Between 1502 and 1503, Sultan Beyazid II commissioned Leonardo da Vinci to create a bridge across the Golden Horn. Da Vinci's design, which followed the three geometric principles of the pressed-bow, parabolic curve, and keystone arch, would have been the world's longest bridge at the time, but the sultan did not sanction it.
