" Unclean. They were to disguise themselves as outcasts, untouchables, and so get away. She knew all about these wretched outcasts. They handled the dead and were unclean. They were supposed to be possessed by devils, and anyone coming in contact with them was also bedeviled. They were not allowed to touch food and had to eat what was thrown to them from the ground like dogs. They must enter no house and speak to neither man nor woman of the clean. They were dressed in rags and daubed from head to foot with a red paint made from stinking shark oil and red ochre mixed, red being the funereal color. If they were not insane to start with, they soon became so. "
