modern sails spun off mechanical flight technology?

The most efficient sail design of all time was developed in Northern
Italy. The design was lost during the early Renaissance, only to be
recently uncovered during and archeological dig in a shallow bay. The
sails reused the wind many times over with each "stage" adjusted for the
reduced wind velocity. The sails are a series of "slats" with multiple
gaps and adjustable angles of attack. They are referred to as Venetian
Sails.
Now that was a very illuminating little essay
