DENNIS VAC

Vernacular English form, based on French Denis, of the Greek name Dionysios, Late Latin Dionisius, which was borne by several early Christian saints, including St Denis, a 3rd-century evangelist who converted the Gauls and became a patron saint of Paris. It was on his account that the name was popular in France and was adopted by the Normans. In classical times, the name was an adjective denoting a devotee of the god Dionysos, a relatively late introduction to the classical pantheon; his orgiastic cult seems to have originated in Persia or elsewhere in Asia.
