The paintings of William Blake were based on: his vivid imagination

Explanation:

    English poet, painter, typographer and engraver William Blake soon revealed the visionary and mystical tendency. His first vision came at age nine when he claimed to have seen angels adorning sequined tree branches. Some time later, as he contemplated workers arranging bales of hay, he saw angelic entities walking among them.

    His poetics were the natural manifestation of an extremely talented and inventive being. He usually resorted to the white verses, characteristic of Elizabethan times. Blake would always be a nonconformist by nature, a challenger of the fast-paced journey of Science and Reason, so he was not understood and well accepted by the people of his day who saw him as an eccentric. Consequently the author never made a fortune with his work, of a mystical and prophetic nature, always depending on his companions to alleviate his penury.
