Grumio is a slave in Plautus' Mostellaria (2nd century BC).

Gremio is a dirty old man in Shakespeare's The Taming of the Shrew (1592).

Gremio is a servant in Konami's Suikoden (1995).

@AncientPLay Despite studying Plautus specifically, and having watched a full Suikoden playthrough in which there were strong opinions on Gremio, I had never made that connection before. Huh!
