Again, Leonardo has simplified the design, by having the left shoulder band covered by the sbernia, so as to not take away from the animal's detailed head. Her coiffure, known as a coazone, confines her hair smoothly to her head with two bands of it bound on either side of her face and a long plait at the back. Her hair is held in place by a fine gauze veil with a woven border of gold-wound threads, a black band, and a sheath over the plait. As in many of Leonardo's paintings, the composition comprises a pyramidic spiral and the sitter is caught in the motion of turning to her left, reflecting Leonardo's lifelong preoccupation with the dynamics of movement. The three-quarter profile portrait was one of his many innovations. Il Moro's court poet, Bernardo Bellincioni, was the first to propose that Cecilia was poised as if listening to an unseen speaker. This work in particular shows Leonardo's expertise in painting the human form. The artist painted Cecilia's outstretched hand with a lot of detail, including the shape of each fingernail, the lines around her knuckles, and even the way the tendon in her bent finger moved as it bent The ermine The animal resting in Cecilia's arms is usually known as an ermine. Commentators have noted that it is too large to be an actual ermine, but its size is explained by its being of a largely symbolic nature. The art historian Luke Syson notes that "Naturalism is not the point here; Leonardo has created a mythical beast, the composite of several animals he drew at this time". There are several interpretations of the ermine's significance and they are often used in combination with each other. In its winter coat, the ermine was a traditional symbol of purity and moderation, as it was believed it would face death rather than soil its white coat. In his old age, Leonardo compiled a bestiary in which he recorded: "The ermine out of moderation never eats but once a day, and it would rather let itself be captured by hunters than take refuge in a dirty lair, in order not to stain its purity." He repeats this idea in another note, "Moderation curbs all the vices. The ermine prefers to die rather than soil
