Inspired by a previous question on the historical treatment of the disabled, I wonder if there are any written sources from Egyptian, Mesopotamian, Babylonian and civilizations from before 1400BCE about the following things:
What sorts of people would the early civilizations consider "handicapped", that is, distinguished from "normal" members of society due to what we would consider a disability today? (Based on contemporary textual sources, not archaeological inference.)
How were these people treated? (May use textual sources and archaeology.)
