Some of the prophets in the Old Testament display spectrum like tendencies. The level of detail in descriptions of buildings not yet built, but only imagined, that you see in the Torah, the precision of food laws etc. I'm not saying Moses was aspie, but you can certainly see how those particular traits helped form a nation... if they hadn't had those rigid food laws in the middle of a desert they'd have died. The whole invention of quarantine in the Torah as well. And some of the later prophets as well... I think of Jeremiah, who was compelled to tell the truth despite immense opposition, who, from the sound of it, had only one friend in his life. He said that if he didn't fulfill his mission he felt like his bones burned within him... he continued with his truth telling even at the bottom of a well.
Of course, people did take things much more literally then than they do now, and I'm not trying to retrospectively diagnose people. Just saying that these men in particular struck me as having spectrum like tendencies.
In Irish faery tale and legend someone who had the "sight" would often fit aspie like tendencies. Even in my own personal knowledge, in rural communities in Ireland people on the spectrum have some respect locally, because folks think they know how they fit in. My mother had a cousin, who everyone thought had the sight... he was actually an autistic savant, so far as I can tell. But the point is, he was normalised, and could fit into life, in his own terms.
