In 2007, a pastel drawing came up on the auction market and it was labeled as 19th century German. An astute Canadian collector who bought it had other ideas and sought expert opinion. Most experts now attribute this drawing to Leonardo da Vinci, and it is called La Bella Principessa. The sitter may be the 13-year old daughter of the Duke of Milan, Bianca Sforza. Interestingly, a fingerprint on the paper matches a fingerprint in Leonardo's unfinished painting of St. Jerome. The technique is ink with black, white and red chalk on yellow vellum to give the flesh tones. Leonardo is said to have learned the pastel technique from a French artist.
Even more remarkable is the fact that a lost painting by Leonardo's young rival, Michelangelo appeared in 2009. This Temptation of St. Anthony is now in the Kimbell Art Museum of Fort Worth. Michelangelo painted this oil and tempera when he was only about 13 years old. The first writer of art history in 1570, Giorgio Vasari described a painting that copied an engraving by Martin Schongauer.
The fact that the two greatest artistic prodigies born in Europe during the 1470s, Albrecht Durer and the divine Michelangelo, admired Martin Schongauer, speaks to that master's incredible reputation as an artist in the 15th century. He died young, but his contribution to later art cannot be overlooked. Although Schongauer's travels probably took him only to the center of Europe: Alsace, Burgundy, Flanders and the Rhineland, his prints gave him a reputation throughout Italy, France, Spain and even England. Italians called him Bel Martino. Perhaps he was born around 1448, a few years before another great observer of nature, Leonardo da Vinci. His drawings inspired the great drawings of nature by Durer, namely The Rabbit and Large Piece of Turf.
