“Let thine eyes behold the thing which is right,” orders Wisdom, “and keep thine heart with all care.” For the bodily senses easily bring their own impressions into the soul. Therefore we order that henceforth there shall in no way be made pictures, whether they are in paintings or in what way so ever, which attract the eye and corrupt the mind, and incite it to the enkindling of base pleasures. And if any one shall attempt to do this he is to be cut off.
Ancient Epitome of Canon C.
Pictures which induce impurity are not to be painted. Whoso shall transgress shall be cut off.
