Imagine if you would a civilization in the far future, one with a few scant records of earth and it's life. Among those is the animals that their remote ancestors had bred for various purposes, a smatteirng of bones, a few fragmentary images and corrupted stories which have endured for tens of millenia in scraps here and there. Among those was a beast raised for it's woolly fur, milk and meat. They cobble together a rough recreation of something vaguely like what is recorded. This image is the result. Despite this, it is more accurate than some artistic recreations made by people who actually saw sheep in real life who used them as festive ornamentation.
