Moccus is a Celtic god who was identified with Mercury. He is the boar- or swine-god of the continental Celtic tribe of Lingones. Moccus was invoked as the protector of boar hunters and warriors. Boar meat was sacred among the ancient Celts, and features in accounts of feasts in Irish mythology. The Lingones, whose tribal center was at modern-day Langres, were a Gaulish tribe located in the area of the rivers Seine and Marne in what is now northeastern France. They were neighbors to the Celto-Germanic tribe of Treveri. Another tribe known as Lingones was located near the mouth of the Po River in northeastern Italy, and were known for agriculture, weaving and metalworking.
