The collection comprises the following speeches: • by
Pliny the Younger. It was originally a speech of thanks (
gratiarum actio) for the
consulship, which he held in 100, and was delivered in the
Senate in honour of Emperor
Trajan. This work, which is much earlier than the rest of the collection and geographically anomalous, probably served as a model for the other speeches. Pliny was a popular author in the late 4th century—
Quintus Aurelius Symmachus modeled his letters on Pliny's, for example—and the whole collection might have been designed as an
exemplum in his honor. He later revised and considerably expanded the work, which for this reason is by far the longest of the whole collection. Pliny presents Trajan as the ideal ruler, or
optimus princeps, to the reader, and contrasts him with his predecessor
Domitian. • by
Pacatus in honour of Emperor
Theodosius I, delivered in
Rome in 389. • by
Claudius Mamertinus in honour of Emperor
Julian, delivered in
Constantinople in 362, also as a speech of thanks at his assumption of the office of consul of that year. • by
Nazarius. It was delivered in
Rome before the Senate in 321 at the occasion of the fifteenth anniversary of the accession of
Constantine I and the fifth anniversary of his sons
Crispus and
Constantine II (emperor) becoming
caesares. The speech is peculiar because none of the honoured emperors was present at its delivery, and because it celebrates Constantine's victory over
Maxentius (at the
Battle of Milvian Bridge) in 312, avoiding almost any reference to contemporaneous events. • from the year 311, delivered in
Trier by an anonymous orator, who gives thanks to Constantine I for a tax relief for his home town
Autun. • by an anonymous (yet different) author, also delivered at the court in Trier in 310, at the occasion of Constantine's
quinquennalia (fifth anniversary of accession) and the founding day of the city of Trier. It contains the description of an appearance of the sun god
Apollo to Constantine, which has often been regarded as a model of Constantine's later
Christian vision. Also, the speech promulgates the legend that the emperor
Claudius II was Constantine's ancestor. • by an anonymous author delivered at the wedding of Constantine to
Maximian's daughter
Fausta in 307, probably also at Trier, and it therefore contains the praise of both emperors and their achievements. The bride and the wedding feature only to a very limited degree in the oration. • celebrates the reconquest of
Britain by
Constantius Chlorus,
caesar of the
tetrarchy, from
Allectus in 296. The speech was probably delivered in 297 in Trier, then the residence of Constantius. • is the second speech in the collection where the emperor was not present. It is by
Eumenius, teacher of
rhetoric at Autun, and is directed at the governor of the province of
Gallia Lugdunensis. It was most probably delivered in 297/298, either in Autun or
Lyon. Apart from its main subject, the restoration of the school of rhetoric at Autun, it praises the achievements of the emperors of the tetrarchy, especially those of Constantius. • from the year 289 (and therefore the earliest of the
late antique speeches of the collection), at Trier in honour of Maximian at the occasion of the founding day of the city of Rome. According to a disputed manuscript tradition, the author was a certain Mamertinus, who is identified with the author of the next speech. • from 291, also at Trier to Maximian, at the emperor's birthday. It is often attributed to Mamertinus, probably
magister memoriae (private secretary) of Maximian, though the text is corrupt and the authorship not entirely certain. • by an anonymous orator, delivered in Trier in 313, celebrating (and describing extensively) Constantine's victory over Maxentius in 312. The author of this panegyric makes heavy use of Virgil. == Themes ==
