as Cicero would not already know, and is written in a highly rhetorical fashion. As such, its authenticity has been questioned.

Many scholars believe that it was not in fact written by Quintus for the purposes proposed, but in fact by a Roman in the Early Roman Empire, between the periods of Augustus and Trajan, as a rhetorical exercise. Such exercises were not uncommon in that time period. Others claim that it was in fact written by Quintus, but with the view to be published, perhaps as a piece of carefully distributed propaganda.

The degree to which it can be used as evidence for the electoral process and the politics of the Late Roman Republic is therefore contested.
