Coal of a permanent brazier of coal on the altar of Minerva at Aquae Sulis (modern day Bath), although in fact easily accessible surface coal from what became the Somerset coalfield was in common use in quite lowly dwellings locally.

Aquae Sulis cuamiun ai" "The affixed – Deuina, Deieda, Andagin, (and) Uindiorix – I have bound" An alternative translation based on a much better knowledge of the Celtic languages is the following: "May I, Windiorix for/at Cuamena defeat (alt.

This is a superior, though still uncertain, translation in that it takes into account the nominal cases of the nouns: "Windiorix" (alt. "Windorix") - nominative masculine (subject), lit. "fair-headed" ("windo") "king" ("rix"); "Dewina Deieda" - nominative/vocative feminine "divine Deieda"
