What is the origin of Roscian?
The English adjective Roscian comes straight from the Latin proper adjective Rosciānus, coined by and used exclusively by Marcus Tullius Cicero (106–43 b.c.) in honor of his older contemporary, mentor, friend, and client, the actor Quintus Roscius Gallus (ca. 126–62 b.c.). Acting was not a respected profession in Rome, but Roscius dignified it and devoted himself to elocution, gesture, and characterization. The Roman general, reactionary politician, and dictator Sulla (138–79 b.c.) even presented Roscius with a gold ring, a symbol of equestrian rank. Roscius instructed the young Cicero in elocution and delivery; Cicero successfully pleaded Roscius’ cause in a civil suit around 76 b.c. (Cicero’s speech Pro Quinto Roscio Comoedo survives); he and Roscius used to engage in friendly contests to see who could express emotion and character better, the actor or the orator. Roscian entered English in the early 17th century.
