I prefer you to take as your model a mediocre sculpture rather than an excellent painting, for from painted objects we train our hand only to make a likeness, whereas from sculptures we learn to represent both likeness and correct incidence of light.

-Alberti, Leon Battista
  On Painting (translated by Cecil Grayson).

And God spake all these words, saying,Iamthe L thy God, which have brought thee out of the land of Egypt, out of the house of bondage. Thou shalt have no other gods before me. Thou shalt not make unto thee any graven image, or any likeness of any thing that isinheaven above, or that isin the earth beneath, or that is in the water under the earth: Thou shalt not bow down thyself to them, nor serve them: for I the L thy God am a jealous God, visiting the iniquity of the fathers upon the children unto the third and fourth generation of them that hate me; And shewing mercy unto thousands of them that love me, and keep my commandments. Thoushalt nottakethename of the L thy God invain; for the L will not hold him guiltless that taketh his name in vain. Remember thesabbath day, to keep it holy. Six daysthou shalt labour and do all thy work: But the seventh day is the sabbath of the L thy God: in it thou shalt not do any work, thou, nor thy son, nor thy daughter, thy manservant, nor thy maidservant, nor thy cattle, nor thy stranger that is within thy gates: For in six days the L made heaven and earth, the sea, and all that in them is, and rested the seventh day: wherefore the L blessed the sabbath day, and hallowed it. Honour thy father and thy mother: that thy days may be long uponthelandwhichtheL thy Godgiveththee. Thou shalt not kill. Thou shalt not commit adultery. Thou shalt not steal. Thou shalt not bear false witness against thy neighbour. Thou shalt not covet thy neighbour's house, thou shalt not covet thy neighbour's wife, nor his manservant, nor his maidservant, nor his ox, nor his ass, nor any thing that is thy neighbour's.
