Leonardo da Vinci is a prime example of numerous historians and scholars. He was called "Universal Genius" or "Renaissance Man." He has been differently called the father of fossil science, ichnology, and architecture, and broadly viewed as one of the painters ever. Da Vinci was the one who painted the most famous painting in the world, Mona Lisa.

However, according to Business Insider Australia, Leonardo's 530-year-old sketch has quite been revealed in France. The Parisian auction management house Tajan revealed it this week and promptly valued it at 15 million euros ($21 million). It is drawn by a pencil and ink and it is just 7.5 x 5 inches. They believed that the drawing was one of the eight studies that represent "The Martyred Saint Sebastian" that was recorded in da Vinci's Codex Atlanticus notebooks.

Art historians theorize that da Vinci had completed the painting of St. Sebastian, however, it has yet to be found. The draft was discovered by a resigned French doctor among on his late father's papers. Thaddée Prate said that he was fascinated of 16th-century drawing that requires more work. He asked for a second opinion to Patrick de Bayser, an expert of old master drawings. He noticed that the drafts are accompanied by notes that written in Renaissance Italian by somebody who was left handed, which da Vinci was.

The New York Times reported that Prate contacted Carmen C. Bambach, a caretaker of Italian and Spanish drawings at the Metropolitan Museum of Art, for a third opinion about the said draft. According to Dr. Bambach's overview, the newfound drawing is the most very created and appealing of the three known reviews connected with what may have been a lost painting of St. Sebastian. Its not like a monochromatic Hamburg companion, the Paris St. Sebastian is made up in two shades of ink, features few changes to the posture and has a sloping scene out of sight.

Dr. Bambach estimated the sketch's date and it was on 1482 to 1485, during Leonardo's period in Milan, where he painted his first form of "The Virgin of the Rocks." Dr. Bambach said that the drawing represents "Leonardo, full stop," when Sotheby's in London offered a small sheet around 1506 to 1508 that had dark chalk and pen investigations of Hercules and whirlpools.
