Animals are divided into:
• those that belong to the Emperor,
• embalmed ones,
• those that are trained,
• suckling pigs,
• fabulous ones,
• stray dogs,
• those included in the present classification,
• those that tremble as if they were mad,
• innumerable ones,
• those drawn with a very fine camelhair brush,
• those that have just broken a flower vase,
• those that from a long way off look like flies.
from the Celestial Emporium of Benevolent Knowledge,
by Jorge Luis Borges
Borges' taxonomy is from his 1942 essay The Analytical Language of John Wilkins, which I haven't read, but that's not stopping me from doodling illustrations for it in a battered old sketchbook.
Who are those that belong to the emperor?
Or the embalmed ones?
It's fun to think about, a project to mull over for a long time.
