Leonardo Da Vinci was left handed, in a time when left handedness was proclaimed by the Vatican to be of the 'devil'. Those born left handed were
commonly forced to use their right hands.
Here is a small bit of information relating to his career. The why's of 'what' he drew or painted, and maybe something to account why some of his work
was left unfinished, (I believe due to the church, or need for actual income)
***************************** below from wicopedia
Growing up in his father's Vinci home, Leonardo had access to scholarly texts owned by family and friends. He was also exposed to Vinci's longstanding
painting tradition, and when he was about 15 his father apprenticed him to the renowned workshop of Andrea del Verrochio in Florence. Even as an
apprentice, Leonardo demonstrated his colossal talent. Indeed, his genius seems to have seeped into a number of pieces produced by the Verrocchio's
workshop from the period 1470 to 1475. For example, one of Leonardo's first big breaks was to paint an angel in Verrochio's "Baptism of Christ," and
Leonardo was so much better than his master's that Verrochio allegedly resolved never to paint again. Leonardo stayed in the Verrocchio workshop until
1477 when he set up a shingle for himself.
In search of new challenges and the big bucks, he entered the service of the Duke of Milan in 1482, abandoning his first commission in Florence, "The
Adoration of the Magi". He spent 17 years in Milan, leaving only after Duke Ludovico Sforza's fall from power in 1499. It was during these years that
Leonardo hit his stride, reaching new heights of scientific and artistic achievement.
The Duke kept Leonardo busy painting and sculpting and designing elaborate court festivals, but he also put Leonardo to work designing weapons,
buildings and machinery. From 1485 to 1490, Leonardo produced a studies on loads of subjects, including nature, flying machines, geometry, mechanics,
municipal construction, canals and architecture (designing everything from churches to fortresses). His studies from this period contain designs for
advanced weapons, including a tank and other war vehicles, various combat devices, and submarines. Also during this period, Leonardo produced his
first anatomical studies.
Alas, Leonardo's interests were so broad, and he was so often compelled by new subjects, that he usually failed to finish what he started. This lack
of "stick-to-it-ness" resulted in his completing only about six works in these 17 years, including "The Last Supper" and "The Virgin on the Rocks,"
and he left dozens of paintings and projects unfinished or unrealized.......
so you see, I think Leonardo was not necessarily gifted with outright Genius but rather somewhat forced into the interests of the time such as
weapons, and on his own, might or likely would have been uninterested.
I think he was also lured by promises of 'wealth' or big pay, that prevailed on his direction in art. Very skilled....yes, Clever.....yes, cultivating
the monetary possibilities.... yes, using that cleverness and a certain knowledge of methodologies that were known by only an exclusive few......
likely. Human like all the rest of us..... yes. Necessity is the mother of invention, and I think it true in Leonardo's time. Deeper mysteries in his
paintings....... perhaps, though I feel not to such a degree as some would wish to convey. To focus so narrowly on one of his abilities and dismiss or
minimalize the rest would not give the real picture of who and what Leonardo was.
