I dont know the answer, i suggested alcor and mizar because it was observed before william herschel discovered other binaries.I think they were first visual binaries ever discovered.
Alcor and Mizar have been known as a visual double since before antiquity.

But there proper motion was also studied by ancient indians.
I don't see how. They are WAAAY too far apart for their orbital motion around each other to be noticeable over a few thousand years. Especially before the invention of the telescope in the 1600's. It's likely that any reference to them moving around each other is based on something other than visual observation.
