Tincomarus (a dithematic name form typical of insular and continental Celtic onomastics, analysable as tinco-, perhaps a sort of fish [cf Latin tinca, English tench] + 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.
GC Boon has suggested that this technical advance was not limited to coinage and represents wider industrial assistance from the Roman Empire.
[4] John Creighton argues, based on the imagery used on his coins, that Tincomarus may have been brought up as an obses (diplomatic hostage) in Rome in the early years of Augustus's reign.
[5] By 16 BC Roman pottery and other imports appear in considerable quantities at Tincomarus's capital of Calleva Atrebatum, today known as Silchester, and it is likely that the Atrebatic king had established trading and diplomatic links with Augustus.
[6] Augustus may have planned to use his ally's ejection as an excuse to invade Britain but other, more pressing foreign policy matters probably persuaded him to postpone the move.
