Hannibal and Army Crossing Alps. Snow Storm: Hannibal and his Army Crossing the Alps is an oil on canvas painting by J. M. W. Turner, first exhibited in 1812.
Left to the nation in the Turner Bequest, it was acquired by the National Gallery in London in 1856, and is now held by the Tate Gallery. The painting depicts the struggle of Hannibal's soldiers to cross the Maritime Alps in 218BC, opposed by the forces of nature and local tribes.
A curving black storm cloud dominates the sky, poised to descend on the soldiers in the valley below, with an orange-yellow Sun attempting to break through the clouds. A white avalanche cascades down the mountain to the right.
Hannibal himself is not clearly depicted, but may be riding the elephant just visible in the distance. The large animal is dwarfed by the storm and the landscape, with the sunlit plains of Italy opening up beyond.
In the foreground, Salassian tribesmen are fighting Hannibal's rearguard, confrontations that are described in the histories of Polybius and Livy. The painting measures 146 × 237.5 centimetres. It contains the first appearance in Turner's work of a swirling oval vortex of wind, rain and cloud, a dynamic composition of contrasting light and dark that will recur in later works, such as his 1842 painting Snow Storm: Steam-Boat off a Harbour's Mouth. Turner saw parallels between Hannibal and Napoleon, and between the historic Punic War between Rome
