Composition.



The term Composition, in its general sense, signifies the union of
things that were originally separate: in the art of Painting it
implies, in addition to this, such an arrangement and reciprocal
relation of these materials, as shall constitute them so many
essential parts of a whole.

In a true Composition of Art will be found the following
characteristics:--First, Unity of Purpose, as expressing the general
sentiment or intention of the Artist. Secondly, Variety of Parts, as
expressed in the diversity of shape, quantity, and line. Thirdly,
Continuity, as expressed by the connection of parts with each other,
and their relation to the whole. Fourthly, Harmony of Parts.

As these characteristics, like every thing which the mind can
recognize as true, all have their origin in its natural desires, they
may also be termed Principles; and as such we shall consider them. In
order, however, to satisfy ourselves that they are truly such, and not
arbitrary assumptions, or the traditional dogmas of Practice, it may
be well to inquire whence is their authority; for, though the ultimate
cause of pleasure and pain may ever remain to us a mystery, yet it is
not so with their intermediate causes, or the steps that lead to them.
