one is given to understand, was inspired by one of the master's lovers; it is a marble representation of someone Michelangelo loved.The creation of David is instructive in many respects. First, and rather obviously, it represents something the master held dear, dear enough to expend much time and energy to complete for it took many years to sculpt. Second, Michelangelo did not sculpt it alone; he was assisted by a series of other master sculptors and a number of apprentices. David, therefore, is the result of concerted effort over a protracted period. Third, David is not as large as one would imagine, nor is it perfect; David's hands are extremely large in proportion to the torso. It does not quite meet the expectations of all the tourists who flock to Florence to see it; indeed, some (heretics!) wonder what all the fuss is about. It would be a mistake, however, to expect that David could ever be perfect. It was sculpted by differentially skilled masters and apprentices; mistakes would inevitably have been made by some apprentices, even some masters, but then rectified under the careful eye of a master or senior master. Sculptors learned their art while they were creating David, sometimes with dogged tenacity. Fourth, its minor "imperfections" are what make David unique or, at the very least, contribute to its idiosyncrasy.Clinical development units (CDUs) are, or could be, nursing's David: nursing's masterpiece.
