Marvin's 1897 Monograph on The Mechanics and Equilibrium of Kites. This work covers the mechanics of kite flight in some detail. Marvin's work examines the forces acting ona kite, and how they interact with those acting on the line and tail. He examines conditions necessary for equilibrium of the kite-line system, as well as the stability of this equilibrium. Had two lined, steerable kites existed in his day, Marvin's work would have perhaps covered the content of this thesis to some extent. Marvin's work succeeds in breaking down the complexity of kite flight so that it can be understood in simple terms." - Ross Hughan Dawson; Kite Turning; thesis from 2011; page 2.
