La Bella Principessa (English: "The Beautiful Princess"), also known as Portrait of Bianca Sforza, 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.
 Sold at auction in 1998 as an early 19th-century German work, some experts have since attributed it to Leonardo da Vinci.
 In 2010 one of those experts, Martin Kemp, made it the subject of his book "La Bella Principessa: The Story of the New Masterpiece by Leonardo da Vinci".
 Evidence discovered in 2011 accounting for its provenance has strengthened the case for it being by Leonardo; the sheet appears to have been cut from a Milanese book of which the remainder has long been in Warsaw, which comes from the "milieu" of Ludovico Sforza, Leonardo's employer.

 The version collected by the Brothers Grimm was an orally transmitted version of the originally literary tale published by Charles Perrault in "Histoires ou contes du temps passé" in 1697.
 This in turn was based on "Sun, Moon, and Talia" by Italian poet Giambattista Basile (published posthumously in 1634), which was in turn based on one or more folk tales.
 The earliest known version of the story is found in the narrative "Perceforest", composed between 1330 and 1344 and first printed in 1528.
A spectrograph is an instrument that separates light into a frequency spectrum and records the signal using a camera.
