At the outset of his career, Thomas Cole, considered the founder of North American landscape painting, produced picturesque views of the Hudson River. Expulsion. Moon and Firelight marks a shift of direction towards an allegorical type of landscape. The central motif is a bridge suspended over a great drop, which the artist saw in the White Mountains in New Hampshire in 1827. Starting with this element, Cole made use of his imagination to create the setting for the Expulsion of Adam and Eve (neither of whom are actually present). The composition is symmetrically structured around the cross shape created by the waterfall and bridge. On the right is Paradise and on the left the world after the Fall. The pronounced contrast between the glowing light inside the arch and the shadow around it emphasises the sublime character of the scene. Cole feared the effects of the rapid industrialisation of the United States and here depicts the North American landscape as a metaphor of Eden.
Moon and Firelight is likewise linked to two works on biblical themes that Thomas Cole exhibited in 1828 at the National Academy of Design in New York and which, as Franklin Kelly has studied, 1 changed the course of his career as a painter: The Garden of Eden and Expulsion from the Garden of Eden. The Fort Worth Garden of Eden depicts the world before the fall and the composition is dominated by an idyllic landscape never before seen. In the Expulsion in the Boston Museum of Fine Arts, Adam and Eve, after being expelled from Paradise, cross a rocky bridge towards a tumultuous natural environment. Cole drew inspiration for the bridge that marks the division between the world of paradise and wild, chaotic nature from a landmark in the White Mountains called “the Bridge of Fear, ” which had attracted his attention during a trip to these parts and featured in numerous drawings in his previous year’s sketchbook.
Both the figures of Adam and Eve and the depiction of Paradise have been removed from the Museo Thyssen-Bornemisza Expulsion, a painting full of paradoxes. The landscape and the elements of creation — the stone bridge, the waterfall, the volcano and the moon — are the only features of the scene. As Kenneth W.Maddox points out in his study of the painting, Cole divides the composition symmetrically by means of the cross formed by the horizontal line of the bridge and the vertical line of the water of the cataract and at the same time establishes a symbolic interplay of contrasts between moonlight and daylight, the fire of the volcano and water, and earth and air, which belong to the aesthetic of the sublime. Both the Boston painting and that in the Museo Thyssen-Bornemisza evidence the influence of the engravings made by the painter John Martin for an edition of John Milton’s Paradise Lost. The mark of the English painter is found not only in the craggy gateway but, in particular, in the use of light to afford the composition dramatic force.
Unlike in the Boston Expulsion, in which Paradise is patently recognisable to the viewer, by eliminating the figures of the expelled in the Museo Thyssen-Bornemisza composition Cole makes the stone bridge, instead of the way to exile, the path to Paradise, which he represents through light and fire, depicting Eden glowing amid the darkness. Cole described the savage American landscape and its ability to transmit God’s work of creation as a metaphor of Eden in his “Essays on American Scenery.” All that separates us from the Garden of Eden is a gateway surrounded by dark rocks leading to a luminous source of hope, which Cole wishes to emphasise, driven by his conviction that “we are still in Eden; the wall that shuts us out of the garden is our own ignorance and folly.”
