There are two very very short stories about a turtle and a monkey each of whom became famous not because of who they were but the role that destiny had assigned to them to intervene in the lives of two well known Greeks.
The Greek dramatist Aeschylus died when an eagle carrying a turtle in its talons fatally dropped it on his head.
Alexander of Macedon who invaded India and fought a king called Porus died when a monkey bit him. ( I have often wondered if the word porous as in porous borders originated from the name of that king because ever since then India has had porous borders)
But to come back to the turtle and the monkey and the rest of the subalterns in this world, they can change the course of history and we can ignore them at our own peril.
So the next time you see a turtle or a monkey, as creatures and metaphors, remember they can also make a decisive difference.
