to the art image and spatial-temporal forms of its representability. It is the main problem of
this paper - whether any links between forms of art image representability and ontological
foundations of classification of arts exist? For this task the author analyzes the paper «Laocoon:
or, The Limits of Poetry and Painting» by G.E.Lessing. The investigation resulted in the following
thesis. Arts bent for either spatial or temporal forms of representability in works of arts; due to
it arts are divided into three classes: extensive arts, intensive arts and synthetic arts.
