Priscus wrote in the Greek language a history of the Byzantine Empire in eight books. The books probably covered the time from the rise of Attila the Hun to the rise of Emperor Zeno, or from 433 up until 474 AD. Priscus was very influential in the empire and his books were used by different writers: Emperor Constantine VII Porphyrogenitus ("Excerpta de Legationibus"), Evagrius Scholasticus, Cassiodorus, Jordanes, and author of the Suda. The style of Priscus's writing is direct and his work is considered a trustworthy account of Attila the Hun, his court, and the admission of the Roman ambassadors. Priscus relied on a style of historiography that was part of an ancient Greek tradition dating back to the 5th century BC.
