1. Eutrop. ix. 19 [13]. Victor in Epitome [c. 39]. The town
seems to have been properly called Doclia, from a small
tribe of Illyrians (see Cellarius, Geograph. Antiqua, tom.
i. p. 393); and the original name of the fortunate slave was
probably Docles; he first lengthened it to the Grecian
harmony of Diocles, and at length to the Roman majesty of
Diocletianus. He likewise assumed the Patrician name of
Valerius, and it is usually given him by Aurelius Victor.
