6th-century Byzantine historians

Marcellinus Comes (died c. 534) was a Latin chronicler of the Eastern Roman Empire. An Illyrian by birth, he spent most of his life at the court of Constantinople. His only surviving work, the Chronicle, focuses on the Eastern Roman Empire.

Procopius of Caesarea (Greek: Προκόπιος ὁ Καισαρεύς Prokópios ho Kaisareús; Latin: Procopius Caesariensis; c.–after 565) was a prominent late antique Byzantine scholar from Palaestina Prima. Accompanying the Byzantine general Belisarius in Emperor Justinian's wars, Procopius became the principal Byzantine historian of the 6th century, writing the History of the Wars, the Buildings, and the Secret History. He is commonly classified as the last major historian of the ancient Western world.

Theophanes of Byzantium (Greek: Θεόφανης ὁ Βυζάντιος; fl. 6th century) was a Byzantine historian.

Peter the Patrician (Latin: Petrus Patricius, Greek: Πέτρος ὁ Πατρίκιος, Petros ho Patrikios; c.–565) was a senior Byzantine official, diplomat, and historian. A well-educated and successful lawyer, he was repeatedly sent as envoy to Ostrogothic Italy in the prelude to the Gothic War of 535–554. Despite his diplomatic skill, he was not able to avert war, and was imprisoned by the Goths in Ravenna for a few years. Upon his release, he was appointed to the post of magister officiorum, head of the imperial secretariat, which he held for an unparalleled 26 years. In this capacity, he was one of the leading ministers of Emperor Justinian I (r. 527–565), playing an important role in the Byzantine emperor's religious policies and the relations with Sassanid Persia; most notably he led the negotiations for the peace agreement of 562 that ended the 20-year-long Lazic War. His historical writings survive only in fragments, but provide unique source material on early Byzantine ceremonies and diplomatic issues between Byzantium and the Sassanids.

John of Epiphania (Greek: Ιωάννης Επιφανεύς) was a late sixth century Byzantine historian.

Liberatus of Carthage (fl. 6th century) was an archdeacon and the author of an important history of the Nestorian and Monophysite controversies in the 5th- and 6th-century Christian Church.

Jordanes (), also written as Jordanis or Jornandes, was a 6th-century Eastern Roman bureaucrat widely believed to be of Gothic descent who became a historian later in life. Late in life he wrote two works, one on Roman history and the other on the Goths. The latter, along with Isidore of Seville’s Historia Gothorum, is one of only two extant ancient works dealing with the early history of the Goths.

John Malalas (Greek: Ἰωάννης Μαλάλας, Iōánnēs Malálas; c. – 578) was a Syrian chronicler from Antioch.

Evagrius Scholasticus (Greek: Εὐάγριος Σχολαστικός) was a Syrian scholar and intellectual living in the 6th century AD, and an aide to the patriarch Gregory of Antioch. His surviving work, Ecclesiastical History (Ἐκκλησιαστικὴ Ἱστορία), comprises a six-volume collection concerning the Church's history from the First Council of Ephesus (431) to the emperor Maurice’s reign until Scholasticus' death.

Nonnosus (Greek: Νόννοσος, Nónnosos) was an ambassador sent by the Byzantine emperor Justinian I to the king of the Axumites (in Ethiopia and parts of the Arabian Peninsula) around 530 CE. He wrote an account of that visit, now lost, that was read and summarized by Byzantine patriarch Photius in Codex 3 of his Bibliotheca. Per that summary, Nonnosus entered Ethiopia through the Red Sea port city of Adulis and journeyed overland to Axum. He described seeing a herd of 5000 elephants in the vicinity of Aua, between Adulis and Axum. Nonnosus' father Abraham had been an ambassador to the Arabs, and his uncle, also named Nonnosus, had been sent on an embassy by the emperor Anastasius I.
