LA BELLA PRINCIPESSA by Leonardo da Vinci?

La Bella Principessa ( "The Beautiful Princess"), also known as Young Girl in Profile in Renaissance Dress and Portrait of a Young Fiancée, is a portrait in coloured chalks and ink, on vellum, of a young lady in fashionable costume and hairstyle of a Milanese of the 1490s.

"What a wondrous thing: a newly attributed portrait by the man who painted the Mona Lisa - Leonardo da Vinci  – but the principessa might not be quite so bella after all. She may, in fact, be Sally from the Co-op. Convicted art forger Shaun Greenhalgh claims that he faked this “Leonardo” and that the model is a girl he knew in Bolton in 1975."

La Bella Principessa: The Story of the New Masterpiece by Leonardo Da Vinci
Book by Martin Kemp and Pascal Cotte (2010)

'' In October 2009, a major artwork by Leonardo da Vinci was uncovered. The 500 year-old portrait is one of the most extraordinary discoveries of our time. This is the story of how a team of experts - led by Professor Martin Kemp -pieced together the evidence, detailed historical research and technical analysis to follow a trail that leads back to the 15th Century. There is an element of mystery and an aura of mystical glamour that surrounds Leonardo. Martin Kemp takes us on a journey of discovery recounting the steps he and Pascal Cotte took in authenticating the painting including the use of forensic methods usually reserved for criminal investigation. He recounts how experts matched a fingerprint found on La Bella Principessa to the great Renaissance master. This discovery throws new light on Leonardo da Vinci and his world. 

The sitter, a beautiful young girl, displays a sense of melancholy and strength, a tender and fragile beauty. But who is she? By far the most likely candidate is the illegitimate daughter of Duke Ludovico Sforza. Martin Kemp tells, too, the tragic story of this princess who was to die when she was just fourteen years old. 

 As 'La Bella Principessa' (The Beautiful Princess) finally goes on display to the world, the people responsible for proving it is one of Leonardo da Vinci's tell the story of its discovery. La Bella Principessa reveals the Renaissance and its great master in a new light."

My interpretation of this controversial 'La Bella' colour portrait uses an amalgamation of Renaissance oil paintings and photographic collage to create an individual and contemporary woman.  Sections of background from 'The Ghent Altarpiece' by Jan Van Ecyk forms part of the overlaid design on the body, combined with my drawn nude repeat patterns.
