Tincomarus

Tincomarus (a dithematic name form typical of insular and continental Celtic onomastics, analysable as tinco-, perhaps a sort of fish + maro-, "big") was a king of the Iron Age Belgic tribe of the Atrebates who lived in southern central Britain shortly before the Roman invasion. His name was previously reconstructed as Tincommius, based on abbreviated coin legends and a damaged mention in Augustus's Res Gestae, but since 1996 coins have been discovered which give his full name.
