"Leonardo’s fame as an artist is based on only a few works, for many other interests took him away from painting. Unlike his humanist contemporaries, he was not particularly interested in Classical literature or archaeology. Instead, his passions were mathematics, engineering, and the natural world. He compiled volumes of detailed drawings and notes on anatomy, botany, geology, meteorology, architectural design, and mechanics. In his drawings of human figures, he sought not only the precise details of anatomy but also the geometric basis of perfect proportions. Leonardo’s searching mind is evident in his drawings not only of natural objects and human beings, but also of machines, so clearly and completely worked out that modern engineers have used them to construct working models. He designed flying machines, a kind of automobile, a parachute, and all sorts of military equipment, including a mobile fortress. His imagination outran his means to bring his creations into being. For one thing, he lacked a source of power other than men and horses. For another, he may have lacked focus and follow-through. His contemporaries complained that he never finished anything and that his inventions distracted him from his painting."
"The seventeenthcentury French critic Roger de Piles (1635–1709) described this exchange when he wrote: “True painting … calls to us; and has so powerful an effect, that we cannot help coming near it, as if it had something to tell us."
"Throughout her life, Gentileschi painted many such images of heroic biblical women, which art historians have interpreted in relation to her own struggle to claim her rightful place in an art world dominated by men."
