In ancient Celtic polytheism, Latis is the name of two Celtic deities worshipped in Roman Britain. One is a goddess (Dea Latis), the other a god (Deus Latis), and they are both known from a single inscription each.
The dedication to Dea Latis was found at Birdoswald Roman Fort in Cumbria, England, in 1873. It reads simply:
The E is written as a ||. The stone is now in the Carlisle Museum. She may have been associated with the nearby rivers.[1]
The dedication to Deus Latis, recovered on an altar-stone at the Roman fort of Aballava, Burgh-by-Sands (also in Cumbria) reads:
The altar-stone to Deus Latis was found near an image of a horned god and another dedication to the god Belatucadros.
The name 'Latis' may conceivably be related to the Proto-Celtic words *lati- meaning 'liquor', *lat- 'day', or *lāto- 'lust'.[2]
