David Martin (artist) in the context of "Polymaths"

A polymath or polyhistor is an individual whose knowledge spans many different subjects, known to draw on complex bodies of knowledge to solve specific problems. Polymaths often prefer a specific context in which to explain their knowledge, but some are gifted at explaining abstractly and creatively.

Embodying a basic tenet of Renaissance humanism that humans are limitless in their capacity for development, the concept led to the notion that people should embrace all knowledge and develop their capacities as fully as possible. This is expressed in the term Renaissance man, often applied to the gifted people of that age who sought to develop their abilities in all areas of accomplishment: intellectual, artistic, social, physical, and spiritual.

Portrait of Benjamin Franklin is a 1767 portrait painting by the Scottish artist David Martin of the American politician and inventor Benjamin Franklin. It was painted during his lengthy residence in London when he was acting as colonial agent for Pennsylvania, Georgia, New Jersey, and Massachusetts. The work was commissioned by the Edinburgh merchant Robert Alexander, a friend of Franklin. He is shown seated next to a bust of the scientist Isaac Newton.

The painting was displayed at the Exhibition of 1767 held by the Society of Artists held at Spring Gardens. Today it is part of the collection of the White House.
