The departure of the Israelites from slavery in Egypt is told in the Old Testament book of Exodus. God guided them at night with the light from a pillar of fire. West painted a dramatic night scene, with the light streaming down on tiny figures of Moses and the Israelites. By 1845, such an epic treatment of a biblical subject was old-fashioned and it is the last of the Bristol School's imaginary, Romantic landscapes.It would be twentieth-century film-makers who were to reinvent the epic dramatisation of history with casts of thousands.
