In ancient Rome, a chief mime or the leader of a mime troupe; also the principal performer in pantomime.
From Greek 'archi-' meaning 'chief' and 'mimos' meaning 'mime,' a term used in Roman entertainment to denote a star performer rather than a regular actor.
Roman mimes were actually hugely popular and could be superstars—the 'archimime' was like the lead member of an improv troupe, and some became so famous they performed for emperors and influenced public opinion.
