There are two versions of Leonardo da Vinci's Madonna of the Rocks (the Louvre version was painted first). These two paintings are a good starting point for defining the qualities of the new High Renaissance style. Leonardo painted both pictures in Milan, where he had left Florence.
Mary's left hand hovers protectively over her son's head, while an Angel looks outwards and points to St John.
Here, it is this Angel that is shown in detail.
High Renaissance artists could do more with the body - make it more complex, more elegant and more graceful. Similarly, the compositions of High Renaissance paintings are more complex and sophisticated than those of the Early Renaissance: the figures interact through gestures and glances, and are often intertwined and placed in the shape of a pyramid.
