What is "dulcitius"

Dulcitius was a Roman governor of Macedonia during the reign of the emperor Diocletian, at the turn of the fourth century AD. He is chiefly remembered for his role in a hagiographic tale of the persecution of Christian women in Thessalonika, in 304 AD, and is the subject of an eponymous 10th century drama written in Germany by the secular canoness, Hrotsvitha of Gandersheim, the first known woman playwright.

The name is also associated with a mid fourth century AD Roman soldier who was appointed Dux Britanniarum (or troop commander in Roman Britain for the region around Hadrian's Wall) and praised for his military abilities by the soldier-historian Ammianus.
