If you are fond of copying other Men's Work, as being Originals more
constant to be seen and imitated than any living Object, I should rather
advise to copy anything moderately carved than excellently painted: For
by imitating a Picture, we only habituate our Hand to take a mere
Resemblance; whereas by drawing from a carved Original, we learn not
only to take this Resemblance, but also the true Lights.
_Leon Battista Alberti._
