Leonardo Da Vinci,  son of Caterina, a peasant girl and Ser Piero da Vinci, a Florentine notary, is one of the most amazing men who have ever lived. He is considered to be the greatest geniuses of the Italian renaissance. Not only was he a great painter, whose pictures the “Mona Lisa” and “The Last Supper” are among the most famous in the world, but also a sculptor, an architect, a poet and a composer music.

He was a genius of another kind too, for he was a pioneer in science, he studied mathematics and engineering and his ideas and the discoveries he made in work were hundreds of years in advance of his time.

His studies of human anatomy was based on meticulous dissection and showed great knowledge which was far superior to his contemporaries in medical profession.

According to Dr Kenneth D Keele’s strong words -” thus in anatomy as in so many aspects of life’s work, Leonardo was a man who awoke too early in the dawn of the Scientific Renaissance whilst others still slept”

He is an inspiration to many doctors and several interesting medical articles have been written analysing his exquisite  illustrations of human anatomy.

To his remarkable knowledge was added his skill unique skill in recording his findings in paper. These are not only important scientific diagrams but also superb works of art.

The studies of the skeleton and muscles completed between 1508 and 1510 are among his most impressive and beautiful drawings. These beautiful illustrations emphasize the fact that a good diagram will tell more than a thousand words.

The Spine (1508 -10) shows the beautiful natural curve of the vertebral  column, with the vertebrae of each part correctly numbered for the first time.

His drawing “Superficial muscles and veins of  arms shows also the superficial veins of the chest and abdomen.

He was the first to observe and comment on the fetal membranes—the chorion,  amnion, and allantois.  His drawing of a fetus in the womb is altogether remarkable and was not bettered for more than two centuries. Of that drawing, he wrote:

“In the case of this child the heart does not beat and it does not breathe because it lies continually in water. And if it were to breathe it would be drowned, and breathing is not necessary to it because it receives life and is nourished from the life and food of the mother.

The navel is the gate from which our body is formed by means of the umbilical vein… This umbilical vein is the origin of all the veins of the creature that is produced in the matrix, and it does not take its origin in any vein of the pregnant woman, because each of these veins is entirely separated and divided from the veins of the pregnant woman, and the veins and arteries are found together in pairs; and it is extremely rare for one to be found without the other being in company with it, and the artery is almost always found above the vein because the blood of the artery is the passage for the vital spirit, and the blood of the veins is that which nourishes the creature…. (the unborn child) is nourished from the same cause as the other members of the mother, and its vital powers are derived from the air which is the common living principle of the human race and other living things.”

In the course of dissection of the skull and brain Leonardo made many discoveries like maxillary and frontal sinuses (1489).

He was interested in ophthalmology and was probably first to draw the optic chiasma and to demonstrate the path of vision from the back of the eyeball to the base of the brain as in the “Optic Chiasma and cranial nerves”  (1506 -1508).

Leonardo Da Vinci described eye as the “window of the soul.”

He believed strongly in health care. His instructions have a remarkably modern ring:

If you would keep healthy, follow this regimen: do not eat unless you feel inclined, and sup lightly; chew well, and let what you take be well cooked and simple. He who takes medicine does himself harm; do not give way to anger and avoid close air; hold yourself upright when you rise from table and do not let yourself sleep at midday. Be temperate with wine, take a little frequently, but not at other than the proper meal-times, not on an empty stomach; neither protract nor delay the (visit to) the privy. When you take exercise let it be moderate. Do not remain with the belly recumbent and the head lowered, and see that you are well covered at night. Rest your head and keep your mind cheerful; shun wantonness, and pay attention to diet.

“As a well spent day brings happy sleep, so life well used brings happy death.” Leonardo da Vinci
