Mogons

Mogons or Moguns was a Celtic god worshiped in Roman Britain and Gaul.

Koch at the University of Wales, the various alternations of the name Moguns derive from the Romano-Celtic dialectal reflexes of Proto-Celtic *mogont-s (a derivative of the Proto-Indo-European root *megH2- "to be great, mighty"), an Indo-European *-nt- -stem cognate with Sanskrit mahānt and Avestan mazant ‘great’.

[1] Altar-stones raised to Mogons have been recovered in the United Kingdom, such as the stones found at the following locations.

Most are datives, to be translated as "to the god": Modern Mainz takes its name from Castrum Moguntiacum, a Roman base placed there.

The inscription at Habitancum identifies the troops stationed at that location as being from the Vangiones, the Gaesati and Rhaeti from Germania Superior.
