This pastel is believed to be Bianca Sforza, age 13. A fingerprint matches that of Leonardo, and the left-handed hatching is also a signature of his style

Since 1993, Martin Schongauer’s 10″ x 13″ drawing of Peonies has been in the Getty Museum, Los Angeles..

 

A painting of peonies came up for auction in 1990 under the vague label of Northern Italian. However, a museum curator at the Albertina in Vienna recognized it as an important drawing from about 1472-73 by Martin Schongauer, an artist who lived in Alsace on the French-German border. The drawing, now in the Getty Museum, is a study for the flowers in Madonna of the Rosary, 1473, painted by Schongauer for a church in Colmar (now in France). Albrecht Durer traveled to Colmar to visit Schongauer in 1491, but the great Alsatian master had died by the time 21-year old Durer arrived. Martin’s brothers met with him and gave him some of the master’s drawings. This drawing may have been one of the drawings owned by Durer; the same Viennese curator recognized a flower similar to one of the peonies in a Durer painting of 1501.

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.

 
A badly damaged painting supposedly by a student of Leonardo sold for 45 British pounds in 1958. Only in the past year has it been cleaned and recognized as an authentic Leonardo da Vinci. Called the Salvator Mundi, it was recently part of an exhibition at the National Gallery in London. In the frontal image, Jesus holds a glass globe and stares directly at the viewer while using the blessed gesture. His calm face is full of compassion and kindness. The penetrating sense of life in this image is clearly palpable, as revealed after its cleaning. It has Leonardo’s recognizable sfumato, the smoky quality which gives a dark softness to the shadows. It has the iconic and mysterious qualities reminiscent of as the Mona Lisa. Cleaning revealed this Salvator Mundi to be an authentic
Leonardo da Vinci dating to c. 1500

Martin Kemp, Leonardo expert in England, has identified the rock crystal orb to show the crystalline cosmos in Jesus’s hand as something only Leonardo could have painted with accuracy. Leonardo was quite the geologist and Kemp compared the painted example to crystal orbs in the geology collection of the Ashmolean Museum. Therefore, the painting could not have been done by a follower. The last time a painting was discovered to be by Leonardo was 100 years ago.

Only the master Leonardo, who intimately studied nature,
could have portrayed this rock crystal so accurately


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.
