The only way anyone could have come anywhere close to tuning a piano type instrument to something close to ET before the late 1800's (if indeed not later then that) was if they tuned the temperament to some exterior pitch source... note for note... such as a monochord for example and then tuned octaves upwards and downwards. That probably was possible to do... and indeed some of the stuff I have seen written between advocates of monochords and advocates of the old style of ear tuning (which relied on a highly trained sense of pitch) resemble often enough discussions between todays modern ETD tuners and todays "ear tuners" (which are quite different from yesteryears ear tuners in that these later are in reality not ear tuners at all, rather they are beat counters). As far as Bach and ET is concerned. The closest Bach could have gotten to ET was limited to the closest any tuner could have matched a monochord to a piano, which in turn was dependant upon how good the monochord was (relative to ET) in the first place. More then likely Bach was more concerned with demonstrating what Jorgensen terms "non restrictive" temperaments in his work relative to "ET".
