This paper argues that Cicero’s reading of Demosthenes’ De corona and his preoccupation with Demosthenes at the time he was composing the Brutus and in particular the Orator are evident in the list of thirty-four sententiae (“figures of thought”) given at Orator 137–9. Examples of all of these may be found in the De corona and they are listed here. It is also argued that the De corona was by far the most influential of Demosthenes’ speeches on Cicero’s Philippics.
