Metrobius (Ancient Greek: Μητρόβιος; lived 1st century BC) was an actor and a talented singer,[1] in the Roman Republic.
"It was this laxity, as it seems, which produced in him [Sulla] a diseased propensity to amorous indulgence and an unrestrained voluptuousness, from which he did not refrain even in his old age, but continued his youthful love for Metrobius, an actor."
"However, even though he [Sulla] had such a wife at home, he consorted with actresses, harpists, and theatrical people, drinking with them on couches all day long.
For these were the men who had most influence with him now: Roscius the comedian, Sorex the archmime, and Metrobius the impersonator of women, for whom, though past his prime, he continued up to the last to be passionately fond, and made no denial of it."
In Raffaello Giovagnoli's novel Spartacus (1874) an actor named Metrobius accidentally overhears a conversation concerning a gladiator's plot and informs Julius Caesar about it.
