Vernostonos
Verostonos (or Vernostonus) was a god in ancient Celtic polytheism, worshipped in Roman Britain. His name links him to alder- trees. Altar-stones raised to him have been recovered in the United Kingdom, such as that at Ebchester in County Durham (RIB 1102, DEO VERNOSTONO COCIDIO VIRILIS GER V S L).1 His association with Cocidius in that inscription suggests that he may have been linked with, or an epithet of, that more widely attested war god.
