Headcoverings span across time, culture, and place. Though many associate them exclusively with one group or another, the truth is that there are many, many ladies from all traditions who choose to wear them!
"First scientist" and muslim Alhazen ibn al-Haytham (965-c.1040) rejected Aristotle's theory that physical forms enter the eye to plant images in the head and Euclid and Ptolemy's theory that rays from the eyes went out and "scanned" or "detected" objects. Instead, he opted for light coming from external objects to enter the eye, carrying an image of the object being looked at....and he theorized all this while in prison!! His diagram of the eye still contain terms we use today.
