Looking into the works of Ray Harryhausen, I discovered one of his earlier influences to be the English romantic painter John Martin. His works are amazing with a great fantasy quality capturing environments that are grand, epic and visually striking. The use of humans in several of the pieces help further indicate the sense of scale and space within the piece, where the composition of swirling clouds or rock frame the piece creating a dynamic and epic atmosphere out of this world.
The last two pieces were found in Ray Harryhausen's book.
I am most fond of Martin's works, bearing a fantastic fantasy and conceptual quality that were conceived in the 19th century! They are simply wonderful in their concepts and composition of grand environments that is greatly inspiring.
