I think you may be overlooking the dhow with it's lateen rigs from
some 2000 years ago.

You may be overlooking the fact the had no keel and sailed at best with
the
wind abeam, not into the wind. Show me proof.

You may have overlooked the fact that many boats without keels have
very good windward performance.
My cats and dhows with leeboards included

Question: if a square rig's sails could be turned 90 deg (with the wind
abeam), and a centerboard or sideboard were dropped to resist sideways
movement, and enough ballast were present to prevent capsize, could the boat
move in a track that is more perpendicular relative to the wind? I.e., is it
only the "lift" that makes a boat move forward when not going downwind?
