The translator's role as a bridge for "carrying across" values between cultures has been discussed at least since Terence, the 2nd-century-BCE Roman adapter of Greek comedies. The translator's role is, however, by no means a passive, mechanical one, and so has also been compared to that of an artist. The main ground seems to be the concept of parallel creation found in critics such as Cicero. Dryden observed that "Translation is a type of drawing after life..." Comparison of the translator with a musician or actor goes back at least to Samuel Johnson’s remark about Alexander Pope playing Homer on a flageolet, while Homer himself used a bassoon.
