Art is likely to be poetic if it leaves out detail or conceals information or suggests the interpretation of the detail. It may suggest the influences and moods that are poetic.
The composition of poetry implied draws strong parallels the message of the painting. It starts with an idea, a subject, a theme, or often a distinct feeling.
It is the artist that takes pen or brush to canvas or paper and brings the poetic message to life.
“Painting is poetry that is seen rather than felt, and poetry is painting that is felt rather than seen.”
― Leonardo da Vinci
