Early Italian Baroque came from, and is practically a mixture of the Renaissance and Classical art characteristics. Thus, the formula used to create the early Italian Baroque art style is built upon the techniques, aesthetics and mathematics of the Renaissance and Classical art, from which Baroque art adapted.Baroque artists looked to the Classical, statuesque forms of the Greeks and Romans with their Heroic gestures and bold movements to characterize Baroque figures and portrayed anatomy in correct proportion, with little distortion, just as the Renaissance did.
