Nummius Aemilianus Dexter

Nummius Aemilianus Dexter ( 380–395), often erroneously called Flavius Lucius Dexter, was a figure of the late fourth century, reported as a historian, and acquainted with St Jerome. He was the son of St Pacian, an imperial office-holder, and dedicatee of a work of Jerome, the De Viris Illustribus. In the nineteenth century there were still references to the Chronicle as genuine, e.g. its inclusion in Volume 31 of the Patrologia Latina.

There is a second work attributed to him, In prophetam Danielis de quatuor animalibus ("Against the prophet Daniel on the four animals").

The real Dexter was the author of a genuine work known as the Omnimoda Historia (which St. Jerome refers to in On Illustrious Men 132, but claims he had not read it) but while historians are agreed that it is to be distinguished from the Chronicle of Pseudo-Dexter, the exact nature of the work is debated. Given Jerome's similar phraseology in reference to Eusebius' Chronicle, the work has been seen as either a continuation or translation of that work.
