An allegorical portrait by Benjamin West depicting Benjamin Franklin's 1752 kite experiment. Franklin is shown with scientific instruments and assisting putti amidst a lightning storm.

Benjamin West painted this allegorical portrait of Benjamin Franklin around 1816. It depicts the scientist during his 1752 experiment to prove that lightning is an electrical phenomenon. Franklin sits on a cloud-like formation, reaching up to a key suspended from a kite string. A bolt of lightning strikes the kite in the background, which illuminates the dark sky. The composition uses several figures to assist Franklin. Three putti help manage the kite string and scientific apparatus. One child holds the string while others interact with Leyden jars, which were used to store electrical charge in the eighteenth century. This inclusion of mythological figures alongside scientific equipment is typical of West's later style. It elevates the subject from a simple historical record to a heroic event. Franklin is dressed in a dark suit with a white cravat, draped in a large red cloak that billows behind him. His expression is calm and focused, contrasting with the turbulent weather and the energetic movements of the children. The palette is dominated by dark greens and greys alongside the deep red of the fabric. Bright flashes of white and yellow represent the electrical discharge and the light breaking through the storm clouds. West was a close friend of Franklin and painted this work late in his career while living in London. The painting was intended as a study for a larger commission that was never completed. It remains a significant depiction of the experiment, combining Enlightenment science with the dramatic visual language of Romanticism. The work reflects the contemporary fascination with electricity as a force of nature that could be understood and harnessed through human reason.
