Seneca,
Moral letters to Lucilius — Letter 121…
“ Every being is clever in its own line. The skilled workman handles his tools with an ease born of experience; the pilot knows how to steer his ship skilfully; the artist can quickly lay on the colours which he has prepared in great variety for the purpose of rendering the likeness, and passes with ready eye and hand from palette to canvas. In the same way an animal is agile in all that pertains to the use of its body. ”
