11. Later ancient protreptics:

{Beyond Aristotle’s Protrepticus: post-classical protreptic discourse mostly offers little evidence about Aristotle’s work. In review: Peripatetic protreptic; Epicurean and Stoic protreptic; specialized protreptic discourses to the arts, including Galen’s Protrepticus; protreptics in Cicero; Seneca’s Protrepticus and protreptic tropes; other Latin exhortations; other ancient Greek protreptics, including Ptolemy’s Almagest, and various commentators in late antiquity; and Christian protreptics. The protreptic arguments of Iamblichus are the main sources of evidence for Aristotle’s Protrepticus; and the protreptics of Cicero also supply some corroboration; but other material of the later ancient protreptic tradition supply only slight and indirect evidence.}
