Chap. CIV.Complex Motion.

Complex motion is that which, to produce some particular action, requires the body to bend downwards and sideways at the same time. The painter must be careful in his compositions to apply these complex motions according to the nature of the subject, and not to weaken or destroy the effect of it by introducing figures with simple motions, without any connexion with the subject.
